HC TV Network China HD TV development has lagged behind. In the cable digital, CMMB commercial, live satellite broadcasting, and many other hot spots in front of God, the promotion of high-definition television seems very shy. HDTV is the next great development of China’s broadcasting an inevitable, despite the environmental and system operating status of all constraints, but the General Administration of the layout of the high-definition television could not stop. Forecast and from abroad, high-definition can also be driven by the trend of the audiovisual industry. It is reported that in the next five years, the European high-definition home to more than 170 million, while North America’s high-definition television penetration will rise to 34%.
Beijing Olympic Games to Chinese audiences the opportunity to experience the high definition brings regret moving. 2008 can be the cause of the rapid development of China’s high-definition year, especially in the January 1, 2008, the Central TV station Comprehensive Channel HD officially launched at the same time, Beijing had its launch terrestrial digital television, which marked China’s terrestrial wireless Radio and TV Digital officially launched.

A combination of policy support industry started Seen in a recent report from the General Administration of China in recent years, high-definition highlights the industry will focus on the terrestrial digital TV. Special radio and television industry from the development of China’s environmental point of view, it is necessary to ensure that the entire cable digital TV switch a smooth transition, but also the implementation of Satellite TV The “villages” project, so the wireless signal coverage highlights industry must be done to promote support. Currently Cable television For the mode of transmission of high definition channels are pay programs, if the combination of HD and wireless vigorously promoted in recent years, let alone a breakthrough in technology and standards, and the terrestrial digital television will break through.
Terrestrial digital TV this year, caught a good opportunity. The state has invested 2.5 billion, plans to use three to five years building a nationwide digital terrestrial television system, which promote national cable, terrestrial, satellite and complementary digital broadcast television network construction is great.

Business operations is the key to the high enthusiasm
First be sure, with high definition technology, compression and transmission technology, high-definition signal transmission and storage costs are significantly reduced. However, in our country, whether operators or equipment suppliers to promote the enthusiasm did not seem high. To high-definition set-top boxes, for example, currently produces high-definition set-top box manufacturers of major markets abroad, while the domestic market is only the initial start. For operators, the public nature of the terrestrial digital television is clearly not conducive to enterprise operation, reasonable profit without the support of tower construction and transformation of the complement of relay stations built the program to buy and braided hair products such as set-top boxes and feeders procurement, promotion and maintenance of recruitment and other sources of funds is the biggest problem.
