Abstract

본 발명은 음성다중방식의 JV오디어 데이타의 디지탈 전송에 있어서 에러 감지를 위한 별도의 패러티비트의 삽입 없이 수신한 'TV오디어 전송모드'정보에서 에러를 감지함으로써 에러 발생시 오디오 데이타를 묵음처리할 수 있도록 한 '음성다중방식TV오디오의 디지탈 전송시 에러감지 및 묵음처리회로'에 관한 것으로, 음성다중방식의 프로그램 전송시 필요한 TV오디오 전송 모드 데이타를 감시하여 재생출력하는 수단, 및 에러가 발생되면 묵음요구 신호를 발생시켜 오디오의 출력을 묵음시킬수 있도록 한 묵음처리 수단을 구비하고 있는 것을 특징으로 한다.The present invention silently processes audio data when an error occurs by detecting an error in 'TV audio transmission mode' information received without inserting a separate parity bit for error detection in digital transmission of audio multiplex JV audio data. The present invention relates to an error detection and silence processing circuit for digital transmission of voice multiplex TV audio, and to means for monitoring and reproducing and outputting TV audio transmission mode data necessary for transmitting a multiplex audio program. And a mute processing means for generating a mute request signal to mute the audio output.
