Mobile Tv going in Hibernation!

Earlier this month, there was this report which mentioned that 'Mobile 3.0' (a consortium in Germany) decided to end plans to launch a DVB-H (handheld) network. The failure was blamed to some extent on the wireless service providers who were not abole to get their act together to establish a paid DVB-H infrastructure.

The following is an extract from the article:

Burda and Holtzbrink, both publishing houses, and South African media company Naspers have thrown in the towel and won't launch a DVB-H network in Europe, the reports said.

Their effort wasn't helped when service providers said they plan to introduce mobile TV devices that use the free DVB-T technology. Noting that subscribers aren't likely to favor the idea of paying for TV on top of their often hefty wireless charges, service provider Vodafone has said it favors a mobile TV strategy whereby consumers pay for add-on video services that are offered in conjunction with free mobile TV. Mobile 3.0 had planned to charge monthly fees of as much as $10 to $15.

The Mobile 3.0 group had begun testing a service with nine TV channels and three radio stations.

The German situation isn't likely to influence the delivery of mobile TV in the United States, which is still in its embryonic stage. To date, no major third-party providers of mobile TV have emrged in the United States.

According to a report in Mobile burn the same day as the above news:

Toshiba announced that it was shutting down Mobile Broadcasting Corp. at the end of March 2009, stating that the company has not gained enough subscribers due in large part to the popularity of the free TV broadcasting that many of Japan's phones are now capable of receiving (and even recording).

The situation is different on many levels in the U.S. The nation's two largest carriers, AT&T and Verizon Wireless, both use Qualcomm's MediaFLO (definition) mobile TV standard on their TV compatible cell phones. While different technically, MediaFLO and DVB-H work on the same basic premiss of broadcasting a separate, mobile optimized digital TV signal over the air that compatible devices can receive. Since AT&T and Verizon more or less control the handset models that are available to its customers, much as is the case with German carriers, the two have been able to steer subscribers into using the MediaFLO system while avoiding competition from devices that could otherwise pick up free broadcast TV signals. Similarly, Sprint offers a streaming TV service on most of its handsets. T-Mobile currently offers no integrated TV support to its customers.

Then we had the bad news about Mobile Tv in Korea:

Some new numbers on mobile TV's non-pickup in Korea...more specifically, the TV broadcasting using digital multimedia broadcasting (DMB) format. The story says DMB, which includes the free terrestrial and premium satellite DMB-- has an audience of some 13.7 million, according to latest data. That's up from nine million in December last year. The number of DMB-enabled receivers sold here reached 13.69 million in June.

-- Mobile phones accounted for 48.4 percent of all DMB subscribers.-- Car navigation systems and other DMB-enabled terminals used in vehicles accounted for 37.8 percent of DMB receivers, followed by portable media players at 9.4 percent and USB devices at 3.8 percent.?Laptop computers were the least popular DMB device, accounting for just 0.9 percent of all receivers.

Bu the overall viewership numbers remain minuscule: TNS Media, a local research firm, overall viewer rating for the day was just 1.172 percent, peaking at 3.585 percent during the commuting hours of 6 to 7 p.m. in the survey. And, even more surprising: male viewers in their 50s proved the largest audience for mobile TV rather than the convention wisdow that tech-savvy youngsters would be watching TV on the go. Viewership was also relatively high among men in their 40s and 30s, but minuscule among women and younger customers.

We have completely stopped hearing anything new on MBMS. There is no news on Mobile TV trials. I think that Mobile Tv is going in Hibernation and will be for some time, until some killer charging models are in place for these kinds of services.

Free TD-SCDMA phones with Mobile TV


China Mobile, the nation's largest mobile carrier, is to purchase around 40,000 TD-SCDMA mobile television phones tailored for China Mobile Multimedia Broadcasting (CMMB), Chinese telecoms equipment provider ZTE Corporation disclosed on July 8.

A handful of telecoms terminal providers including ZTE and Qualcomm Incorporated are preparing for the purchase. These mobile phones are scheduled to be offered to friendly users during the 2008 Beijing Olympic Games in August. Their wider usage is expected to come after the Olympics.
The Chinese telecoms authority has approved the market access of CMMB mobile television phones in the country. In fact, China Mobile is busying itself in furthering the mobile television phone technology - TD-Multimedia Broadcast Multicast Service (MBMS), and it plans to widely promote TD-MBMS mobile television phones after CMMB ones.

The State Administration of Radio Film and Television of China (SARFT) is designed to start commercial CMMB service in 37 capital cities across the country before the Olympics. So far, close to 30 cities have finished building the networks.

Mobile TV! Still no joy

Mobile TV is floundering in one of its bastion (Korea ... other one being Japan). The following is from a report in telecoms.com:

With mobile TV services in the flagship market of South Korea floundering and with few signs that operators anywhere else have found a successful formula for launching such services, most operator and vendor delegates at the recent CommunicAsia Summit in Singapore struggled to find enthusiasm for the fledgling industry.

Some operators and vendors say that mobile TV should be subscription-based, to offer a reliable revenue stream; others say an ad-supported model is the most viable option; and still others argue that a combined pay/advertising approach is the way forward.

Figures from South Korea seem to suggest that both pay-based and ad-supported models have critical weaknesses, which would also apply in other markets in the region. A lot more experimentation and creativity from operators might be required to find the right model.
Those promoting the idea of a pay-based service say that only by charging for content can a business model work. They say operators must team up with content firms to acquire premium content - most particularly sports - that people will be willing to pay a monthly fee to view or even pay for on a per-view basis.


But this line of thinking seems flawed, given that there is a limited amount of blue-chip content for which people will be prepared to pay, most notably live sports events - such as English Premier League soccer games - or highlights of them.

The problem is, of course, that content-rights holders have become adept at exacting a premium price for key sports rights, meaning that mobile TV operators would have to recoup their heavy capital investment by charging high subscription fees.

This is a problem, since the high churn rate experienced by TU Media in South Korea seems to suggest that mobile TV subscribers are extremely price-sensitive.

TU Media subscribers pay just KRW13,000 ($12.60) a month for the service but have been leaving in droves after their initial one-year contracts finish, forcing the firm to offer significantly reduced subscription rates to keep subscribers from deserting the service.

TU Media's experience suggests that mobile TV subscribers will be willing to pay only so much for services and that although blue-chip sports content has a crucial role to play, operators must find a way to acquire the content without paying excessive prices.

On the advertising side of the debate, many delegates at CommunicAsia argued that an ad-based strategy would work best for mobile TV platforms but that operators would have to be extremely creative in their approach.

There is no magic bullet that will provide a successful business model, but there seems to be a reasonable possibility that an attractive model can be built if operators can match the largely young and technology-friendly subscribers viewing mobile TV on their handsets with advertisers desperate to reach such a market.

Intriguingly, conference delegates also discussed the possibility that broadcast-type mobile TV services might never fully take off in the region and that Multimedia Broadcast Multicast Service (MBMS) video streaming over high-speed HSPA and future LTE networks would dominate the market.

