Information:
Before Olympic Games, 6 olympic cities including: Beijing, Shanghai, Tianjin, Qinhuangdao, Qingdao, Shenyang, and other two cities Guangzhou and Shenzhen, will launch terrestrial digital TV broadcasting. Each city plans two digital channels, one for CCTV high-definition programs, another for CCTV and local analog programs. CCTV means CCTV-1 and CCTV news channel, and local provincial city programs, at the same time this channel also covers local bus mobile TV, from non-national to national standard system transition.

It is important to transmit information by digital TV as Chinese computer penetration rate is not high and network bandwidth is not very developed In addition, there are more then ninety million farmers, most of them especially in mountainous areas. They are not used to use computer, and even they cant afford to buy computer. TV is more common than computer. So digital high-definition TV will meet their real demands.
