How to connect a TV set-top box to a set-top box

Generally, the TV box is first connected to the old CRT TV, so that the TV can receive the digital TV signal from the set-top box, and then connected to the set-top box to play digital TV programs. Since most TV sets now have AV interfaces, TV boxes are useless in practical use and can be completely discarded. It is suggested that the TV can be directly connected to the set-top box to watch digital TV programs. The method is:

1, required: one TV, one set-top box and one AV composite video cable;

2. Connect one end of the white cable to the cable junction box and the other end to the signal input port behind the set-top box. Then insert one end of the AV composite video line into the AV output port of the set-top box, and pay attention to the one-to-one correspondence between the color of the line and the color of the interface;

3. Insert one end of the AV composite video line into the AV input port of the TV, and pay attention to the one-to-one correspondence between the line color and the interface color;

4. After the set-top box and the TV are successfully connected, start the set-top box and the TV;

5. Switch the TV channel to AV (video) channel with the TV remote controller, and the TV will display the startup screen of the set-top box, indicating that the set-top box has been perfectly connected with the TV.

How is the set-top box of Seven Days Hotel made? Do you need to pay any fees? I can order movies and TV. My small hotel has a room 10, and I want it, too.

This kind of set-top box usually needs to find a local cable TV company, such as Gehua in Beijing, and then the cable TV company needs to wire all your areas. After laying the wires, the company will send you a set-top box, some of which will be paid and some will be free. Then you get a bank card, and the cable company will deduct the viewing fee from your card every month. Set-top boxes generally have on-demand functions. If you are a hotel and need an interface to connect multiple set-top boxes, you must buy it from a cable company. In short, you can search online, or ask if there is a set-top box in your area and which company opened it, and then you can call this company to ask. I hope I can help you.

How can I watch cable TV without a set-top box in the hotel?

There are generally two ways.

First, digital-to-analog conversion. The digital audio and video output by the set-top box is converted into radio frequency signals by radio frequency, and then mixed and sent to each room. The room TV directly receives analog signals without additional equipment. The current coaxial cable can be reused on the line. Low cost. However, due to the conversion to analog signals, the line noise will be more obvious, resulting in the terminal effect is not as good as the direct set-top box, which is prone to snowflake noise. This method generally requires a set-top box for each channel, and it is meaningless if the channel to be transferred exceeds or is close to the number of rooms.

Second, the digital signal is converted into a network signal for transmission. This is suitable for free channels. The signals are packaged and sent to the local area network through special equipment, and are received and decoded by the network set-top boxes in each room. Few front-end devices are needed, and only one device is needed for each frequency point. If customized, a device can correspond to up to four frequency points. However, every room needs a set-top box, and the total cost is not low.

Either way, you must get permission from the local radio and television department, otherwise it is illegal.