The debate has strong proponents on both sides. Many vendors back an MBMS approach, saying that experience shows that broadcast-style services are not what users are demanding and that the more-narrowly targeted VOD-style content being offered on HSPA networks is already proving hugely popular.

The pro-MBMS argument also runs that with HSPA/LTE networks already in place and offering voice, data and video services, why go to the expense of deploying a terrestrial or satellite-based mobile TV network, especially with the expense involved in creating high-quality in-building reception?

Although this is a persuasive argument, it has shortfalls, most notably the fact that even LTE networks will still be point-to-point networks and will be unequipped to operate as point-to-multipoint services, which a full broadcast mobile TV service would require.
The broadcast-mobile-TV lobby argues strongly that the core strengths of broadcast-based networks cannot be replicated by even high-speed mobile networks, which would not be able to support the huge demand that's sure to arise for broadcasts of live sports and important news events.


In reality, the MBMS-vs.-broadcast-mobile-TV debate is spurious, given that both technologies are going to be on the market, and it will be users who determine which is the more successful.
At this early stage, it looks likely that subscribers and operators will use high-speed, quality video streaming for VOD-based "snacking" on content and that full broadcast mobile TV will be used for some live events, for which only a broadcast-style service can supply the quality of service required.


Korean Insight has an interesting section on Mobile TV (but no blogs on this topic for some time). A blog on this topic last year says a lot:

As TU Media started operations in mid 2005 it tried to acquire simultaneous re-transmission rights from broadcasters. This means that S-DMB viewers would be able to watch popular dramas and shows simultaneously with fixed TV. These contents are considered the most popular on both fixed and mobile TV. However, previously have broadcasters been reluctant to share these contents because they wanted to use it for their own T-DMB service. This is why S-DMB had to focus on other contents like sports and news. But the lack of “killer” contents from fixed TV hindered S-DMB development (as shown in the graphic above). Until today it had been able to acquire approximately 1.26 million subscribers. But according to TU Media they need approximately 2.5 million subscribers to be profitable.

But also T-DMB is struggling to build a profitable business. Despite more than seven million T-DMB devices in Korea the advertising revenues are marginal. Which partially is the result of very restrictive legislation on advertising but also broadcasters have failed to develop an attractive mobile advertising value proposition to make this channel more attractive for advertisers.

Consumers have embraced this new medium and it is very likely that broadcasters will take mobile TV more serious and endeavor to make mobile TV advertising more attractive for broadcasters. Until 2012 more than 20 million T-DMB devices are expected, so mobile TV has a future in Korea.

Qualcomm to back MediaFLO at the expense of MBMS

Just couple of days back I was complaining about everyone abandoning MBMS but now I can see why Qualcomm is suddenly uninterested in MBMS:

U.S. mobile technology company Qualcomm Inc. (QCOM) said Friday that it acquired an L-band radio spectrum licence for GBP8.3 million that will enable it to bring new mobile TV and wireless services to the U.K.

Qualcomm U.K. Spectrum Ltd bought the licence to use 40 Megahertz of the 1452 MHz to 1492 MHz band in an auction by communications regulator Ofcom.

The licence is suitable for offering mobile television, wireless broadband and satellite radio, Ofcom said.

The L-Band spectrum license acquired by Qualcomm covers the entire United Kingdom and is technology neutral, thereby enabling Qualcomm to use the spectrum for innovative technologies, depending on its assessment of market needs in the United Kingdom.

The L-band, on which any technology or service can be used, will contend with two main rivals, DVB-H, backed by Nokia, the handset maker, and by Viviane Reding, the European Telecoms Commissioner, who wants to make it the European standard, and TDTV, which is being tested by Orange and T-Mobile in the UK. All three technologies would require special handsets able to pick up a broadcast signal.

Mobile companies including Vodafone and 3 already offer mobile television in Britain, but take-up has been poor.

Qualcomm said that it does not intend to run a mobile TV broadcasting network as an operator, as it has done in the United States, but is looking for partners to launch its mobile television technology, MediaFLO.

Andrew Gilbert, head of Qualcomm's European operations, said: “We will not attempt to become an operator, but if service providers want to partner with us ... we are open to talking to folk.” Mr Gilbert added that Qualcomm would use the spectrum to bring a variety of wireless technologies to the UK market but that it had no timetable for launches in mind.

With industry heavyweights supporting DVB-H and TDTV, analysts see this as Qualcomm's last chance to bring MediaFLO to the UK and European markets. Will Harris, of Enders Analysis, said: “One potential outcome from this is that two competing mobile TV services could be launched. While it is too early to say which technology will win at this stage, those that fail to get support from the mobile operators will lose.”

O2, the mobile network provider, was initially interested in the L-band auction, but pulled out without bidding. Failed bidders include WorldSpace, the satellite radio group, and The Joint Radio Company, which runs spectrum for the UK energy industry.

The next competition, to run later this year, is even more significant. It has a price tag that could run into the tens of millions because it is for a frequency that supports WiMax, a high-speed network technology similar to a common WiFi home wireless system, but with a more robust signal and a range of a kilometre or more.

Although WiMax is not new it has had little success so far. But interest is hotting up. In the US last week, Sprint Nextel announced a $14.5bn (£7.4bn) joint venture with Clearwire to build a network servicing as many as 140 million people by the end of 2010. And Google is pumping another $500m into the scheme.

At the moment, the UK market is small. Freedom4 and UK Broadband, a subsidiary of PCCW, are the only providers with a national licence, and only limited services are available. But developments on the other side of the Atlantic are fuelling interest, and some big players are lining up for the relevant spectrum auction. Ian Livingston, who takes over aschief executive at BT in two weeks' time, has said thecompany is interested, and Vodafone has trials running in Malta.

Freedom4 is also already in talks with potential investors about the £100m infrastructure funding it estimates it will need from 2009-11. "We are talkingto our partners and the banks," Mike Read, chief executive of Freedom4, said. "Following the deals in the US, there is moreinterest in what we are doing over here."

Ian Keene, a senior analyst at Gartner, said: "There is abusiness case for WiMax in the UK, but most likely it will becity-centric and focused on business, rather than nationalcoverage competing with mobile networks."

The biggest auction of all will be next year's bidding for the "digital dividend" – the wide bands of frequency freed up when the analogue television signal is switched off in 2012. The debate about who should get what is already well under way. Broadcasters claim a substantial portion for high-definition TV, mobile operators want it for next-generation cellular services such as video, and internet service providers say it iscrucial for the broadbandinfrastructure.

MBMS - R.I.P.

Even though slow progress on MBMS (Multimedia Broadcast Multicast Service) has been going on for some time, just found out through sources that the two biggest promoters of this technology have put it on backburner. The reason they cite is the lack of interest from operators. They do not have a burning need for Mobile TV technologies as they are still able to cope with the demand by streaming point to point connections.

Somebody told me on condition of anonymity that the big operators in UK are at a breaking point but the things are still surviving because in the peak hours (9am to 5pm) there is not much demand for Mobile TV and the voice occupies the complete bandwidth. Whereas after 7pm and before 7am there is an even distribution of data and voice services. In the buffer zone (7am to 9am and 5pm to 7pm) data is being given low priority and many data calls dont work. This would cause decent revenue loss except that most of the people on data plans have a flat rate package so it does not bother the operators.

