APPARATUS AND METHOD FOR CONTROLLING AUIDO OUT IN TV AND RADIO BROADCASTING SERVICE RECEIVER

摘要

An apparatus and a method for controlling an audio output in a TV and radio broadcast receiver are provided to prevent unnecessary power consumption and noise generation automatically in receiving stereo or mono audio through a TV broadcast service or a radio broadcast service. A microcomputer discriminates a type of a selected broadcast service(S11). If the service type is a radio broadcast service, the microcomputer selectively enables the first to fourth speakers installed at a stand(S12). The microcomputer controls an operation of an audio processor to output stereo or mono audio received through the radio broadcast service via the enabled first to fourth speakers. The microcomputer checks a type of audio received through a TV broadcast service. If the audio type is a general stereo or mono audio, the microcomputer selectively enables the first and second speakers installed at a display head(S14). The microcomputer controls an operation of the audio processor to output stereo or mono audio received through the TV broadcast service via the first and second speakers of the display head(S15). If the type of audio is audio of a 5.1 channel, the microcomputer enables all the first and second speakers of the display head and the first to fourth speakers of the stand(S16). The microcomputer controls the operation of the audio processor to output the audio of 5.1 channel received through the TV broadcast service via the first and second speakers of the display head and the first to fourth speakers of the stand(S17).
