This year, with the larger cable Chengdu digital conversion work started, the Chengdu Business Daily calls received many readers, advisory Why can not the analog TV, digital TV is Zage fees and other issues. Issues of concern to these readers, the reporter interviewed the CATV Network Co., Ltd. of Sichuan Province, Chengdu Liang Zhou Jie, general manager.
Chengdu Business Daily: Some readers have expressed, and now can see more than 40 analog TV channels, do you think is enough, why the construction of digital cable TV?
Zhou Jie Liang: digital cable is not just to increase the number of channels, so that shows higher definition,glue gun better audio, digital TV is to become a home information and entertainment terminal end to form a "triple play" of the family information platform and entertainment platform.
Cable analog TV for the people to provide the most basic program ratings. However, both men and women, both professional and preferences, through the broadcast of analog television channels are the same to see, what to see what TV stations broadcast advertising has gradually become more, people are increasingly dissatisfied.glue stick This is a popular passive viewing mode, the common people led by the television viewing audience.
With the material and cultural life of the rich people, on the demand for spiritual and cultural life gradually, no longer satisfied the public consistent with the program, but the desire for personalized viewing service, I hope from passive to active, to see what you want to see anything. People from the "watch" TV to "use" TV, TV commanding truly the master of television, it must be two-way interaction with the TV, to achieve two-way interaction, it must be the development of digital television, digital cable construction implementation. People viewing the individual needs are met, the city has improved to the degree of civilization. For this reason, the state will "city of the digital TV transition rate of 95% or more" civilized city as an important indicator of evaluation.
Chengdu Business Daily: digital cable TV, the people can bring any good?
Zhou Jie Liang: Digital TV and analog TV than the first high-definition programming, audio effects, anti-jamming ability. Television images and listen to the sound quality is very close to the studio level, less susceptible to outside interference, to avoid the string table, crosstalk, noise and other effects. Second, the number of channels multiplied. Transmission bandwidth of an analog TV channel, in principle, can be transmitted 4-8 sets of high quality digital TV programs. Chengdu original analog TV transmission of up to 40-50 sets of the basic digital TV programs now have more than 70 sets, as well as more than 50 sets of professional free choice of premium channels available to the public, more professional, you can broader selection. Third, the services greatly expanded. Digital TV can not only provide program ratings, radio listening service can also provide electronic program guides, the latest weather and other convenience services.
Chengdu Business Daily: Implementation of digital cable TV, why should we close the analog signal? Can analog and digital TV while preserving, to let some people do not want to watch digital TV to continue watching analog TV?
Zhou Jie Liang: As the analog signal is broadcast, and can not be achieved personalized on-demand needs, and analog channels occupied by the channel resource is very large, due to the current broadcasting network channels with limited resources, can only transfer 40 to 50 sets of analog channels, while the same transmission bandwidth resources are available 4-8 times the number of high quality digital TV channels.
If the two sets while retaining the analog and digital broadcast transmission system, will lead to resource constraints the network channels, resulting in great waste of resources, simply can not carry more digital channels and the transmission of high definition TV channels, a departure from the original intention of the digital broadcast television.
Therefore, the state listed on the cable industry a clear timetable to be implemented. Issued under the State Administration of Radio, "China's transition to digital cable TV schedule," above the county level city in Sichuan Province in 2010 to basically complete the transition to digital cable.
