Mobile TV will present new challenges to the consumer when selecting their phone and service provider because changing from one provider to another could result in the loss of their mobile TV service.This model might work where itin is the case of CDMA Additionally, the other way around. the recommendation is that if two TVmobile networks follow the same technology then the consumer should be allowed to shift from one network to the other using the same device. Both these issues are going to be difficult to solve and accountability will be a problem. The other factor is the cost of the device; for instance a typical mobile TV receiver requires good processing power for H.264 decoding, a decent LCD screen and proper battery backup. In India phones retailing at over $250 USD are more likely to meet these requirements,andthen youhave toadd TV components. the cost of the mobile someTV mobile handsets Currently, retail at $425. If there are to be volume sales then the devices have to be The other two possible areas cheaper. forTV mobile could be PCs / notebooks with USB dongles or inbuilt receivers and in-car receivers with or without Aftermarket devicesDVD players. enablingTV mobile are expected to be a good market. However there could be a problem with pay channel management as the return channel is not as straightforward as it is in the TV receivers. case with mobile phone Conclusion Spectrum allocation, the licence, and the business model between broadcaster and operator may be the first hurdles, but the real challenge lies at the consumer end in terms of the device and the kind of service that will be offered.

The summary of the set of issues that surround the recommendations are that telecom operators feel their existing licence should cover them for mobile hand feel Broadcasters on the other TV. that the current licence for broadcasting TVdigital should coverTV mobileas well, and that the telecom operators should have to get new licences to TV. provide mobile In India operators are launching TVmobile from a GSM perspective with streaming as an option. From a broadcasting point of view there exists a choice of standards from MediaFLO, TRAI has to DVB-H. ISDB-T T-DMB, left this decision to the broadcasters/ operators. Nevertheless, stakeholders in the eco-system have deemed DVB-H to be a good choice for India. discussions in the industry Currently, all revolve around the above issues. Assuming these can be solved, other challenges remain such as the cost and type of the device, and the service that will be successful in India. The current Doordarshan DVB-H TVmobile service in Delhi provides around 8 free-to-air channels. When the new services are launched it is expected that prime content, especially from other broadcasters/telecom operators, may not necessarily be free- to-air; payment models have a definite impact on the traction forTV mobile services. Sport, especially cricket, enjoys mass appeal and consumption in India while other content such as business and financial news have more segmented appeal. This scenario is a little complicated because first you have to pay extra for As it stands today TV handset. a mobile from an eco-system perspective, the device will be enabled with software

In January 2008 the regulatory Regulatory Telecom authority, Authority of India (TRAI), gave its TV recommendations for mobile to the Ministry of Information and Broadcasting. Since then a lot TRAI has been said about the recommendations and how they affect the players in the industry. The salient features of the recommendations are: The service provider should have • the choice over which broadcasting technology is used – providing the technology is approved by a recognised standardisation body. • Handsets provided by an operator should be compatible with other operators that use the same technology and standards, enabling users to migrate. only is transmission Terrestrial • allowed for the time being.

Having always taken place in Dublin, the DVB World conference moved to Budapest this year, with almost 250 delegates from

across the world gathering for three days in March for what was broadly agreed to be the best edition yet of the event. The DVB - SCENE 13 keynote address was delivered by European Union Commissioner Viviane Reding, who took the opportunity to express her support and appreciation of the work of the DVB Project in the creation of open standards. Her presentation focused on mobile TV, the opportunities for DVB technologies worldwide, and the digital dividend strategy of the European Commission. Dominant themes to emerge over the course of the conference included: the challenges of managing content in our increasingly networked lives and the role DVB-CPCM can play; the implications for the broadcast industry of DVB-T2; the growing role of IP in content delivery, whether through ‘traditional’ IPTV or Open Internet television; and the importance of clarity in IPR issues for the implementation of all DVB standards. Lively discussion, both inside and outside the conference room, was in evidence throughout the course of the event.