This is despite the announcement last month about Huawei and Qualcomm successfully completing their IOT with Telecom Italia. Orange and T-Mobile has been trialling MBMS based on TDtv technology but lets accept the fact that it is TDD-MBMS rather than the FDD-MBMS which other manufacturers like Qualcomm, Nokia and Ericsson are (were) actively working on.

I read this blog some days back and it emphasised what I have been saying for years now that there will always be multiple technologies floating around. MBMS could be a starting point for Mobile TV but as the demand grows it will have to be supplimented by other specialised technologies like DVB-H, DMB-T, MediaFLO, etc, etc.
For the time being, rest in peace MBMS.

Mobile TV Technologies comparison


Saw this new book on Mobile TV "Handbook of Mobile Broadcasting".

Mobile TV has been discussed for long time now but its surprising to see that none of the actual broadcast technologies is being actively used. There are small pockets here and there but no proper deployment. Here is UK, Mobile TV is actually TV on demand which is streamed onto our mobiles. Is it much different in other places? I did write a blog earlier titled '2008 may finally be the year of Mobile TV'.

The book mentioned above gave an interesting comparison of the 4 main technologies which is shown above. I would have liked it to expand it slightly by including DVB-SH and S-DMB.

Finally, heard that ALU trying to do some work on DVB-SH. See this.

Qualcomm shows off MediaFLO Mobile TV


Qualcomm Incorporated, a leading developer and innovator of advanced wireless technologies and data solutions, today unveiled the first-ever MediaFLO™ technology demonstration broadcast over the air to an in-vehicle entertainment system. The innovative mobile TV demonstration shows the flexibility of the MediaFLO platform as well as the exciting and unique delivery methods it can enable in a wide variety of scenarios.

The in-vehicle demonstration features a sport-utility vehicle outfitted with two rear headrest television screens with VGA resolution. The MediaFLO receiver, integrated in the rear center console, will receive live streaming television broadcasts on the MediaFLO platform at QVGA resolution. The center console controllerallows users to launch the electronic channel guide, change channels and access optional features of the MediaFLO System.

The MediaFLO in-vehicle demonstration can be seen at the MediaFLO booth (Central Hall, #C2946) at the National Associated of Broadcasters (NAB) show, April 14 - 17 in Las Vegas, Nevada.


MediaFLO enables a rich mobile multimedia experience comprising high-quality video, audio, data and interactiveservices. Since the MediaFLO platform employs a dedicated mobile broadcast network, it does not require direct line-of-sight, unlike satellite-based TV transmissions, and video quality and signal strength won’t be compromised in crowded metropolitan areas. Furthermore, the platform has been designed for superior mobile reception and can operate efficiently under normal driving conditions on roads and freeways.

MediaFLO is a mobile broadcast platform for the delivery of high-quality entertainment and information, including streaming video and audio, Clipcasting™ media, IP datacasting and interactive services. FLO™ is an open, globally recognized air interface technology standardized by the Telecommunications Industry Association (TIA) and recommended by ITU-R for the broadcasting of multimedia and data applications. Invented for mobility, MediaFLO is designed to increase capacity and coverage, as well as reduce costs for multimedia content delivery to mobile devices. More information about MediaFLO is available at www.mediaflo.com.

And the winner is . . . DVB-H


Brussels has now officially endorsed DVB-H as the mobile TV technology of choice in Europe. This means that member states are now required to "encourage" use of the technology, though the commission has no advice as to how to encourage punters to tune in.

In the UK both T-Mobile and Orange are about to launch trials using the competing MBMS (Multimedia Broadcast Multicast Service) technology, which utilises existing 3G networks and spectrum. The technology for that trial is being provided by NextWave Wireless, and CMO Jon Hambidge is dismissive of EU attempts to mandate a mobile TV technology "when [the network operators] spent billions of dollars on their licences MBMS [was] part of that business case".

Note that in an earlier blog I had mentioned that Mobile TV and MBMS will co-exist. See here.

Viviane Reding, EU telecoms commissioner, has made it clear that if companies don't migrate to DVB-H she'll use regulatory measures to create an EU-wide standard.

Background Material:

The DVB-H standard is a recent extension of the DVB-T standard. It is intended to allow reception of television programs with portable and mobile terminals of relatively small size (the H of DVB-H means “handheld,” which indicates the primary type of devices targeted).

In most cases, the terminal will be a mobile phone. In fact, one of the main goals of DVB-H is to avoid the limitation inherent to UMTS of the number of terminals which can receive the same broadcast television program at one time. The main extensions of DVB-H compared to DVB-T are as follows (their use is signaled by specific TPS bits):

• addition of a 4 k COFDM mode, better suited to the implementation of SFN networks of medium cell size and allowing a reduction of the power consumption of the terminal compared to the 8 k mode;
• addition of a longer time interleaving (double for the 4 k mode and quadruple for the 2 k mode), which improves the behavior in case of signal fading and resistance to impulsive noise;
transmission of a given service in periodic bursts by a process known as “time slicing” which permits a subscriber to activate the receiver only during a fraction of the time (5 to 10%) in order to reduce the power consumption, thus increasing the battery operating time;
• the ability to increase robustness by means of an optional additional link layer error correction (MPE-FEC) to improve the reception with an integrated antenna of necessarily very limited performances.

In order to allow the best use of these extensions, TV programs or other broadcast services are transmitted to mobile terminals as elementary streams (ES) formatted as IP (Internet Protocol) datagrams. The use of the IP protocol is, however, different from the one in TV by ADSL using DVB-IP: in DVB-H, the IP datagrams are encapsulated according to the so-called multiprotocol encapsulation (MPE) and then inserted in an MPEG-2 transport stream for transmission (in DVB-IP, it’s the transport stream which is IP encapsulated). This operation consists of encapsultaing the IP datagrams in DSM-CC sections by adding a header and a CRC termination. These sections are then segmented into MPEG-2 transport packets.

In order to realize the desired time-slicing, sections are not transmitted immediately, but are accumulated in order to form records of a maximum size of 191 kb, which will correspond to the duration of the time slice allocated to a service. These records can be represented as a table of 191 colums by a maximum of 1024 rows on which an optional additional error correction called “MPE-FEC” can be applied. This MPE-FEC consists of a Reed–Solomon coding RS (255,191) applied to words of 191 bytes made of the lines of this table. This will produce a second table made of an RS word of 64 bytes for each line of the original table. The result will be a new table of 255 colums by a maximum of 1024 lines which will be read column by column for transmission.

The DVB-H standard can be used in the UHF TV band with usual DVB-T channel widths (6, 7, or 8 MHz, depending on the region) or in other frequency bands (e.g., L-band in the United States around 1.67GHz with other channel widths, 5MHz in this case).

