Abstract

이 발명은 위성방송 수신기에 있어서, 마이크로폰을 통하여 제공되는 특정화자의 아날로그 음성신호를 디지탈 음성신호로 변화하는 A/D 변환기와, 상기 A/D 변환기를 통하여 제공된 디지탈 음성신호를 처리하여 인식명령을 출력시키는 음성인식 시스템과, 상기 음성인식 시스템의 인식명령을 디지탈 신호로 처리하는 디지탈 시그날 프로세서와, 상기 디지탈 시그날 프로세서에 의해 신호 처리된 디지탈 신호를 아날로그 신호로 변환하는 D/A변환기와, 상기 D/A 변환기로부터 인가된 아날로그 신호에 따라 해당 대역에 따른 특정 채널의 방송신호를 선국하여 출력하는 튜너와, 상기 튜너로 부터 선국된 방송신호에 자막신호를 처리하는 온스크린 디스플레이와, 상기 온스크린 디스플레이어를 통하여 자막처리된 영상신호의 레벨을 일정하게 하는 제1 버퍼와, 상기 제1버퍼의 영상신호와 온스크린 디스플레이에서 직접 출력되는 음성신호를 하나의 출력신호로 결정하는 멀티플렉서와, 상기 멀티플렉서를 통하여 출력된 신호 레벨을 일정하게 하여 텔레비젼 또는 VTR에 출력하는 제2 및 제3버퍼로 구성된 음성인식 기능을 구비한 위성방송 수신기를 구현하였다.The present invention provides a satellite broadcasting receiver comprising: an A / D converter for converting an analog voice signal of a specific speaker provided through a microphone into a digital voice signal, and a digital voice signal provided through the A / D converter for processing a recognition command. A voice recognition system for outputting, a digital signal processor for processing a recognition command of the voice recognition system as a digital signal, a D / A converter for converting a digital signal processed by the digital signal processor into an analog signal, and the D A tuner that tunes and outputs a broadcast signal of a specific channel according to a corresponding band according to an analog signal applied from the / A converter, an on-screen display processing a subtitle signal to a broadcast signal tuned from the tuner, and the on-screen display A first buffer which makes the level of the subtitled video signal constant through A multiplexer for determining the video signal of the first buffer and the audio signal directly output from the on-screen display as one output signal, a second multiplexing signal level output through the multiplexer to be output to a television or a VTR; A satellite broadcasting receiver with a voice recognition function consisting of a third buffer is implemented.
