Mobiles & Broadcast TV

The wireless industry is betting that TV On Mobiles would be feasible. They're not talking about just downloading or streaming on-demand videoclips to your phone. Efforts are afoot to broadcast TV programming nationwide to a new generation of mobile phones that can tune in, just like an at-home TV. Despite the massive investments made in upgrading networks to offer such multimedia content as videos and music, they are insufficient for the job. These are designed for two-way, on-demand access. To broadcast programming on such networks would require that each show be sent to each subscriber separately said to be an impossibly time-consuming and expensive proposition. As It's very difficult to offer high-definition TV on a handset through existing networks, several initiatives are under way to achieve just that, a separate wireless network built specifically for one-way multimedia broadcasting.
Qualcomm,is betting on its vision for mobile broadcast TV, making it to act more like a cable company, building i its own content-delivery system, consisting of an entirely new network of wireless transmitters, on airwaves paid for by the company. Customers need a new receiver - also built by Qualcomm - that manufacturers will have to incorporate into future phone models if they want their customers to be able to receive such broadcasts. Finally, the company is negotiating airing rights to programs from major media outlets. Qualcomm hopes to sell the service(offering 15-20 channels of real time broadcasts on a wholesale basis to wireless operators, who would provide it to their subscribers as a complement to their own mobile video services. The display on the mobile phone shall be at 30 frames per second in HD resolution, on par with standard TV. That is twice the frame rate of Verizon's current VCast high-speed video service, with three times the picture quality. "clipcasting" with which uers can select content they would like pushed automatically to their phone and replaced when new installments are created, much like a podcast would also be supported. As usual, the testing ground for such a dedicated multimedia system is in Asia. Korean operator SK Telekom currently offers a wireless multimedia service using a satellite-based adjunct delivery system called Digital Media Broadcasting. A similar system has been operational in Japan for years. Nokia’s Digital Video Broadcast-Handheld technology is being tested across Europe by several wireless carriers and in the United States by partner Crown Castle Mobile Media. Content & Programming are the key to the success - Qualcomm is aggressively lobbying such well-known brands as ESPN, MTV, Comedy Central and CNN to include their content in the service.