One of the problems with the use of the UHF band for TV reception in a GSM phone is the proximity of the high part of the UHF band (up to 862 MHz) to the GSM 900 transmit band of the terminal (880 to 915 MHz). Taking into account the current filtering capabilities, this prevents in practice the possibility of using the high UHF channels (>750 MHz) in a TV receiver integrated into an operating GSM phone.

The DVB-H standard can in principle use all the combinations of modulation parameters allowed by the standard (QPSK to 64-QAM, etc.) but, given the required robustness of this application, in practice only QPSK and 16-QAM with FEC of 1/2 or 2/3 are realistically usable, which permits bit-rates of 5 to 11 Mb/s in an 8MHz channel (without MPE-FEC correction). The video encoding used will be mainly H.264 with a CIF or QCIF resolution and bit-rates in the order of 256 to 384 kb/s.

Various experiments took place in Europe from 2004 onward to test the technical performances of the system in order to define the characteristics of the network, and to find out the user acceptance and expectations in order to establish a viable business model. The reactions of the test sample have been positive or enthusiastic everywhere. The first commercial DVB-H services started in Finland and Italy in mid-2006.

MXtv or MAXtv


NextWave MXtv(TM) is a breakthrough mobile multicast and broadcast technology that enables WiMAX operators to deliver a broad range of rich and personalized multimedia services including mobile TV, interactive media services, and digital audio for a more compelling subscriber experience. An innovative broadcast solution, NextWave MXtv does not require any additional spectrum and uses existing radio access network equipment providing operators with an entirely new business model to increase revenues and achieve profitability. With MXtv, WiMAX wireless operators can effectively manage their valuable spectrum resources by dynamically balancing bandwidth allocated to broadcast services with on demand services.

So we now have Mobile TV over WiMAX which i personally think is quite good. Unfortunately the Mobile TV services havent caught up with general public yet but the operators have themself to blame quite a bit for this. The pricing is not friendly and then a lot of times, the content is not very friendly. The online portal designers dont understand how to categorise the content so someone doesnt have to browse for 5 minutes to reach their favourite item.

Anyway, this Mobile TV thing is a really good option along with MBMS, TDtv, DVB-H, T-DMB, MediaFLO, etc., etc.


NextWave Wireless Inc. has signed a strategic deal with Alcatel-Lucent over the WiMAX-based mobile TV platform it announced earlier this week.


The agreement calls for Alcatel-Lucent to integrate NextWave's MXtv technology into its WiMAX portfolio, based on the 802.16e-2005 (Rev-e) standard.



The companies also plan to perform a series of interoperability tests with Alcatel-Lucent's commercial WiMAX infrastructure starting in the second quarter of this year.


In a separate deal, Chinese communications gear supplier Huawei also said this week it would integrate the MXtv technology into its own WiMAX networking kit.



The MXtv technology has also been integrated into NextWave's low-power, Wave 2 compliant NW2000 series WiMAX subscriber device SoC. The device is currently being integrated into a wide range of devices with some device availability planned for second half of 2008.


The technology is based on the TDtv mobile TV platform NextWave (San Diego, Calif.) gained access to through the acquisition last year of UMTS-TDD kit supplier IP Wireless (Chippenham, England).



NextWave says its latest broadcast technology will allow WiMAX operators to deliver rich and personalized multimedia services including mobile TV, interactive media, and digital audio. NextWave said that macro-diversity technology is used to improve the broadcast performance over the WiMAX channel.


The offering promises 30fps QVGA and WQVGA content and up to 45 high quality mobile TV channels in 10MHz with channel switching times below two seconds.



Network operators can also dynamically allocate spectrum based on content availability, time of day requirements, user demand, and the availability of live events such as sports, concerts, interactive reality shows or emergency broadcasts.


"User demand for mobile broadcast services is rapidly expanding and we believe that the exciting new applications offered through this alliance will provide mobile operators a unique ability to deliver the key differentiating feature of 4G networks," said Allen Salmasi, CEO of NextWave Wireless.

2008 may finally be the year of Mobile TV


Mobile TV was one of the topics that held a lot of interest in MWC08. Some of my clients i discussed Mobile TV with wanted to wait for MWC to check which direction the wind is blowing. The news seem to be that most of the handset manufacturers seem to be looking at it now.

According to this report in Forbes magazine:

Many Chinese can already catch analog television signals on some handheld devices. The Chinese government, however, intends to use the Olympics to showcase the next wave of digital mobile TV, based on standards developed in China.

Huaqi, a Beijing manufacturer of handheld devices, is planning to build inexpensive, user-friendly portable media players and navigation devices. Four different models, priced around $300 apiece, will debut in June, says Guo Hongzhi, Huaqi's general manager of resource management. Outfitted with 4.3-inch screens, they will also be able to play music and video and will eventually incorporate global positioning satellite data and wi-fi.

Some of the nuts-and-bolts technology, however, is coming from elsewhere. Alon Ironi runs Siano Mobile Silicon, an Israeli firm that makes the specialty TV receiver chips that receive signals encoded using the unique Chinese standards. Siano's chips can receive both satellite and terrestrial signals--an unusual combination that will eventually make the network more affordable, Ironi predicts. For now, that's hardly a concern: The Chinese government plans to subsidize the mobile digital TV service for the first year to whet Chinese users' enthusiasm for the technology.

The Olympics promise to be a picture-perfect showcase for China's digital mobile TV service. Work on digital TV has been going on for several years. Public trials in 35 cities are slated to begin in April. By the time of the highly anticipated Aug. 8 opening day of the games, China plans to be broadcasting digital mobile television to 65 cities throughout the country.

The magnitude of the Chinese mobile market, the largest in the world, with more than 540 million subscribers, means that the summertime experiment could turn into big business.


This would also be a boon for mobile TV around the world. Despite success in countries like Japan, Korea and Italy, which began broadcasting mobile digital TV as early as 2005, the technology has yet to take off worldwide.

There are many problems at present with adoption of Mobile TV. First is the high prices and poor quality:

There is a fast-growing army of ex-mobile TV users in the U.S. and Europe’s major mobile markets. Disgruntled by the high prices, and dissatisfied by the poor quality and reliability of the service, consumers are turning their back on the service in their droves. So much so, in fact, that the number of ex-mobile TV users now outnumber more than two to one mobile TV users in Germany, Spain, France and Italy.

This is the key finding of a survey conducted by M:Metrics, the results of which are published today. By comparing mobile TV usage patterns in January 2007 with those during November 2007 in the UK, Germany, Spain, France, Italy and the U.S. — more than 34,000 mobile users were surveyed in total — M:Metrics found the size of the mobile TV audience had increased by 36 percent. The bad news for mobile operators, however, is that the number of former mobile TV users had grown by a whopping 68 percent.

The second most popular reason for mobile TV disillusionment among M:Metrics’ survey respondents was poor quality and reliability, cited by an average of around 25 percent of ex-mobile TV users across the countries surveyed (ranging from 22 percent in the U.S. up to 30 percent in the U.S.).

