  • Foundation before Bob addresses use cases and deep dive Mobile network operator perspective
  • Many operators are using 3G network to deliver video but it doesn’t scale well. There are still plenty of capacity on 3G network because there is not much application but some operators will be out of 3 G capacity in a few years. There is a desire for entertainment but when people asked whether they would like to watch TV on a mobile phone they say no. Saying there is a customer demand is a fallacy.
  • The reception of the service on mobile phones must be ensured indoors and outdoors. Trials have shown that a significant proportion (40% to 50%) of usage of mobile TV is actually generated at home. It has also be found that significant usage is generated in the office. TV Channels are encoded at 300kbps Audio is encoded at 50kbps Good offering should be 25 TV channel and 10 radio channels The most popular programs are news, sports and comedy. It is mostly because they can be packaged into segments of 5 to 10 minutes. However, in korea in one of the most developed mobile TV market it has been shown that drama (30 minutes or so) are the most popular!. People don’t seem to like truncated content Also music is popular but more as a background versus a visual-oriented activity.
  • In the UK only the DAB spectrum is available The analog cut off should make some spectrum available There is some effort by the european community to standardized spectrum throughout europe but it will be tough. Some countries may not accept Qualcomm and may impose DVB-H or T-DMB In some european countries (Germany being an example) the regulator imposed that the distributors of service would not also manage the service platform
  • Early to assess which one will dominate Some are missing T-ISDB in japan and a little bit in brazil Many trials and a few deployments. There are three categories: terrestrial broadcast: most straightforward, requires a lot of spectrum and initial investment is high Satellite: DVB-H, and S-DMB, initial large coverage but needs many repeaters, also need frequency Cellular broadcast: seems nice but it has a major drawback in the sense that operators would need to dedicate part of its frequency resources to broadcasting services instead of unicast service. The 17-67km cell size of DVB-H is actually a little bit theoritical as the 40 to 60km for T-DMB (it really depends in which band you operate) Trials around europe in Italy, Germany, … have shown that the average radius Urban: Suburban: Rural: Emitter 3.5 6 8 # Repeater per emitter 4 1 0 It is obvious that the possibility to reuse cell site is crucial. The number of site for the same population vary greatly based on the population density and distribution in the territory: For a similar coverage you would need about twice the number of emitters and repeaters in france than you do in the UK. There are also great variation in term of CAPEX for transmit power a low power emitters can be about $70K while a high power emitters can be as high as $500K A rough estimate – 80% coverage of france would be a least $500M and maybe $250M for the UK. T-DMB is a derivation of DAB. DAB is used in the UK. T-DMB is a narrow band solution. The channel are narrow – 1.5Mhz which allows for 1.1 Mbps or so. I operate a low frequency and can reuse DAB emitter. It is usually a cheap solution to deploy. Only 3 emitters were necessay in Seoul in the band III, and only 4 high power sites were necessary in the L band in germany to reach out Berlin MBMS: Plusses: 3 G network optimization, no regulatory complexity, limited investment Minusses: limited capacity for broadcast and late market availability. MediaFlo: used by Verizon Vcast – trialed in a few places Sprint, T-Mobile, AT&T -- operates in 700Mhz DVB-H ----- Modeo L band – 1.6Ghz DVB-h ---- Hiwire UHF 700Mhz
  • Cost is a big issue. The cost of adding DVB-H , TMDB or any other technology has to be added to the cost of the phone and then most likely subsidize by the operator The cost are in three areas: HW: DVB-H chipset and radio element SW: end to end sw Integration: integrating DVB-H into the cellular design and adapting handset form factor The cost will be anywhere from $100 initially to potentially $40 after 10 years or so. We estimate that the subsidies constitute the majority of the annual cost of operating the network above 50%. Multistandard chipset – different bands – different protocol ---- OTT vendor iPhone with Wi-Fi Archos is planning to add DVB-H to its devices Nintendo has a ISDB-T (integrated service digital broadcasting – terrestrial) on the Nintendo DS
  • Italy has two DVB-H networks
  • Outside South Korea it is the only T-DMB system deployed. It was done in 2006 just before the soccer world cup. Was initiated by a start up called MFD or mobiles Fersnsehen Deutschland. MFD developed the mobile broadcast platform. In particular it sources the content for the platform, ensures the daily service operations, implement evolutions in the service offering, defines the hardware specifications and decides on the electronic service guide and conditional access systems. MFD has partnered with T-Systems for the network infrastructure and with Irdeto for conditional access. T-DMB is most likely not way to go but the business model is of interest. It gives small operator an option to deliver video. There are only a few channels available , but delivering video in a “radio” band is much cheaper than DVB-H or MediaFLo MFD has only 1 channel of 1.5Mhz which equates to about 1.1 mbps Debitel is a small MVNO but it has about 9million subscribers mostly in germany. DVB-H is actively promoted by four mobile operators: vodafone, t-mobile, o2 and E-plus have formed a consortium to set up a DVB-H network in germany. This consortium is expected to influence technology, regulatory and business choices around dvb-h and also speed up the allocation of resources. MFD is a little stuck because it is too small. The options are Getting more frequence VHF (similar to band III) , UHF or in the L-Band --- more programs and better coverage Obtain a uhf frequency to roll out dvb-h: the main benefit would be to greatly increase the number of channels in urban areas but that would imply that mobeil operators are willing to partner with MFD for the set up of DVB-h in Germany Developing this strategy require MFD to focus on a number of issues: It will need devices supporting multiple bands and multiple mobile broadcast standards It will need a common conditional access system for T-DBM and DVB-H A common ESG is also needed so that the user interface is the same whatever the delivery technology is Some developments on the platform side will be required to support the delivery mechanism of both T-TDM and DVB-H It will need to agree with the operators to offer them personalised branding and channel packaging MFD strategy is not limited to cell phone. It has also work with car companies (Audi, BMW, Blaupunkt and Bosh) for in car receiver.
