TV Large-scale promotion of the curtain, the next two to three years begin broadcasting terrestrial digital TV programs from the Beijing city

Olympics 8 during the expansion to 333. However, the terrestrial digital television in the end the controversy over what mode of operation still continues. Experts pointed out a number of cable digital television broadcasting sector copy operation mode of practice, is not suitable for receiving terrestrial digital television fixed service on a broader population. Terrestrial digital TV must be based on public welfare, in the mobile receiver can try commercial business operations.

Must be based on public welfare

2.5 billion of funds to support the development of terrestrial digital television, which showed that in the terrestrial digital TV must be led by the state. Experts estimate that digital terrestrial television coverage about the country needs 3.0 billion -40 billion, state-sponsored 2.5 billion funding gap following the commitment by local governments.

Reporter learned that throughout the broadcast sector, 25 billion of the funds are used mainly to purchase transmission equipment, transmission equipment and set-top boxes, terrestrial digital television sustainable operations must rely on others to maintain the commercial means.

After the dust settles in the standards war, the terrestrial digital TV business model caught up in a commercial or public welfare debate. Some experts claim that commercial operation of terrestrial digital television is a matter of time, only commercial terrestrial digital TV operators is large scale development to go way out.

According to report, the United States, Japan, Europe and other countries and regions in terrestrial digital TV operators does not arise in the so-called commercial, public interest is the terrestrial digital television is all about.

Institute of Communication University of China Professor Zhou Yanfu ad told reporters that at present the country has already been launched terrestrial digital TV programs in 32 cities, although they are mainly to public service, but will charge a subscription fees.

She explained that an example of Zhuzhou, Hunan Zhuzhou Zhuzhou terrestrial digital operations by the sound of screen wireless digital TV Network Limited (referred to as Voice-screen wireless) to do, sound screen radio broadcasting industry in Zhuzhou, a wholly owned subsidiaries. Initial installation fee they charge to the user 500, subscription 15 yuan / month, which is almost Zhuzhou cable television fees.

Reception area in a fixed mode of operation used to apply cable is basically a digital TV.

Coverage is the key Currently impeding the development of terrestrial digital television is not the business model or profit model. Tsinghua University, digital TV transmission technology R & D Centre Professor Yang Zhixing told reporters, State Administration of Radio coverage standards, networking standards such as the 17 standards, and the Ministry of Industry and Information Technology to accept digital TV standards, testing standards and other supporting standards 15 , has not officially come out, which to some extent, affected the development of terrestrial digital television.

He believes that digital terrestrial television to promote the key point is the signal coverage. 8 pilot during the Olympic Games coverage is not a good city, the other has begin broadcasting terrestrial digital TV programs in areas also need to replace the non-state standards into the national standard.

National terrestrial digital TV standard (DMB-TH) has been on August 1, 2007 into effect.

Hong Kong from the end of last year begin broadcasting using DMB-TH standard terrestrial digital television since the end of this year is expected to reach 640,000 users, coverage has exceeded 20%. If mainland China in the next 2-3 years to achieve 20% of TV users, will be a very, very large television market.

It is understood, CMMB network construction at the end of the year will cover 137 major cities, but the terrestrial digital TV signal coverage was difficult to complete in 37 cities. "Chip, set-top boxes and related software supporting terrestrial digital TV as early as the beginning of the national standards promulgated been listed, from the industrial chain has no technical barriers." Digital television market research firm In-stat analyst Qiang that "terrestrial digital television development of the current is limited by the speed of network construction delay. "
