You can go to the electronic market in Nanjing, buy your own satellite antenna, and satellite receiver, **200 yuan, satellite receiver. General users will not install, you can find people who can install antennas in the electronic market, the installed ** is about 200, accept about 100 wired **, such as Henan. Hunan.
Anhui. Chekiang. Shanghai.
Star, Meiya, Phoenix TV, Guizhou, Sichuan, Yunnan, Shandong, and more than 60 other Asian TV stations, as well as foreign channels.
It's convenient not to have to pay.

Internet TV is still pretty good.

It's hard to see it without spending money.

Satellite TV, but the state seems to be in charge, and it's not easy to apply.

1. The number of channels is different.
2. Different signal requirements.
Ordinary cable TV signals are very demanding, otherwise users are prone to bad signals and snowflakes; The digital TV signal is good and the image is clear.
3. Different pre-attendant management.
Ordinary cable TV is not easy to manage, and one household pays more than one household to watch. One set-top box can be managed and only one TV can be connected.

The main difference between cable TV and radio and nuclear dumb is the way the signal is transmitted.
Cable TV is the transmission of TV signals to the TV set in the user's home through wired cables, which are usually buried in the ground or installed in buildings. This method can provide more stable signal quality and clearer pictures, but it requires the installation of a cable TV receiver in the user's home or the use of an empty device such as a set-top box to receive the signal.
Wireless TV transmits TV signals to the TV set in the user's home through radio waves, and these signals can be transmitted through satellites, terrestrial digital broadcasting or mobile networks. This method does not require any special equipment to be installed in the user's home, so it can make it more convenient for the user to ** TV programs. However, because there is a greater likelihood of interference in the signal, the signal quality of the uncalled cable TV may be affected, and the picture quality may not be as good as that of cable TV.

The differences between cable TV and wireless TV mainly focus on the mode of transmission, the effect of communication and the cost of communication
Transmission mode: Cable TV adopts closed-circuit transmission mode, with cable and optical cable as the main transmission medium, and directly transmits TV programs to users; Wireless TV adopts an open-circuit transmission mode, using wireless transmission signals, electromagnetic waves are transmitted from the air to all directions.
Transmission effect: cable TV basically overcomes the influence of external factors, the image and sound quality is high, and it can transmit multiple sets or even dozens of sets of telescript potato TV programs; Due to the use of open-circuit transmission, wireless television is bound to be affected by the interference of space radio waves, the impact of wind, rain, thunder and lightning, as well as the blocking and reflection of buildings, hills and slopes, so the quality of image and sound is poor, and the number of programs that can be transmitted is limited.
Propagation cost: Cable TV needs to build a dedicated physical network, which has high maintenance costs, and users also need to pay a certain fee for hunger chain; TVB does not need to build a physical network, the maintenance cost is low, and users only need to install antennas or set-top boxes to watch.

The differences between cable TV and wireless TV are as follows:
1.The signal transmission methods are different: cable TV transmits signals through cables, while wireless TV transmits signals through radio waves.
2.Stability and reliability: The signal of cable TV is stable, the picture is clear, and there is no interference, ** the experience is good, but the equipment and lines of cable TV need to be installed.
TVB is affected by external factors such as weather and electrical signals, and the picture is prone to interference and jitter, but there is no need for line installation.
3.Coverage area and viewing quality: Cable TV has a relatively narrow viewing coverage and is more suitable for use in cities or densely populated areas, but the signal quality is stable. Wireless TV has a wide coverage and can cover areas that are far away from the draft button, but the picture quality is not as stable as cable TV.
4.Cost: Jingbi cable TV needs to charge a certain user fee for equipment and maintenance costs, while wireless TV can be free**, and the effect is relatively good when the signal is not interfered with.
To sum up, cable TV and wireless TV have their own advantages and disadvantages, which need to be chosen according to individual needs and specific situations.

Cable TV and wireless TV are two different modes of pure visual transmission.
Cable TV refers to the way in which the signal is transmitted to the TV through a wired cable. This option requires the installation of a cable TV receiver in the house and a subscription to cable service to ** TV programs. Cable TV typically offers a more stable signal and a wider selection of channels.
TVB refers to the way in which the signal is transmitted to the TV set through the radio waves of the Muhe whispered line** TV program. This way you don't need to install any equipment, you just need to have the corresponding app on your TV or mobile phone to watch the TV show. Over-the-air TV typically offers more freedom and flexibility, but the signal quality may not be as stable as cable TV.

1. Platform differences:In general, network TV.
The machine adopts a relatively intelligent platform system (such as Android.
TV, Apple TV
etc.), users can achieve more intelligent operations on the TV; Ordinary TVs use systems independently developed by TV brands,Relatively few functions、The degree of intelligence is slightly lower,The experience is not as good as that of network TVs。
2. Content differences: network TV accesses content through wired or wireless networks, and provides diversified audio-visual content including **, audio, etc. (the content coverage is relatively comprehensive); Ordinary TV sets are connected to TV stations or IPTV signal sources, and can only ** live cable TV content (network TV sets cannot provide this service).
3. Difference in cost: The network TV only needs to be connected to the broadband signal to watch, without additional payment; Ordinary TVs need to pay a certain amount of TV viewing fees on a quarterly or annual basis, which is equivalent to paying an additional fee for broadband at the same time.
Cable TV has certain advantages in clarity and stability, but there are fewer programs and the cost is more expensive, resulting in many people no longer installing cable TV, but cable TV is still used a lot in the elderly group, and most of the young people now install network TV.
What is the difference between digital terrestrial TV and cable TV? At present, what we generally call TV mainly refers to three types: terrestrial (wireless) TV, cable TV, and satellite (wireless) TV. >>>More

Upstairs is right, just buy a TV card, I use a TV card to watch TV now on the computer, Tianmin's brand, very famous. Just plug the TV card into the PCI slot on the motherboard, install the driver, and then install the application (which is included in the CD with the card). Then there is a wired socket on the back of the TV card (the same as the wired port behind the TV),After connecting,Turn on,You can set it up in the TV card app and**Cable TV。
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. >>>More
