Television refers to the equipment that uses electronic technology to transmit moving images and audio signals. It was first invented by British engineer John Logie Baird in 1925. Television is recognized as "one of the most important inventions of the 20th century". Television is mainly composed of signal system, scanning system and power supply circuit. Modern TV can be divided into five categories: network TV, digital TV, Internet TV, mobile TV and outdoor TV.

Standard TV refers to the use of electronic technology and equipment to transmit moving images and audio signals, that is, TV receivers, which are also important broadcast and video communication tools. 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.
