The characteristics of the television set are: the method of using electricity to transmit the visual image of the activity in real time; Similar to movies, TV uses the visual residual effect of the human eye to show a still image with gradual changes frame by frame, forming a visual living image; The transmitter of the TV system divides the various subtle parts of the scene according to brightness and chromaticity.

After being converted into an electrical signal, it is transmitted sequentially; At the receiving end, the luminance and chromaticity of each fine part are displayed according to the corresponding geometric position to reproduce the entire original image.

Television sets can generally be used as a medium for the dissemination of information, and the specific uses include the following:

Principles of television. Television uses electricity to transmit visual images of the event in real time. Similar to movies, TV uses the visual residual effect of the human eye to show a still image with gradual changes frame by frame, forming a visual living image;

The transmitter of the TV system selects the various fine parts of the scene according to brightness and chromaticity.

After being converted into an electrical signal, it is transmitted sequentially;

At the receiving end, the luminance and chromaticity of each fine part are displayed according to the corresponding geometric position to reproduce the entire original image. The scanning system of television signals in various countries is not exactly the same as that of channel broadband, and the Latin alphabet is used according to the recommendation of the International Radio Advisory Committee (CCIR).

From the Internet.

Although there are many functions of TVs nowadays, such as playing games and sending emails, I think the networking function of TVs is more useful.

We know that today's TVs have a wide range of functions, and they are no longer just a single TV program.

Not only computers, mobile phones, and tablets can be connected to Wi-Fi, but now TVs can also be connected to Wi-Fi. I think the internet connection function of the TV is more useful. Because sometimes watching TV, it is very helpless to find your favorite program or TV set in more than 100 channels, and TV programs are often interspersed with a lot of advertisements.

At this time, we can connect to the Internet through TV and look for TV dramas or variety shows we want to watch on the Internet, so that we can avoid the disadvantages of TV program advertisements and save our time. If it is a TV series, there is a certain time requirement, but by searching on the Internet, you can search for the TV series we like without time limit.
