NTT Docomo releses Digital tv Cell phones

Japan on Saturday began to watch digital television broadcasts on mobile telephones, in a highly anticipated service that could lead to a new genre of TV programmes.
Mobile operators have lined up agreements with television networks to develop the service. NTT DoCoMo has tied up with Nippon Television and Fuji Television. DoCoMo's main rival, KDDI, AU, has forged a partnership with TV Asahi.
Japan is a frontrunner in the new technology, popularly known as ‘One Seg,’ after ‘One Segment.
Japan's mobile TV service is not the world's first South Korea, Britain and several other nations offer a similar service, although with different technologies. Mobile users in some parts of the United States can also tap into digital broadcasts.
But the new service in Japan, which is free, will potentially reach the broadest market yet through the country's terrestrial digital broadcast system, which relays images through the air via TV towers, not satellites.

It also uses broadcasting air waves, rather than an Internet connection, to relay streaming video.
