The last post Some netizens reflected that they were long and stinky. This lesson learned lessons, used less terminology, used more pictures, and met the requirements of science popularization as far as possible. All the information comes from the Internet and anecdotes. The author is not engaged in the cable TV industry. There are a lot of banter words in the text, and those who don't like to lightly spray are purely happy during the Lunar New Year.
Even if people do not watch TV at ordinary times, the Spring Festival Gala usually has to accompany the old people to watch it for a while. This has been positioned as a national project! Not to mention how users say, do not look at the Spring Festival Evening, how to understand Tucao ah? CCTV is not short of money. It is absolutely fine to use the best equipment and the picture quality is good. I heard that there is a 1080P 50M bit rate. But how does the effect of my LCD TV look better than the old CRT TV? In the following, we borrowed the pictures from the Feng Shao's works in 1942 to explain that the localization of the character language was only to enhance the dramatic effect and did not mean any discrimination in the region. (Firstly, TV stations and radio and television networks are two different things. We all know this.) 
Leadership Lao Zhao: This high-definition signal of the Spring Festival Gala 1080P full HD, how did I accompany the leaders to the grassroots inspection last time, people's home TV clarity so bad?å’± å¼€ å¼€ å¼€ å¼€ å¼€ å¼€ å¼€ å¼€ å¼€ å¼€ å¼€ ç ”ç©¶ ç ”ç©¶ ç ”ç©¶ ç ”ç©¶ ç ”ç©¶ ç ”ç©¶ ç ”ç©¶ ç ”ç©¶ ç ”ç©¶ ç ”ç©¶ ç ”ç©¶ ç ”ç©¶ ç ”ç©¶ ç ”ç©¶ ç ”ç©¶ ç ”ç©¶ ç ”ç©¶
The technical department old money: The equipment is changed, what year's equipment? There is the standard cable set-top box at the user's home, and the cost for a block of 200 or more can be better? Have to change. 
The financial department old grandson: For what change, one month cable TV is enough to buy a lunch, equipment maintenance is enough to send wages, where there is money for ah? Also, ah, there were a lot of people who sold the cable to the consumers last month. You said that the young people nowadays are not watching the news broadcasting the excellent situation in the motherland. They have to look at the American TV series. TV shows are not enough? 
Xiao Li, Network Department: For the series of shredded devils? Even I can't stand it. There's no internet now? Speaking of the Internet is my own bank, and the bandwidth of the Cable Communication Company has to be mentioned. Telecom Unicom is engaged in 100Mbps access. Complaining about the increasing speed of the cable connection, we can't go on without speeding up. I can compare this. Cable TV makes money! 
Office Lao Zhou: I would like to add two sentences. Ah, local TV programs must also guarantee transmission quality. Local requirements must be handled well. In addition, six sets of analog signals have to be broadcasted, so that poor families in the city may have to watch television. This is a hard policy of the central government. 
The summary of leadership Zhao angry: You talk about you, the analog signal era is too bad signal, and now the signal is good and quarrel back and forth grabbing resources, this Spring Festival Evening digital signal high-definition useless to me, simply return to the analog signal forget! 
The secretary joined the leader Lao Zhaobian and said: XX TV's Lao Zheng asked you to have lunch at noon, I heard that you have reserved frequencies, and you want to put their programs back in. You see this thing.... ..... 
Leader Zhao thinks for a moment and yells to the technical department's old money: old money, ah, there is still a reserved frequency of idleness. In the afternoon, I come to my office for a break!
Ok, here's enough to get it right. On the coaxial cable of this cable TV, you're running a cabled cable at the same time, analog signal (national policy regulations), digital SD signal (for SD set-top box), digital HD signal (for HD set-top box ), have to reserve some business margin. Whoever has a balance of interests must be considered. Before the Spring Festival Evening Gala, there are many celebrities who say, "What is the Spring Festival Evening?" This cable TV has to be taken care of. 
