Abstract

According to the present invention, when watching TV at night, the volume of the television needs to be reduced, and the problem of not being able to effectively watch the television broadcast generated and to listen to the radio broadcast, for example, to operate a separate radio or audio system separately. In order to solve the inconvenience, it is an object of the present invention to provide a broadcast listening device using a remote control that can listen to the television broadcast and radio broadcast through the remote control of the television. Accordingly, the present invention provides a remote control mode for a television remote control having a remote control transmitter which transmits a remote control data signal when a user selects a channel of a television broadcast and inputs a key. A mode selection unit for setting the TV broadcasting and the AM and FM radio listening mode, and keying in the channel of the selected predetermined television broadcasting and the AM or FM radio receiving frequency, and adjusting the listening volume of the broadcasting by key input. A microcomputer for generating a control signal based on a mode state set in a key input unit, the mode selection unit, and a result of recognizing a predetermined broadcast channel or broadcast frequency and control volume inputted in the key input unit, and a synchronization control signal of the microcomputer. By inputting a television broadcast signal or AM or FM radio reception frequency Tuner to tune to and receive an intermediate frequency signal through an antenna, a voice detector for detecting a voice signal of an intermediate frequency signal amplified by an intermediate frequency amplifier, and a control volume of the microcomputer A volume control unit for adjusting the volume of the voice signal detected by the voice detector by control, a speaker for outputting the voice signal whose volume is controlled and amplified by the amplifier, and a television broadcast or AM through a headphone. Or a headphone terminal into which a headphone plug can be inserted to listen to an FM radio broadcast, and a channel number or a frequency number according to the tuning of the television broadcast signal or the AM or FM radio frequency signal to the tuner under the control of the microcomputer. Characterized in that it comprises a display unit for displaying.
