Abstract

본 발명은 일반 TV방송 시청시에 케이블 TV 컨버터나 TV 복합 송신기로부터 케이블 TV의 어느 하나의 키가 입력되거나 케이블 TV 방송 시청시에 케이블 TV이외의 키가 입력될 경우 사용자가 TV의 마이크로 프로세서에 임의로 설정한 고주파 채널 3 / 고주파 채널 4 / VCR / 기타 입력단자등과 연결되는 임의 설정 모드로 자동 절환되게 함으로써, 케이블 TV 방송과 일반 TV 방송 시청시의 채널 조작과정을 줄일 수 있도록 하여 사용자에게 편리함을 부여할 수있는 케이블 TV의 수신모드 자동절환방법에 관한 것인 바, 그 특징은 임의의 키입력이 있는 경우 현재의 수신모드를 체크하는 제 1단계와, 상기 제 1단계의 체크결과 일반 TV 수신모드이면 케이블 TV 컨버터 송신기 또는 TV 복합 송신기에서 들어오는 케이블 TV의 키값을 체크하여 케이블 TV의 키입력이 있을 경우 사용자가 저정한 임의 설정 입력단자를 선택할 수 있도록 튜너의 채널 선택 데이터를 케이블 TV 채널 수신 데이터로 변경하여 튜너로 전송하면서 동시에 A/V스위치 제어IC를 고주파 입력단자로 절환하는 제 2단계와, 상기 제 1단계에서 케이블 TV 수신모드이면 일반 TV 방송 채널키가 입력되는가를 체크하여 일반 TV의 채널키 입력이 있을 경우 튜너의 채널 선택 데이터를 케이블 TV로 넘어가기전 채널 데이터로 변경하여 튜너로 전송하면서 A/V 스위치 제어 IC를 고주파 입력단자로 절환하는 제 3단계로 이루어짐에 있다.According to the present invention, when one of the keys of the cable TV is input from the cable TV converter or the TV composite transmitter when watching a general TV broadcast, or a key other than the cable TV is input when the cable TV broadcast is watched, the user arbitrarily enters the microprocessor of the TV. By automatically switching to the arbitrary setting mode connected to the set high frequency channel 3 / high frequency channel 4 / VCR / other input terminal, it is possible to reduce the channel operation process in cable TV broadcasting and general TV broadcasting. The present invention relates to a method of automatically switching a reception mode of a cable TV, which is characterized by a first step of checking a current reception mode when there is an arbitrary key input, and the result of the check of the first step. Mode, the cable TV converter transmitter or the TV composite transmitter checks the key value of the cable TV to determine if there is a key input from the cable TV. A second step of changing the A / V switch control IC to a high frequency input terminal while simultaneously changing the channel selection data of the tuner to the cable TV channel reception data so that the user can select an arbitrarily set input terminal; In the first step, when the cable TV reception mode is input, it checks whether or not a general TV broadcasting channel key is input, and when there is a channel key input of the general TV, changes the channel selection data of the tuner to channel data before transferring to the cable TV, The third step is to switch the / V switch control IC to the high frequency input terminal.

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

제2도는 본 발명에 의한 TV 수신모드 자동절환방법의 일 실시예를 보인 동작 흐름도.2 is an operation flowchart showing an embodiment of a TV reception mode automatic switching method according to the present invention.

Claims (1)

임의의 키입력이 있는 경우 현재의 수신모드를 체크하는 제 1단계와, 상기 제 1단계의 체크결과 일반 TV 수신모드이면 케이블 TV 컨버터 송신기 또는 TV 복합 송신기에서 들어오는 케이블 TV의 키값을 체크하여 케이블 TV의 키입력이 있을 경우 사용자가 저정한 임의 설정 입력단자를 선택할 수 있도록 튜너의 채널 선택 데이터를 케이블 TV 채널 수신 데이터로 변경하여 튜너로 전송하면서 동시에 A/V스위치 제어IC를 고주파 입력단자로 절환하는 제 2단계와, 상기 제 1단계에서 케이블 TV 수신모드이면 일반 TV 방송 채널키가 입력되는가를 체크하여 일반 TV의 채널키 입력이 있을 경우 튜너의 채널 선택 데이터를 케이블 TV로 넘어가기전 채널 데이터로 변경하여 튜너로 전송하면서 A/V스위치 제어 IC를 고주파 입력단자로 절환하는 제 3단계로 이루어짐을 특징으로 하는 케이블 TV 수신모드 자동절환방법.The first step of checking the current reception mode if there is any key input, and the cable TV from the cable TV converter transmitter or the TV composite transmitter When there is a key input, the channel selection data of the tuner is changed to the cable TV channel reception data so that the user can select the arbitrarily set input terminal that is saved, and the A / V switch control IC is switched to the high frequency input terminal at the same time. In the second step and the first step, in the cable TV reception mode, it is checked whether a general TV broadcasting channel key is input, and when there is a channel key input of the general TV, the channel selection data of the tuner is changed to the channel data before moving to the cable TV. 3 steps to switch A / V switch control IC to high frequency input terminal while transmitting to tuner Cable TV reception mode automatic switching method. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