From the perspective of charges, the existing cable television operates on a cycle of low-cost, low-quality services. It can be compared with the Indian railway system. The number of kilometers of turnover in terms of the number of people per year is larger than that of China. What is the ride experience? Now. However, watching the Spring Festival Gala also found that online video can not be comparable to the place where the cable, which is the server can not carry hundreds of millions of clients at the same time high-definition video access, only to SD a few minutes later, read two or connect the cable set-top box In the end, we still have to rely on the cable set-top box to finish watching the Spring Festival Gala.
Below to give a picture to talk about the source of a variety of program clarity (here to temporarily consider the difference between the code rate and compression format), simple painting, will see. 
The domestic market is a “high-dynamic range†market. Flat-panel TVs in the first-tier cities have entered the second round of replacement. Many users have been familiar with the picture quality, HDMI connection, and IPTV. The cable TV network is also mature. The places below the third-tier cities have just begun to touch the tablet, cable TV / network providers are also scolded, the basic is to be able to play on the line, fool users, there are actually IPTV only provides CVBS connection wonderful work.
The network content is uneven, so the span is relatively large. This is easy to understand. Need to remind everyone to pay attention is not to let the connection method to downgrade your picture quality, the most common CVBS composite video signal interface, for example, this interface is regarded as a veteran who went to the countryside to go north and south, when I used it to play red and white machines to play FC The game has never doubted its image quality and it can be used when connected. There is almost no compatibility issue. But in that era, the computer monitor was only 640,480 resolution. At that time, the Hong Kong sisters now estimated that they had grandchildren. The times are not the same, and now you can use it without using this interface. Check your SDTV cable box. If you still use this interface, it means that the signal you see is best on the 280 line. As for what Hu Cheng is, the picture quality is not good.
The picture on the left is a picture of the CVBS composite video signal cable that the domestic box (millet LeTV plus Lynx Box) still keeps the interface and provides. See the figure below, because the volume is limited to 3.5mm interface, but the other one of the joints exposed its essence, are very understanding of national conditions ah. 
Some of the posts on TV discussions have users X ask: I've seen the LG's LA6600, smzdm recommended many times, we give the review price?
A: Yes, very satisfied. (X thought, buy it)
B answered very clearly and spent half a year, which is excellent value for money. (X thought, well, it's it)
C: The picture quality is very poor and Hu Cheng is a piece. Can I be the case? (X is messy, saying that this LG TV product is too indecisive to buy it or not?)
These TV users' evaluations of TV may not be based on the same definition video source, so it is difficult to use TV as a basis. Moreover, "Hu Chengcheng" is an inevitable problem that analog signals are connected to large flat-screen televisions with CVBS lines.
Speaking for a long time, it seems that there is no recommended TV model. Let's just say, now TV manufacturers are not easy. In the mature Red Sea TV technology, the head of the Red Sea kills blood. The picture quality is enough for most users . Enthusiasts please move to ten. Eight experience posts
Anything, you see people write a high-definition player in the mall tried more than a dozen models TV did not pick satisfaction, that the picture quality is unsatisfactory. People's enthusiasts that player is "to kill you 3000", oh wrong, is the popcorn A300 ( Cloud media ), is the Sigma chip supports 1080P24 frame output, plus NAS and other people's HD warehouse costs, can basically buy Taichung-side TV, you don't have to catch up with the cat's box of pseudo-1080P output that you get for 1 cent.
Besides, when you buy a TV, you still complain. Do you want people to feel like TV? Now a pound of TV is not much more expensive than a pound of beef and mutton. Making such a high-tech TV can only change two sheep. You can only change for a cow, and life is so difficult! The heroes of the people are so stunned. Don't believe, please look at the following questions and answer them: 1) Yang used to live alone for 16 years. How did he cut his nails? 2) Xiao Zhao was locked in his ankle for many years. How did she change her underwear? 3) Mei Chaofeng practiced Jiuyin white bone claws, nails are so long, how to wipe the buttocks on the toilet?
