A method for automatically converting and an apparatus for performing the same.

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. The video of an object photographed by a camera at the broadcasting station is converted into a constant video signal, and the video signal is a microphone. Along with the voice signal input through the high frequency signal is loaded on a transmission antenna. The high frequency signal transmitted through the transmitting antenna is received through a receiving antenna installed in each home and applied to the television. The high frequency signal received from the tuner of the television is mixed with a video signal and an audio signal. The high frequency signal is converted from the tuner into an intermediate frequency, and the video signal converted into the intermediate frequency is amplified from the intermediate frequency amplifier. do. The intermediate frequency amplified by the intermediate frequency amplifier is applied to the video signal detector by the video signal detector and the audio signal detector, and the audio signal is applied to the audio signal detector. The video signal detected by the video signal detector is displayed on the screen after a predetermined step. In this case, when the user selects a broadcast channel to receive through a television using a channel conversion switch, a program of a corresponding broadcasting station is displayed on the screen.

The voice signal detected by the voice detector from the intermediate frequency amplifier is amplified by the voice amplifier and output through the speaker.
