Question 2: What are the advantages of digital TV? Digitalization is the development trend of the world. After the digitalization of cable TV, it will be able to provide users with richer services. Compared with analog TV, digital TV has obvious advantages: ① high-quality audio-visual effect: the signal quality of the program is obviously improved, the picture is clearer and the sound quality is more beautiful. ② Rich content and free choice: Digital TV provides a large number of video-on-demand and interactive programs, and users can choose to watch personalized content.

Question 3: What is the use of mainland radio and television to promote digital TV? Under the slogan touted by XX leaders, the analog will be quickly converted into digital TV. On the surface, it is to improve the picture quality and facilitate management. In fact, it is to monopolize, and it is forbidden for multiple TVs to share a signal source, which is convenient for radio and television to get money from it. Do you think that a garbage monopoly like Tianchaoguang Electric Power Company will serve the people just to raise a group of idle people?

A low-tech redundant device like a set-top box can make you pay if it is monopolized by the mainland. .

Hong Kong doesn't have to pay radio and television viewing fees at all, and people don't have to buy any junk set-top boxes at all. Television sets in Hong Kong are equipped with wireless digital terrestrial wave receivers, so you can watch high-quality programs by connecting antennas. What kind of bird is the mainland? High definition is not popular yet, and the standard definition is still 4: 3, so the flat panel will be deformed, and you have to buy high-priced junk program packages of radio and television. .

At present, only Hong Kong and Japan really use high-definition terrestrial digital TV broadcasting. Because of the monopoly of radio and television, the mainland can only use its own digital set-top box, and the price is determined by radio and television. Most wireless terrestrial waves are only used to insert junk shanzhai advertisements, which increases the income of radio and television.

Television stations in Hong Kong have more advanced relay equipment and higher signal rate, so the picture quality is clearer. .

Question 4: What are the advantages of installing digital TV? Compared with analog TV, digital TV has the following advantages:

1. The picture clarity of programs received by digital TV is equivalent to that of DVD, and the picture quality is obviously improved;

2. Users with digital TV set-top boxes can watch hundreds of TV programs, including basic programs (such as CCTV- 1, Hunan Satellite TV, etc. ) and paid digital programs (such as career guide channel, happy pet channel, first theater channel, etc. );

3. In the past, when watching wonderful programs, advertisements were often inserted, but the State Administration of Radio, Film and Television stipulated that it was strictly forbidden for paid digital channels to insert advertisements when broadcasting programs;

4. Digital TV set-top boxes often have various interactive functions (such as video on demand, TV payment, instant messaging, news, program recording, interactive games, etc.). );

5. Conditional areas can also replace or upgrade the set-top box according to the situation, thus achieving the purpose of watching high-definition interactive programs (such as CCTV- HD, CHC- HD movies, SiTV- new vision, etc.). ).

Question 5: What's the use of cable TV? What's the difference between cable TV and antenna? The function of CATV is to transmit the signal of CATV. It is connected with cable TV. Compared with ordinary antenna, it is thicker, but it is coaxial cable. The antenna only transmits wireless signals. I really look forward to helping you adopt it.

Question 6: What is the function of the network digital TV set-top box? (1) Electronic Program Guide (EPG): It provides users with an easy-to-use and humanized way to quickly access the programs they want to watch, and through this function, users can watch TV programs that will be broadcast on one or more channels or even all channels. (2) High-speed data broadcasting: it can provide users with various information such as stock market information, ticketing information, electronic newspaper, popular websites and so on. (3) Software online upgrade: it can be regarded as one of the applications of data broadcasting. The digital DVB broadcast server broadcasts the upgraded software according to the DVB data broadcast standard, and the set-top box can identify the version number of the software, receive the software when the version is different, and update the software stored in the memory. (4) surfing the Internet and sending and receiving e-mails: The digital set-top box can conveniently realize the function of surfing the Internet through the built-in cable modem. Users can surf the Internet and send emails through the built-in browser of the set-top box. At the same time, the set-top box can also provide various interfaces to connect with PC and use PC to surf the Internet. (5) Support interactive applications, such as video on demand and interactive games. (6) Conditional access: The core of conditional access is scrambling and encryption, and the digital set-top box should have descrambling and decryption functions.

Question 7: Can I have two cable digital TVs at home? No, you can watch the same program through the connection. Insert a remote control cable to connect to your room. The remote control cable 5 yuan 1 can be remotely controlled in your room. You cannot remotely control two remote controllers at the same time.

Question 8: Can a cable TV family only use one TV? Analog cable TV and digital cable TV, the analog cable TV company has only one line to the home, paying the monthly rent for one TV, installing an extra TV on the auxiliary machine, and paying the monthly rent 1/2. However, in the process of decoration, you can use a cable box or a cable distributor with one in and one out, so that every room can be used. But cable TV companies are not allowed to know that there are many people who answer this way, but they also turn a blind eye. I won't spend any more money. Digital Cable TV Cable TV uses a set-top box, and there is only one line to the home. If you pay the monthly rent for a TV, you have to install an extra TV on the auxiliary machine, and you have to pay the monthly rent of 1/2. Two TVs can be tuned separately. If you only apply for a host, because the channel is tuned in the set-top box, you can only make a set of TV programs, that is, you can only watch the same set of programs in several rooms using the three-way or cable splitter. No matter what your area is, you should reserve a cable TV interface in every room. It doesn't matter if you don't use it for the time being, in case you need it later.