The others are more due to technological limitations which will be overcome with time:

Receiver chips must be energy-efficient to preserve battery life--an important consideration in any mobile device. At the same time, they must be sensitive enough to transform even weak TV signals into clear images and function in sheltered places, like garages, and at moderate speeds, such as on trains or in fast-moving cars.

And then the standards:

Clashing standards have slowed adoption. Like many cellular technologies, mobile TV standards differ by region, forming an alphabet soup of acronyms: wireless technology company Qualcomm's MediaFLO in the U.S., DVB-H (Digital Video Broadcasting for Handhelds) in Europe, T-DMB (Terrestrial Digital Multimedia Broadcast) in Korea, and ISDB-T (Integrated Services Digital Broadcasting - Terrestrial) in Japan and Brazil. The standards are largely incompatible.

And ofcourse the business models:

That fragmentation extends to business models. There are "free to air" services, which, like basic TV channels, can be picked up by any device with the right chip or receiver--no service provider necessary. Particularly popular in Latin America, the Middle East and parts of Asia, these channels generally offer the same programs a home TV would show for free. Then there's the paid model, predominant in the U.S., in which mobile carriers provide premium TV shows to subscribers for a fee.

According to Ericsson's Mobile TV Research Study:

Mobile TV use is set to surge due to strong consumer demand, with the service ranked as the number one application users want on their phone, according to a consumer behaviour study conducted by Ericsson and the #1 international news broadcaster, CNN.

The results show more than a third (34%) of respondents ranking TV as the most in-demand application and almost half (44%) of the respondents poised to adopt mobile TV in the next two years.

Key findings also revealed that photo and video messaging look to be set for wide-scale adoption as consumer pricing and functionality improves. 57% of respondents use photo technology to send and receive images on a monthly basis, making it the most popular activity. This trend is mirrored by popularity of CNN International's user-generated content service iReport, which launched in 2006. The service garnered 50,000 submissions, including mobile phone footage and images, from 189 countries worldwide in its first twelve months, driving the worldwide trend for 'citizen journalism' and giving audiences a deeper connection to network news.

According to the report, nearly one in four (24%) current mobile TV users watch daily with around half (52%) tuning in on a weekly basis. At 77%, news leads genre viewing patterns, followed by scheduled television at 48%.


And ABI Research's report:

mobile TV services expand over the next five years, ABI Research sees the total number of subscribers growing to 462 million, driven in large part by the expansion of 3G networks, and flat-rate plans for mobile video. The build-out of mobile video delivery networks and an increase in the amount of available content will also contribute to the market’s growth.

ABI Research sees the Asia-Pacific region as the overall leader in the adoption of mobile video services. The number of subscribers to mobile video services in Asia-Pacific will grow from 24 million in 2007 to more than 260 million by 2012. High levels of penetration will occur in both Japan and South Korea, each a leading market in mobile video services, while China and India will both contribute significantly to the overall total due to very large subscriber populations, even though the overall penetration of video services will remain much lower than in more technologically advanced countries.

“South Korea and Japan will continue to lead worldwide, while some countries in Western Europe will also continue to see strong growth,” notes Wolf. “North America will also see some strong uptake as more services become available in 2008 with the launch of AT&T’s MediaFLO service, the continued expansion of Verizon Wireless’ MediaFLO subscriber base, and the growth of on-demand mobile video services.”


Panasonic announced that it has begun shipment of its P905iTV mobile phones to NTT DoCoMo, Inc.

Combining the design concept of Panasonic large-screen flat-panel TV ’VIERA’ and its high-quality picture technologies, the P905iTV is a sliding handset featuring "One-segment" mobile TV. Adopting frame conversion technology from 15 frames to 30 frames per second enables users to enjoy smooth, vivid and high quality "One-Segment" mobile TV together on a 3.5 inch Full Wide VGA large screen.

The handset employs Panasonic’s original high-resolution technologies, "Mobile PEAKS PROCESSORTM" and "Mobile Double Contrast AI" that achieves a high contrast ratio of 4000:1, enabling users to enjoy vivid and high resolution "One-Segment" mobile TV and motion pictures.
Using "LCD Artificial Intelligence" which adjusts the brightness of a display automatically and advanced system LSI based on "UniPhier" for mobile phone, the P905iTV leverages eye-friendly pictures and electric power saving, letting users enjoy long-time ’One-Segment’ mobile TV viewing and music playing.

Do I hear TDtv again?



BARCELONA, Spain, Feb 12, 2008 (BUSINESS WIRE) -- NextWave Wireless Inc. (formerly IP Wireless) a global provider of mobile multimedia and broadband technologies, today paved the way for handset manufacturers to easily participate in the global market for TDtv by announcing a TDtv Device Integration Pack. Designed to meet the strict cost, size, and power consumption requirements established by some of Europe's largest mobile operators, NextWave's TDtv Device Integration Pack includes a low-power TDtv System in Package (SiP), a complete MBMS software stack, and MediaFusion multimedia client software from PacketVideo Corporation (PV). NextWave's turnkey solution will enable device vendors to deliver TDtv handsets to market in 2008 in support of the TDtv initiative announced today by NextWave, Orange and T-Mobile UK.

"Our TDtv device integration module provides a simple and inexpensive way for device manufacturers to integrate the power of TDtv into their next-generation WCMDA handsets," said Dr. Bill Jones, CEO of NextWave Network Products. "We're confident that a growing number of device manufacturers will support TDtv as mobile operators begin to accelerate wide-area deployments of TDtv systems."


TDtv is an innovative 3GPP MBMS solution that provides mobile operators an opportunity to profitably deliver up to 28 high-resolution TV channels, digital audio channels, and other IP data-cast services to an unlimited number of concurrent customers. By operating on existing 3G spectrum and with the unique ability to support multi-carrier spectrum pooling and network sharing, TDtv represents a breakthrough in reducing the cost of implementing mobile television and provides UMTS operators around the world with a powerful multimedia and advertising platform. Currently, more than 150 mobile network operators in over 50 countries have access to the spectrum needed to deliver TDtv to more than half a billion subscribers.


"When we looked at the available mobile TV technologies, TDtv was one of the technologies that impressed us the most, both from a performance as well as from a market opportunity perspective," said Michael Thelander, CEO of Signals Research Group, LLC. "With spectrum available across Europe and many parts of Asia and with two major operators now moving forward with an initiative, this is a market that handset vendors should take the time to explore."


NextWave's TDtv Device Integration Pack includes everything device manufacturers need to create a TDtv- enabled handset. The Device Integration Pack includes an integrated TDtv System in Package (SiP) measuring approximately 10x10 millimeters, a complete software suite that includes the required MBMS software stack, and TDtv radio access network controller software. The TDtv SiP includes a TDtv baseband chip, RF chip, receive filters and passives, and interfaces directly with the handset's application processor. This low power (active power consumption under 60 mW) solution enables device manufacturers to better meet network operator requirements for sleek and highly-attractive mobile TV handsets with internal antennas, and includes filters that allow for seamless coexistence with existing 2G and 3G services.

Meanwhile in Guardian:

T-Mobile and Orange will today announce a partnership to run a commercial trial in west London of a new mobile TV technology which could allow handset users to tune in to up to 100 channels.


