In general, a television receives a broadcast signal transmitted from each broadcasting station through an antenna so that a broadcast corresponding to a screen is displayed. An image of an object photographed by a camera at the broadcasting station is converted into an image signal, and the image signal is a constant high frequency signal. It transmits through a transmit antenna. The high frequency transmitted through the transmitting antenna is received through a receiving antenna installed in each home and applied to the television. The high frequency received by the television is separated from the image signal, and after a certain step, the image signal is displayed on the screen. In this case, when the user selects a broadcast channel to receive through a television by using a channel conversion switch, an image signal of a program of a corresponding broadcasting station is applied to the receiving tube (CRT) and displayed on the screen.

In the case of the receiving tube of the television, the image signal received through the receiving antenna is the electron beam scanned from the electron gun installed in the rear of the receiving tube is deflected from side to side by a left and right deflection coil for deflecting the electron beam in the left and right directions, The image is displayed on the screen by being deflected in the up and down direction by the up-down deflection coil which deflects the electron beam in the direction and touching the phosphor of the screen.

The channel switching method of the current TV is a rotary type that allows the user to switch channels manually and a remote controller (remote cotroler) to scan the infrared rays corresponding to the selected channel to the receiver built into the TV. There was a way to switch between them, but this method always remembers the broadcasting time and channel to be watched by the user, and it is very important to remember the time when busy or watching other channel broadcasting. It is difficult to watch a desired broadcast or there is an inconvenience of watching after a certain time elapses.
