Abstract

본 발명은 노말 TV/테이블 TV/외부신호 선택방법에 관한 것으로, 일반적인 TV에서는 노말, 테이블 TV및 외부입력을 시청하기 위해 노말 TV 선택스위치와 튜너/외부입력 선택스위치를 동시에 조작하여야하는 문제점이 있었다. 본 발명은 모드 선택스위치를 하나의 스위치로 하여 그 모드선택스위치의 정환에 따라 노말, 케이블 TV 및 외부 입력모드를 체크하는 제1과정과, 상기 모드가 노말 TV 모드이면 데이타를 노말 TV 채널의 데이타로 선택하고 튜너에서 튜닝된 노말 TV 의 방송신호를 입력처리하는 제2과정과, 상기 모드가 케이블 TV이면 데이타를 케이블 TV채널의 데이타로 선택하고 튜너의 방송신호를 입력처리하는 제3과정과, 상기 모드가 외부입력 모드이면 외부의 신호를 입력처리하는 제4과정으로 이루어 방송모드를 선택할 수 있는 것이다.The present invention relates to a method of selecting a normal TV / table TV / external signal, and in general TV, a normal TV selection switch and a tuner / external input selection switch must be operated simultaneously in order to view normal, table TV, and external input. . The present invention provides a first process of checking a normal, a cable TV and an external input mode according to the switching of the mode selection switch by using the mode selection switch as one switch, and when the mode is the normal TV mode, the data is stored in the normal TV channel data. A second process of inputting and processing a broadcast signal of a normal TV tuned by a tuner, a third process of selecting data as data of a cable TV channel if the mode is cable TV, and inputting and processing a broadcast signal of a tuner; If the mode is an external input mode, a fourth process of input processing an external signal may be performed to select a broadcast mode.

Description

노말 TV/케이블 TV/외부신호 선택방법Normal TV / Cable TV / External Signal Selection

본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음Since this is an open matter, no full text was included.

제1도는 본 발명 노말 TV/케이블 TV/외부신호 선택시스템 구성도.1 is a block diagram of a normal TV / cable TV / external signal selection system of the present invention.

제2도는 제1도의 동작설명에 대한 신호흐름도로서, (가)는 모드선택 스위치의 절환에 따른 신호흐름도이고, (나)는 리모콘의 키이선택에 따른 신호흐름도이다.2 is a signal flow chart illustrating the operation of FIG. 1, (a) is a signal flow diagram according to the switching of the mode selection switch, and (b) is a signal flow diagram according to the key selection of the remote controller.

Claims (2)

방송 모드선택스위치 및 리모콘을 스캔하여 노말 TV, 케이블 TV 및 외부입력모드를 체크하는 제1과정과, 상기 체크한 모드가 노말 TV 모드이면 위상동기루프 데이타를 노말 TV 채널의 데이타로 선택하고 오디오처리부 및 위도/색도처리부를 제어하여 튜너에서 튜닝된 노말 TV의 음성과 영상신호를 입력처리하는 제2과정과, 상기 체크한 모드가 케이블 TV이면 위상동기루프 데이타를 케이블 TV 채널의 데이타로 선택하고 오디오처리부 및 휘도/색도처리부를 제어하여 튜너에서 튜닝된 케이블 TV의 음성 및 영상신호를 입력처리하는 제3과정과, 상기 모드가 외부입력 모드이면 노말 TV, 케이블 TV를 차단하고 외부의 음성 및 영상신호를 입력처리하는 제4과정으로 이루어짐을 특징으로 한 노말 TV/케이블 TV/외부신호 선택방법.The first step of checking the normal TV, cable TV and the external input mode by scanning the broadcast mode selection switch and the remote control, and if the checked mode is the normal TV mode, the phase synchronization loop data is selected as the data of the normal TV channel and the audio processor And a second process of inputting audio and video signals of a normal TV tuned by a tuner by controlling a latitude / color processing unit. If the checked mode is cable TV, phase synchronization loop data is selected as data of a cable TV channel, and audio is output. A third process of inputting and processing audio and video signals of the cable TV tuned by the tuner by controlling the processing unit and the luminance / chromatic processing unit; and when the mode is an external input mode, the normal TV and the cable TV are blocked and the external audio and video signals are controlled. Normal TV / cable TV / external signal selection method characterized in that consisting of a fourth process for input processing. 제1항에 있어서, 리모콘의 키이데이타 입력시 현재 디스플레이 방송모드 상태를 체크하여 그 체크한 방송모드에 따라 노말 TV모드, 케이블 TV모드 및 외부입력모드로 순차적으로 변화하여 디스플레이함을 특징으로 한 노말 TV/케이블 TV/외부신호 선택방법.According to claim 1, When the key data input of the remote control to check the current display broadcast mode status according to the normal broadcast mode, the cable TV mode and the external input mode according to the checked broadcast mode to display sequentially How to select TV / Cable TV / External Signal. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
