Description

암호를 이용한 텔레비전수상기의 영상 및 음성제어방법Video and Audio Control Method of Television Receiver Using Cryptography

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

제1도는 본 발명의 구동제어방법에 의한 텔레비전수상기의 회로도.1 is a circuit diagram of a television receiver according to the drive control method of the present invention.

Claims (1)

전원키를 누름에 따라 마이콤(4)이 암호(A)의 저장을 판별하여 암호가 저장되어 있을 경우에는 영상 및 음성소거 신호와 스위칭 신호를 출력하여 브라운관 (6G)에 온 스크린 문자만 표시되게하는 전원 온 루틴과, 상기의 암호(A)와 동일한 키신호가 입력될 경우 입력된 키신호가 암호(A)와 동일한지를 판별하여 동일한 경우에 영상 및 음성소거 신호와 스위칭신호의 출력을 차단하여 영상증폭부(6E)와 음성증폭부(6D)에 영상 및 음성신호를 출력하여 텔레비전수상기가 정상적인 동작을 하게 한 구동신호 온 루틴과, 암호 재입력키를 작동에 의해 설정되어 있는 암호(A)를 해제하고 키 신호의 입력에 의해 암호(B)를 재입력하는 암호 재입력루틴으로 제어함을 특징으로 한 암호를 이용한 텔레비전수상기의 영상 및 음성제어방법.By pressing the power key, the microcomputer (4) determines the storage of the password (A), and if the password is stored, outputs video and audio mute signals and switching signals so that only the screen characters on the CRT (6G) are displayed. When the same key signal as the password A is input, the power-on routine determines whether the input key signal is the same as the password A, and blocks the output of the video and audio mute signal and the switching signal in the same case. A drive signal on routine for outputting video and audio signals to the amplifying section 6E and the audio amplifying section 6D for the television receiver to operate normally, and the cipher code A set by operating the cipher re-entering key. And a password re-entering routine for releasing and re-entering the password B by input of a key signal. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