The technology, TDTV, has been developed by US-based NextWave Wireless at its British unit in Chippenham, Wiltshire, and could provide a cheaper and more efficient way to get broadcast TV on to mobile phones. The trial, due to start in late summer, will see several thousand Londoners given either a new handset - made by a far eastern manufacturer rumoured to be LG - or a wireless receiver, no bigger than a matchbox, which will transfer the channels to their mobile phones.


The six-month test will see Orange and T-Mobile share their masts in London and install equipment that will allow them to broadcast 24 high-quality TV channels including several from the BBC and BSkyB, and 10 digital radio stations. It follows technical trials of the service carried out by Orange in Bristol last year. Orange and T-Mobile are also inviting O2, Vodafone and 3 to take part in the London test.


TDTV uses a slice of the 3G spectrum which Britain's five networks spent £22.5bn buying eight years ago and which has so far lain dormant. As a result, TDTV works with the phone companies' systems, making it easy to bill customers.


TDTV is more efficient and has more capacity for channels than other mobile TV solutions. Orange, T-Mobile, Vodafone and 3 are all offering mobile TV through their 3G networks but they suffer from congestion if more than a handful of customers use the service in the same place. TDTV uses a different part of the 3G spectrum and many more users can watch TV simultaneously.


The European Union has proposed using a Nokia-backed standard called DVB-H for mobile TV in member countries, but there will be no spectrum available for it in Britain until the analogue TV signal is switched off in 2012, and the operators will have to pay if they want it.


DVB-H, which O2 tested in Oxford two years ago, can carry only about two dozen channels while TDTV could have up to 100.

Broadcast Views


Interesting article from telecoms.com, i had missed earlier. Mobile TV is one of my pet topics so if you see me not mentioning about some important article then do mention it here.
Important points highlighted below:

As we approach the final quarter of 2007, however, the future of mobile TV is,
if anything, more uncertain. As individual carriers in different markets adopt their preferred technologies, the list of 'standard' broadcast solutions seems to be growing at the same rate as new services are launched.

In Europe, during the summer, the EC finally backed DVB-H for mobile TV rather than remaining technology neutral. In Japan and South Korea, service uptake on existing ISDB-T, and T-DMB and S-DMB, is continuing to build, albeit slowly. In the US, Verizon and AT&T have both selected Qualcomm's MediaFLO solution, which launched in March and Verizon has already gone live.

Meanwhile, BT Movio's, and therefore Virgin Mobile's, DAB solution in the UK folded due to poor uptake less than one year after launch, along with Crown Castle's DVB-H solution in the US.

On Europe, David McQueen, principal analyst Informa Telecoms&Media says: "It is possible to see the logic of support for a single mobile TV standard for Europe. GSM as a de facto standard allowed economies of scale in the industry, and made roaming easier. In theory, therefore, choosing DVB-H, is like getting the whole of Europe to go down the GSM route. Also, you are backing the frontrunner."


But backing a frontrunner that won't arrive in some markets until 2012 seems a trifle premature; at least, so says ROK TV CEO, Bruce Renny: "You have got to look at when this service is going to be available in the UK. I can tell you, 2012 at the earliest when the last of the analogues is switched off. Now 2012 in the mobile environment is a lifetime away. I mean, a month is a long time in the mobile entertainment space, quite apart from five or six years."


A recent report from Dutch analyst house Telecompaper revealed that, although three operators (KPN, Vodafone and Orange) in the Netherlands offer mobile TV, only 1.4 per cent of subscribers has watched TV using a cellphone. In fact, from a list of 22 unique data services, mobile TV was the least popular.


M:Metrics, meanwhile, found that the number of subscribers that watched any commercial programmed mobile TV and/or video, once or more, in a month in France, Germany, Spain, Italy and the UK combined, in the three months ending July 2007, was 2,386,795. It looks like a fair size number, but in reality it's only 1.12 per cent of subscribers.


In a recent strategic report Mobile TV: Broadcast Network Rollouts, Business Models and Handsets, Informa Telecoms&Media predicts the market for broadcast mobile TV devices grew from 0.81 million in 2005 to just over four million in 2006. These devices are expected to find their way into 12.3 per cent of new handset sales by 2012, representing an expected market of 178 million phones.

The ITM report states that an inflection point is expected to occur in 2009 as network rollout and device availability allow for the market to reach some level of critical mass. Informa goes on to predict that there will be 335.6 million broadcast mobile TV users worldwide by 2012, up from a mere 12.1 million expected in 2007, with an inflection point expected in 2009-2010.

According to Informa, a number of possible scenarios emerge that could enhance or dilute mobile operator strengths in the mobile TV value chain.
First, the 'discrete' business model, where the MNO chooses to provide TV services only over its own cellular networks, or via network optimised solutions, with no other broadcast network interaction. Second, the 'principal' business model, where the MNO is lead player in the broadcast TV industry, which includes some level of interaction with broadcast network services. Third, a 'converged' business model, where the MNO and others in the value chain work in cooperation to take advantage of the complementary nature of cellular and broadcast networks. And fourth, the 'bypassed' business model, where the MNO is bypassed altogether by a broadcast network operator in providing mobile broadcast TV, but may still provide an uplink.


There are advantages and disadvantages that go along with each of the above scenarios. The discrete model will appeal most to those operators that have already invested in a 3G network, since it requires minimal further investment and it ensures that the MNO retains full control of the service and therefore will derive the optimal revenues.


Not surprisingly, most of the noise coming from tech vendors at the moment surrounds rolling out new kit as part of a broadcast solution. Detractors of the discrete model point out that a unicast offering is limiting and would have a detrimental effect on other 3G services in the cell. Therefore, they say, operators need to embrace either a principal or converged model.


"We already have mobile TV on networks with 3G. So if you have invested in a 3G network it is very cheap to deploy a service," points out Alban Couturier, mobile TV product manager, Thomson. "But for users the data cost is high. Which puts people off. Using DVB-H you have lots of costs to deploy, but new customer additions are cheap. Once you reach critical mass, the costs become very low. You can't have that with 3G," he says.

One firm only too happy to be involved in Vodafone's discrete model is British Sky Broadcasting. Steven Nuttall, director commercial group, British Sky Broadcasting, speaking on a recent Telecoms.com webinar, outlined how pleased he is with the pace of mobile TV in the UK: "A year or so into running a service, we've got several hundred thousand customers, paying real money to use it. We've got millions of people using more general mobile services, many of which are video, so I don't know at what point you would say that video is a mass market. I think it is reasonable to say that at a minimum we're pretty close to that point already."


ROK TV's Renny says his firm offers a discrete solution for carriers that have yet to rollout 3G networks. "There are 100 million people worldwide who have signed up to 3G. It sounds impressive, but that's about three per cent of the global mobile market. A 100 million uptake across a three billion market place is, in anyone's language, niche."


ROK offers the ability to stream video over what Renny says are vastly underused GPRS networks. "I think linear TV over mobile phones will prove very popular indeed. The question is how many people will be willing to pay a subscription service to receive linear TV on their mobile phone? Particularly, when you get all that at home for free. The notion of 'build it and they will come' is flawed," he says.