  • Japan and South Korea in early 2002 started to offer video over 3 G network – it was unicast South Korea 3G network was been maxed out and the country decided to build a mobile broadcast network. TU Media – a subsidiary of South Korea Telecom (which owns 30%) - own and operate a S-DMB network $100 million to buy, send and build operation center for satellite $250 fillers and restransmitter $100 broadcast center and other S-DMB operate at 2.6Ghz and T-DMB operate at 200Mhz The handset are pricey $600 to $800. The issues are the same as 3G but in general satellite phone are bulkier. WHAT DRIVES MOBILE TV IS THE POPULARITY OF TV DRAMA. THE INABILITY OF TU MEDIA TO GET A LICENSE TO BROADCAST the dram from the three free to air broadcaster is a major issue. Also, the structure if the terrestrial market in Korea, which is composed of several regional broadcasters, each with its own discrete footprint – makes it difficult to arrive to an agreement for S-DMB broadcasts terestrial content. Each regional broadcaster customized around national feeds with local content and S-DMB is unable to adjust on a regional level because its footprint is national. The result has been a launch that exclude content from the three largest broadcasters in the country and a lineup that onluce include cable content and terrestrial rerun. In term of content News, sport and comedy are the most popular based on survey but what the Korean deployments show is that drama is even more popular.
  • Operated by KT Telecom and LG Telecom and a collection of local broadcaster Struggle with business model … The regulator refuses to allow a mobile operator to charge for services in the 200Mhz because the content is mostly a simulcast of free to air content from the 3 major networks. The government sees T-DMB as a broadcasting issue and not a telecommunication issue. They need more content Operate in 200Mhz VHF
  • Cannibalitzation of IPTV? I don’t think so. Differentiate mobile TV as a pure entertainment offereing, not an extension of mobile services. There is some play to be done with perception. For example thte is a danger to bundle mobile TV into the monthly bill as data services.

    7. 7. Technology Options Broadcasting technologies landscape – DVB-H standard gains momentum Broadcasting technologies – key facts Out of the large range of cellular, terrestrial and satellite broadcasting technologies, some of them are emerging as standards in different regions. 716 to 722 MHz, 698 to 746 MHz 174 to 230 MHz, 470 to 862 MHz 2.6Ghz VHF band III 1,452 to 1,492 MHz VHF, UHF, L-Band Frequency CAPEX MPEG, IP IP IP MPEG TS MPEG TS, IP Transport stream 2-10km 2-3 km 3-700km 40-60km 17-40km Cell Size 50-70 3 9-27 3-5 60 Channels/128kbps Time division multiplexing Time slicing Bandwidth Shrinking Bandwidth shrinking Time slicing Power Reduction MPEG-4 Up to 11.2 Mbps USA MediaFlo Media Forward Link Only MPEG-4 Up to 0.38 Mbps Europe, South Asia MBMS Multimedia Broadcast Multicast Service MPEG-4 Up to 2.3 Mbps South Korea, Japan S-DMB Satellite Digital Multimedia Broadcast MPEG-4 Up to 1 Mbps South Korea T-DMB Terrestrial Digital Multimedia Broadcasting DVB-H Digital Video Broadcasting Handhelds MPEG-4 Up to 11 Mbps Europe, USA, Australia Video Codec Download Rate Region
    8. 8. Technology Options Mobile TV devices Outstanding issues The challenge here is to find the balance between device cost, performance, form-factor and style depending on the target customer segment. Battery Technology and power management are two crucial aspects to determine the success of Mobile TV. Integration of new DVB-H, DAB or DMB tuners and channel decoders represents a significant challenge both in terms of energy consumption and components costs. Application processors, RAM memory, GPS chipsets, large and high resolution colour displays are vital for high quality of service and end-user acceptance. Ease of use and large choice of different mobile TV ready handsets are essential for the momentum market take-up
