Abstract

본 발명은 텔레비젼의 사운드 모드 판별 방법 및 장치에 관한 것으로서, 본 발명에 따른 텔레비젼의 사운드 모드 판별 방법은 유럽 지역에서 D/K방식, B/G방식과 Ⅰ 방식의 신호를 동시에 수신해야 하는 경우에 각 방식의 음성 중간 주파 신호를 수신하여 사운드 모드를 판별하는 부분을 소프트웨어로 구현함으로써 하드웨어로 구현했을 때보다 효과적으로 경제적이라는 데 그 이점이 있고(대표도면:제5도), 또한 텔레비젼의 사운드 모드 판별 장치는 텔레비젼의 음성 중간 주파 수신부에 마이콤(10)과 메모리(20)를 추가 설치하여 사운드 모드를 판별해냄으로써, 채널 전환시에 발생하는 잡음을 제거시키는데 그 이점이 있다.The present invention relates to a method and apparatus for determining the sound mode of a television. The sound mode determination method for a television according to the present invention is a case in which a signal of the D / K, B / G, and I systems is to be simultaneously received in Europe. It is advantageous to implement the part that determines the sound mode by receiving the voice intermediate frequency signals of each method in software, which is more economical than the hardware implementation (representative drawing: Fig. 5), and also determines the sound mode of the television. The apparatus has an advantage of eliminating noise generated during channel switching by additionally installing the microcomputer 10 and the memory 20 in the audio intermediate frequency receiver of the television to determine the sound mode.
