For example, if a hotel has 100 TV sets, it must be equipped with 100 set-top boxes. Each set-top box is charged according to the monthly 25 yuan, and the annual subscription fee is 300 yuan, so 100 set-top boxes will cost 30,000 yuan, and the five-year cumulative subscription fee is150,000 yuan, and any unit is150,000 yuan. In addition, the set-top box has a remote control, and the TV has a remote control, so it is not convenient to use the two remote controls together. This product can solve this kind of problem. Apply for 12-24 set-top box in the radio and television bureau, use 1-2 sharer, and add 12-24 digital station on the basis of the original reserved program, which can save a lot of set-top box investment and monthly rent.

Fourth, the principle analysis of digital TV set-top box * * *

Before explaining the * * * enjoyment principle of ATV 12 digital TV * * enjoyment device, let's first understand how TV receives digital TV programs. Everyone knows that digital set-top boxes must be installed to watch digital TV programs now. In fact, the function of this set-top box is to receive the digital signals (image and sound signals) of radio and television stations, and then the set-top box decrypts these digital signals and converts them into analog signals, and then transmits them to TV. From here, you should know that what is actually played on TV now is an analog signal, not a digital signal. The real digital signal is from the radio and TV station to your set-top box, and the set-top box to TV is the converted analog signal.

Current digital TV signal transmission process:

Radio and Television Station-> Set-top Box [Digital Signal]

Set-top box-> TV [analog signal]

Through the above understanding of digital TV signal transmission process, let's take a look at the real * * * enjoyment principle of ATV 12 digital TV player. The core technology is to make your own signal sources with different contents, that is to say, collect your own signal sources, and then mix the collected signal sources with different contents and transmit them to each TV set through the TV network, so that each TV set can watch TV programs with different contents.

Specific * * * enjoy principle is:

Step 1: Make your own input signal sources with different contents.

Because ATV is a digital TV player with 12 channel and needs 12 signal source inputs, what should be used as the signal source input? There are several options:

1. Use the 12 set-top box as the input signal source.

2. Use 12 DVD player as input signal source (DVD output is used as movie channel).

3. Use the TV channel player operated by 12 hotel as the input signal source.

4. Use 12 satellite antenna as the input signal source.

5. Cross-use the product of the above four schemes as the input signal source.

(For example: 5 set-top boxes +3 DVD players +2 TV channel players operated by hotels +2 satellite antennas = 12 inputs).

Step 2: Output signal sources with different contents.

Output your own 12 signal source with different contents to the main external line of all your TVs (before the power amplifier), and all TVs can watch this 12 channel.

Through the above two steps, all TV sets can enjoy TV program content.

Why do you want to output to the main outside line?

Because in the past, all signals that can be watched on TV were transmitted from radio and television stations to every TV set through the main external line, now we don't need radio and television stations to give signals, and the signals we use are the signals output by the digital TV * * enjoyment device (12 signal source), so that the signals of the digital TV * * enjoyment device can be transmitted to every TV set through the main external line, and all TV sets can watch these 12 TV sets. In fact, through this technology, you can even make fifty or sixty signal sources (equivalent to fifty or sixty channels) and output them to each TV set, so that each TV set can watch TV programs of different channels independently.