Renny points out that TV on the mobile is not the same as broadcast TV. "It isn't viewed in the same way, it is delivered through a different vehicle and it is a different animal completely. Broadcast TV available on mobile phones will prove popular, but only as a value add in a general mobile bundle. As a stand alone subscription service it will have very limited uptake indeed," he says.


Another firm that advocates taking full advantage of existing resources is IPWireless. The firm's TDtv offering uses the 5Mhz of UMTS TDD spectrum that the majority of 3G operators across Europe have at their disposal. Thanks to the 3GPP specified MBMS (Multimedia Broadcast and Multicast Services), operators can take an existing 3G network and render it multicast, rather than unicast.


The firm had a multi-operator trial in the UK city of Bristol last year. CMO Jon Hambidge told MCI the technology matches DVB-H and MediaFLO in terms of available channels and he is confident that an operator in Europe will go live with the service sometime next year.


"A lot of people are questioning the need for broadcast services," says Hambidge. "One of the reasons is that they are very expensive. I've seen some economic analysis on DVB-H showing that it has a very hard time breaking even down at a ??????5 type level. I think the economic analysis we've seen shows that TDtv, for an MNO, is going to breakeven somewhere around a five times lower price point. So it really keeps mobile TV as a 3G service."


While ROK's Renny may think the 'build it and they'll come' scenario is flawed, Qualcomm would disagree. The San Diego firm's subsidiary MediaFLO USA rolled out its mobile TV solution across America going live in March 2007. Subsequent to that, Verizon launched a service on the network, and will soon be followed by AT&T.


"There are a lot of challenges with that pure wholesale approach," says Omar Javaid, VP of global strategy and business development at Qualcomm. "The interesting thing about mobile TV is that it is a converged service and there are so many different industries involved. When the telecommunications industry is looking at it, they're looking at it primarily from an infrastructural and technology approach, and what tends to get missed in that equation is the whole content rights issue."


Javaid highlights a common assumption that the free-to-air broadcasters will simply provide their content for mobile TV platforms. While the content providers will maintain that the rights for free-to-air broadcast do not extend to this kind of platform. So the content rights need renegotiating, and they're not free. "When you work out the match it becomes much more expensive. Both from a wholesale perspective and then subsequently a retail perspective. I don't think it is impossible to do, but somebody ends up having a pretty marginal business," he says.


Each of the networks under consideration for delivering mobile TV has their own advantages and drawbacks. The most recurrent themes are the ability to provide a one-to-many broadcast topology, network and device costs, reception quality, regulation, spectrum allocation and efficiency, handset manufacturer and network vendor support, and technology fragmentation in different geographic regions.


Broadcast networks use spectrum allocation and one-to-many broadcast efficiently, unlike many of the mobile TV point-to-point offerings available over cellular networks, even 3G, which put the network under enormous strain. The broadcast network technologies, such as DVB-H, MediaFLO and DMB, are far more efficient in terms of time and bandwidth usage, which means they are more cost effective, but they do not enable fully interactive content, something that the cellular networks can provide. However, fragmentation of the market into different technologies using different frequencies is a major risk for the nascent mobile broadcast TV market.


For now, the most sensible plan looks like the one advocated by Anders Kalvemark of Ericsson: "I think we will see various types here. Our main strategy is that the operators will have their own 3G networks and then they will enable broadcast capabilities, which could be NGN, so the evolution of 3G. Dedicated broadcast networks will probably arrive, they already have in a few countries, but it is obviously a large investment. I wouldn't be surprised if we saw a consortium of operators coming together to set up these types of network."


Alban Couturier of Thomson: "3G operators should leverage existing services by offering a hybrid of services. They should offer the most popular channels over broadcast, but they should offer the long tail over 3G because it is ideally suited for video on demand."


Of the four models described by Informa Telecoms&Media, it is possible that, for the longer term success of the mobile TV industry, cooperation and understanding between the players in the value chain, providing a converged solution will ensure the best possible experience for the customer. This allows broadcast media to be combined with, and used to complement, cellular communications to enrich the user experience and encourage interactivity. There will undoubtedly be problems with implementing this scenario with so many large brands fighting turf wars. But, if the industry can overcome its natural competitiveness in this instance, it will allow the delivery of new revenue sources for all in the value chain.


However, mobile operators currently offer mobile video and TV services over their own 2.5G and 3G networks and the advent of broadcast networks in the mobile space will undoubtedly affect their stature in the ecosystem. Although much is made regarding operators providing a return channel for interactive services, a potential future scenario could be one where even the provision of this channel is taken away as return channels become more prevalent through the broadcast network, weakening the position of the mobile operator in the mobile TV value chain.


In contrast, the migration by the operators to next-generation 3.5G and 4G networks could also negate the need by the operator to involve broadcast networks in the provision of mobile TV as these will allow for greater speed and bandwidth to provide a more cost-effective mobile TV offering.


Back in 2006, Virgin Mobile's head of mobile TV Paul Coombes told MCI his firm was launching using a DAB solution because it was "available". Right now, that choice seems like folly. Not surprisingly, neither BT nor Virgin wanted to comment for this piece. In fairness, there really are no sure things in this industry. But right now, trying to back a winning solution looks more like an expensive gamble rather than a sound investment.

Mobile TV via Satellite


A heading of news article yesterday read: "European mobile operators are looking for economic ways of launching broadcast mobile TV services directly to handsets". This made me wonder, if there is a strong case for Mobile TV via Satellite?

Couple of days back, 3 Italia reported that it had 719,000 people using its DVB-H service by August 22, which is about 9.4 percent of its 7.68 million customer base reports Dow Jones in Italian. The figure is a good sign—at the beginning of June it was 600,000 and back in March it was 250,000, or about 3.7 percent of the subscriber base. So this proves that some people are using Mobile TV if available.

The only popular satellite Mobile TV i am aware of being used practically (please correct me if you know more) is the S-DMB being used in Korea.

According to a report in Moconews, currently some 7 million people in S. Korea are watching mobile TV--that equates to one in every seven residents of the country--but none of the operators offering DMB services has yet to make any money. Each of the six terrestrial DMB operators has piled up an accumulated loss of between $22 million and $33 million. The only mobile TV operator that charges for its service is SK Telecom-owned TU Media, which offers its DMB service over a satellite-based system (S-DMB). It has 1.2 million paid subscribers, but TU says it needs at least 2.5 million to break even in operation. That’s before it can even start to recoup its $435 million investment in satellites and networks.

The European Space Agency (ESA) has joined the DVB-H party by funding development of technologies for broadcasting TV to mobiles via satellite. ESA has called its standard DVB-SH (Digital Video Broadcast - Satellite, Handheld) and envisages using satellites to send out video at 2GHz to 4GHz (S-Band). Terrestrial repeaters would be used to give indoor coverage. Eutelsat has commissioned a new satellite to be launched in 2009, with the intention of broadcasting DVB-SHb - though it's hedging its bets by claiming it's for multimedia distribution rather than any specific technology or application. Much of the technology needed by DVB-SH doesn't yet exist, so the ESA will be issuing invitations to tender (ITT) for companies that want to have a go at developing them. First up will be a mobile chipset capable of receiving and decoding DVB-SH version b signals. The ITT is due to be published in the next few months.

