Television principle

Television (TV, Video, ティーヴィー) refers to a device that uses electronic technology and equipment to transmit moving images and audio signals, that is, a television receiver, which is also an important broadcast and video communication tool.

Television uses electricity to transmit moving visual images instantly. Similar to movies, TV uses the visual residual effect of human eyes to gradually change the still image frame by frame to form a visually moving image.

The transmitter of the TV system converts every tiny part of the scene into electrical signals according to the brightness and chromaticity, and then transmits them in turn. At the receiving end, the brightness and chromaticity of each tiny part are displayed according to the corresponding geometric position to reproduce the whole original image.

The scanning system and channel bandwidth of TV signals in different countries are not exactly the same. According to international radio consultative committee's suggestion, Latin letters are used to distinguish them.
