Abstract

본 발명은 수신된 방송프로그램을 분류하고, 영상신호에 실려있는 한국형 간단 예약녹화 시스템(KBPS) 데이타를 슬라이스하여 상기 방송프로그램에 따라 고음 또는 저음등의 음레벨을 자동전환하고, 사운드 모드에 따라 사운드를 오프, 모노, 스테레오 모드로 자동전환 하도록 한 사운드 모드 자동 전환 방법에 관한 것으로, 종래 사운드 모드 전환 장치는 수신된 방송프로그램에 따라 고음 및 저음 레벨 조절과 방송서라운드 모드를 수동작에 의해 변경시켜야 하는 불편한 문제점이 있었다.The present invention classifies received broadcast programs, slices Korean simple reservation recording system (KBPS) data contained in a video signal, and automatically switches sound levels such as high or low sounds according to the broadcast programs, and sounds according to sound modes. The present invention relates to a sound mode automatic switching method for automatically switching to off, mono, or stereo mode. The conventional sound mode switching device has to adjust the high and low sound level and broadcast surround mode by manual operation according to a received program. There was an uncomfortable problem.

본 발명은 이와 같은 종래 문제점을 해결하기 위하여 IF처리부에서 방송프로그램을 분류한 후 영상신호에 실려있는 KBPS 데이타를 슬라이스하여 고음 및 저음등의 음레벨을 자동전환시키고 사운드 모드에 따라 방송 사운드 모드를 오프/모노/스테레오 모드로 자동전환되도록 한 것으로, TV 및 영상기기에 적용한다.In order to solve the conventional problems, the present invention classifies broadcast programs in an IF processor and slices KBPS data contained in an image signal to automatically switch sound levels such as high and low sounds, and turns off the broadcast sound mode according to the sound mode. Automatically switch to Mono / Stereo mode and apply to TV and video equipment.

Claims (1)

영상신호의 수직귀선기간에 실려있는 KBPS 데이타를 검출하여 현재방송프로그램 분류 데이타와 사운드 모드 데이타를 디코딩하는 제1과정과, 디코딩된 프로그램 데이타에서 뉴스, 드라마, 영화, 음악데이타 등을 분류하여 고음 및 저음의 레벨값을 설정한 후 서라운드를 온/오프 설정하여 세팅시키는 제2과정과, 상기 제2과정의 세팅결과 서라운드가 오프로 설정되어 있으며 서라운드 오프 모드를 세팅한 후 세팅된 고음, 저음 서라운드 데이타를 사운드 처리부로 출력하는 제3과정과, 상기 제2과정의 세팅결과 서라운드가 온으로 설정되어 있으면 온된 서라운드 모드를 판단하여 모노모드이면 서라운드 모드를 모노로 세팅하고 서라운드 모드가 스테레 오 모드이면, 상기 서라운드 모드를 스테레오로 세팅한 후 세팅된 고음, 저음 서라운드 데이타를 사운드 처리부로 출력하는 제4과정으로 이루어진 사운드 모드 자동 전환 방법.The first process of detecting KBPS data contained in the vertical retrace period of the video signal and decoding current program classification data and sound mode data, and classifying news, drama, movie, music data, etc. from the decoded program data, A second step of setting the level of the bass and then setting the surround on and off, and the setting result of the second step, the surround is set to off and the high and low surround data set after setting the surround off mode. In a third process of outputting to the sound processing unit, and if the setting result of the second process surround is set to on, judging the on the surround mode is set to mono mode if the surround mode is set to mono and if the surround mode is stereo mode, After the surround mode is set to stereo, the high and low surround data is set. The sound mode automatic switching method comprising a fourth step of outputting to the processor. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