Finally i found a good report on BetaNews detailing the pros and cons of Satellite Mobile TV:

It's an ambitious idea, and it's not nearly a done deal. But yesterday, a proposal was introduced before the European Parliament for a timetable by which the EU would select a few choice service providers, for the precious and narrow spectrum it will be making available for the entire continent. It will require the consent and cooperation of all 27 member states - something the EU rarely gets even with less ambitious proposals.

Here's what it means: Last February, the EU established two small chunks of radio spectrum - 1980-2010 MHz and 2170-2200 MHz - as reserve space for future MSS broadcasting. Under normal EU law, member states would each have the right to select their own service providers for satellite TV and radio service for their respective countries. In fact, if the EU were to change its mind now and do nothing, that's what EU states would do next.

But there's two big problems: First of all, no single EU country is very big, geographically speaking, compared to the whole of Europe. A satellite signal covers a very broad portion of the Earth, so any service provider licensed for, say, France could probably have its signal picked up in southern Finland. Simply put, the laws of physics dictate a wide coverage area that technology cannot circumvent...unless every mobile TV receiver in Europe were custom-built for each member country. (If you're thinking like a manufacturer of DVD consoles, you might not be too opposed to trying that.)

Even if France's signal and England's and Bulgaria's and all the others could be picked up everywhere else - which, if you think about it, will be the case anyway - Bulgaria's service provider wouldn't want its signal overlapping England's. And that leads us to the second big problem: There's not enough MSS spectrum available in the 2 GHz band to go around.

So the European Union is stepping in, or at least attempting to. But in order for member states to allow it to do so, it has to formally present its case to those states for why it has the authority to do so. Imagine if, under a different style of US constitution, in order for the federal government to make its case for regulating the public airwaves, it had to get all 50 states' consent to giving up their own rights to do so individually.
Thus a large part of the EU proposal yesterday explains - as it must do under European law - why it's claiming the authority to propose a national selection process for MSS providers.

For its claim to qualify as valid, it has to meet two tests under the EU constitution. First, the claim must meet the Subsidiarity Principle: essentially, that the nature of the job at hand means it can be performed better by the EU than by all the 27 states acting independently. In other words, the EU has to prove it can do the job not because it's better at these sorts of things, but because the problem at hand makes a single body better suited to the task.

Here is where the EU has physics on its side: Satellite signals cover broad territory, and states' boundaries do not. "Selection and issuance of rights over the same spectrum to different satellite operators in different Member States would prevent satellites from covering their natural footprint," the EU proposal reads, "which by nature covers a large number of countries; it would risk fragmenting the satellite communications market and eliminate the natural advantage of satellites compared to other modes of communication. The mobile character of the services involved also means that citizens travelling in the EU should benefit from the availability of such services throughout the EU."

Second, the EU's case must meet the Proportionality Principle. This means it can't claim more authority than it needs to do the job...and once the job is done, it steps out of the way. In other words, it can't appoint a permanent commission like the FCC.

In making that part of the case, the EU goes on, "The proposal will create a mechanism for coordinating the selection and definition of certain conditions to be attached to rights of use of spectrum. It will not touch upon the right of Member States to grant the authorizations to use the spectrum or to attach specific conditions applying to the provision of services in areas which are not harmonized. Member States will be closely involved in elaborating the details of the selection procedure."

Here is where critics say the EU's case may fall apart. In order to win the authority to drive the MSS adoption process, the EU is limiting itself to driving the selection process for prospective service providers. Once that job is done, it's leaving it up to member states to apportion per-country licenses to those companies, for channels which the EU would already have selected as well.

On the one hand, it doesn't make sense. In order to sell its plan, the EU is leaving open the option for member states to deny licenses. But assuming a state does so, how could it block the reception of a signal from a service provider whose license was denied? That might take a technological solution...which brings up the whole "per-country" manufacturing option for MSS receivers again.

On the other hand, only such a hare-brained scheme might just work, because member states don't want to be perceived by their citizens as ceding any part of their authority to a federal institution. Giving them the right to say "no" could be a kind of ceremonial concession, not unlike the establishment of a constitutional monarchy where the monarch is essentially a face on a coin - which is a state of affairs not unfamiliar to member states.

"Since industry so far could not agree on a single standard for mobile TV, commercial launches of mobile TV are delayed," reads a statement from the EU's central authority in Brussels last month. "Europe's competitors, most notably from Asia, have made significant progress - partly due to state intervention - and Europe risks losing its competitive edge unless sufficient momentum is achieved. This is why there is a need to develop a 'blueprint' for mobile TV in Europe."

'3' starts MBMS trials


The mobile operator '3' has again taken a major step forward by starting Mobile-TV trials using Multimedia Broadcast Multicast Service (MBMS). The trials are in conjunction with Ericsson. The following from the press release:
3 Italy uses DVB-H for its Mobile TV offering. However, MBMS is being developed under the auspices of the global 3GPP standards body.

MBMS uses existing 3G networks and spectrum for content delivery, building on existing infrastructure. To deliver MBMS, upgrades are made to the existing network as well as content and broadcast servers. 3G mobile phones with support for MBMS are expected to be available in 2008, said the company.

MBMS is a different approach to Mobile TV combining both broadcast and unicast shows (though multicast is more accurate). It also gives consumers opportunity to interact by voting, sending messages, accessing downloads of related content and special promotions from advertisers.

"MBMS as part of the 3G evolution is an attractive technology not only because of its flexibility and efficiency, but because it's quick and easy to deploy and leverages existing infrastructure," said Kursten Leins, Strategic Marketing Manager - Multimedia, Ericsson. "MBMS allows an unlimited number of users to watch the same mobile TV program at the same time in the same area, as well as enabling valuable user interaction with advertisements, campaigns and programs."

"3 pioneered 3G in Australia, so it was a great opportunity to see the country's first MBMS technology trial run on Australia's first 3G network," Leins added. Since the MBMS signal can be pin pointed to specific geographies, it's also possible to broadcast different mobile TV programs to different areas, giving a locally-specific customer experience and also providing highly targeted mobile advertising opportunities.
"We are very happy with the trial - the technology worked well and apart from delivering a good customer experience, it's extremely efficient in terms of network traffic and capacity, and provides new levels of customer involvement with their programs," said Michael Young, Director Technology & Services, 3 Australia.
The technical trial was held in 3's Sydney Head office over 6 weeks and run by Ericsson who developed the trial system. Using four specially designed prototype handsets, Ericsson also installed equipment to simulate the content and broadcast servers on a section of 3's network so the customer and network experience could be seen.

"The trial has been very interesting, and we'll continue to work with Ericsson to keep a close eye on the technology and the handsets to support MBMS as they develop," Young added.
