Three highlights of zhongxing-9 satellite receiver;

One: the transmission program is not encrypted.

As an efficient, long-lived and highly reliable live broadcast satellite, the transmission program of Zhongxing-9 is not encrypted, and residents can watch digital programs only by installing satellite ground receiving facilities. "Zhongxing 9" transmitted 47 sets of standard definition digital TV programs, and TV viewers watched them for free.

Two: the signal can go straight to home.

"Zhongxing 9" is a direct broadcast satellite, and the signal can be directly transmitted to the home without the need for TV broadcast. You only need to install a 45-60cm "small pot" on the ground to receive it.

Three: large coverage area

Compared with terrestrial and cable digital TV, the advantage of satellite live digital TV lies in its large coverage area. At present, the price of a satellite TV receiving station is only a few hundred yuan. Specifically, after the satellite was put into use, it not only greatly increased the transmission capacity and improved the quality of program viewing, but also improved the coverage rate of radio and television in China to over 98%.

On the difference between zhongxing 9 and other domestic satellites

1. Other domestic satellites generally adopt DVB-S mode, while China's self-developed video coding standard ABS-S mode is adopted by Zhongxing No.9, whose purpose is not only to provide environmental support for local technical standards, but also to consider national security. It is expected that people will not watch non-domestic satellite TV programs. According to 129 and its corresponding regulations, generally speaking, people declare that only one satellite can be fixed when receiving satellite TV. However, in the past, most satellite signals adopted a unified international standard, and it was difficult to control whether users only watched a certain satellite signal specified in the license plate. After the adoption of ABS-S in Zhongxing-9, the special receiver can't watch other satellite signals.

2. The difference between ABS-S and dvb-s, both of which are video coding methods, is essentially the same. They are two different ways to achieve the same goal. DVB-S is an international standard for satellite broadcasting, which is adopted by most synchronous satellites over the equator. DVB-S technology is very mature, and the chip price is extremely low, so there are many receivers with tens of dollars on the market now. ABS-S is a standard formulated by China according to its own needs. Zhongxing 9 can only be industrialized after its launch, and its market is limited to China. At the beginning, the price of ABS-S machine was around 300-400 yuan, among which an ABS-S decoding chip was loose. Now the price may be above 100, but once the industrial chain is formed, it is estimated that the price will soon drop to tens of yuan in two or three years.

3. The difference between Zhongxing 9 and CIGNA 1. In the past, Sinopec satellite 1 10.5 domestic live broadcast platform was encrypted, and the satellite power was not large enough. In many places, a 75 cm jar is needed to receive it. In fact, it is not suitable for personal reception, nor is it a live star in the full sense. In fact, it can only be broadcast to rural areas by other means after collective reception. In addition, the satellite was illegally interfered by XX power many times later. Now, Zhongxing 9 is different. In most parts of the country, you only need a small pot of 45CM to get it for free. The technology is more advanced and will not be illegally interfered.

4. The difference between Zhongxing 9 and Zhongxing 6B/ CIGNA 3. The former uses KU band, which is a real live satellite for ordinary residents to receive satellite TV programs directly. The latter is not for this purpose. Zhongxing 6B/ CINO-3 adopts DVB-S standard and C-band transmission (cauldron), which is mainly used to provide program sources for local cable TV networks. Although some farmers have installed it in rural areas at present, it is not suitable for personal reception because of the need to use the large antenna of1.5m. ..

5. There is a big difference in frequency between C-band and ku-band Ku-band, which has rain attenuation effect. The heavier the rain, the more the signal is affected. The intuitive performance is that there may be mosaics, and what is more serious is that there is no signal at all. Generally speaking, receiving only needs a small-sized offset feed antenna, even as small as 35 cm. C-band frequency is low, which is less affected by rain attenuation. As long as the pot is slightly larger, the stability of signal transmission can be guaranteed. Generally, a 1.5m feed antenna is used. Therefore, all the program sources of cable TV networks come from C-band satellites, and KU-band satellites are rarely used. Therefore, even if Zhongxing 9 goes to heaven, the program on 6B/ Xin3 will not disappear. Now the farmers' uncles who secretly watch ZTE 6B/ CIGNA 3 programs in the cauldron can watch them normally without any influence. Only with Zhongxing 9, they can go into battle lightly, and they can legally watch more TV programs by applying for receiving licenses.

6. DecreeNo. 129 of the State Council. After the launch of Zhongxing-9, in the initial stage, the instruction 129 was not loosened. On the contrary, with the launch of direct broadcast satellites, the crackdown on illegal satellite TV reception has increased. But gradually it will definitely change. According to the design capacity of Zhongxing 9, it is not only used to transmit 47 sets of SD programs. Moreover, Zhongxing-9 is a direct broadcast satellite, which is only used for village-to-village communication projects, which is very wasteful. Personally, I guess there will definitely be some high-definition programs and some paid programs in the future, and then gradually allow urban residents to apply for installing receiving equipment to receive such programs.
