Is it possible to combine computer signals into cable TV signals?

Use a VGA signal converter to convert the signal output by the computer into a ** signal, and send the ** signal and the audio signal output by the sound card to a cable TV modulator, and then the RF signal output by the modulator is mixed into the cable TV network through a mixer (can be replaced by an ordinary distributor), that is, it can be transmitted in the cable TV network.

It is recommended to purchase a sagile frequency converter for the modulator, so that the RF frequency can be easily adjusted.

The RF signal output by the agile frequency can be transmitted over a distance of about 200 meters via the SYV-5 cable, and if the distance is too long, a cable TV amplifier can be used.

Under normal circumstances, you can use the ** input function of TV to play back this group of audio and video signals,If you need to transmit cable TV, of course, you need the corresponding transmitting equipment,It doesn't matter if you use the signal amplifier and output end when you enter the cable TV network。

To output to the display** and audio cable TV signal, you need to insert a TV card (PCI slot) on the computer motherboard, such as Meiruhua, Tianmin, Yameisen, etc., (plug in the cable head) can be convenient to watch dozens of local cable TV signals. (with **output).

It can also be external.

**All in the tens of yuan - 200 yuan).

If the distance is too far, you can add a signal amplifier.

There are two ways to watch cable TV on your computer:

First, use a TV card. A TV card is an expansion board that is plugged into the motherboard. The cable TV line is connected to the TV card, and the corresponding software is installed on the TV, and the TV program can be passed through the software. This option is relatively inexpensive, but requires a host computer to work with.

Second, use a TV box. The TV box is an independent electrical appliance, the cable TV line is connected to the TV box, and the TV box will convert the TV signal into a VGA signal output to the display, and you can watch TV. The cost of this solution is relatively high, but only one monitor is required, and no computer is required.

Cable TV converts computer monitors, why doesn't it work if you buy a converter.

No, a computer is a computer, a TV is a TV, and you can't combine the two into one.

Computers and TVs are generally connected via VGA cables and HDMI cables. Since the connection method is different, the way of outputting audio will also be different.

1. If the computer and the TV are connected through the HDMI cable, the HDMI cable can transmit the audio signal at the same time, so you only need to set the TV as the default speaker in the sound setting interface of the computer to output the audio of the computer to the TV.

2. If the computer and the TV are connected through the HDMI cable, the VGA cable can only transmit the best signal, not the audio signal, so you need to buy an audio cable that turns the lotus head, one end is inserted into the computer's audio output jack, and the other end is plugged into the audio input interface of the TV, pay attention to distinguish the left and right channels.

There are also some other audio ** equipment ** signal is different, it is an analog signal to digital signal, etc., it is necessary to have a ** signal converter to achieve conversion, I use the same three-dimensional converter effect performance is quite stable.

。。。Belch. Looking at your question, I guess you want to use a TV as a computer monitor?

Today's LCD TVs generally have a computer interface. There was VGA earlier. All of them now have HDMI.

If your TV doesn't have these two interfaces, then the note is very old.。。 Then even if you want to convert the VGA to a wired interface, it won't work. Because the resolution of earlier TVs is low, it is generally 640*480.

None of today's graphics cards support this resolution.

There should be a wireless LAN and two computers, one computer that can send information to the other. One of the computers acts as a **server, receives digital TV trouser shouting programs from cable networks, and then sends them to the other computer. There are roughly two technical routes.

The first is to configure the server with a receiving device with DVB-C demodulation function, receive and demodulate the signal from the cable TV coaxial cable, and the server will send it into an IP package and send it to another computer through the local area network. After Hu Kuye opened the IP package on another computer, it was broadcast after demultiplexing, decoding, and audio synchronization.

Second, with the help of cable TV set-top box, through the composite *** resistance interface or component ** interface or HDMI interface, the ** server receives the analog tone signal after decoding. Then do a full set of audio coding work: AD conversion, compression, audio compression, production stream information flow, into an IP package, and then send it to another computer through the LAN.

In short, it's cumbersome, and only professional equipment is available.

I don't think so, it's not easy.
