Abstract

본 발명은 디스크드라이브에 삽입된 디스크의 종류에 따라 자동적으로 텔레비젼전원을 온시키면서 텔레비젼의 텔레비젼/비디오절환수단을 절환할 수 있도록 된 오디오/비디오시스템에서의 전원제어장치를 제공한다.The present invention provides a power supply control apparatus in an audio / video system that can switch television / video switching means of a television while automatically turning on the television power supply according to the type of a disc inserted in the disk drive.

이를 위해 본 발명은, VCD 플레이어의 여리가지 기능에 대한 키입력수단으로 되는 리모콘송신기(1)와, 이 리모콘송신기(1)의 조작에 따라 전원이 온/오프되는 VCD 전원부(2), 상기 리모콘송신기(1)의 전원스위치조작으로 활성화되어 디스크드라이브(4)로 소정의 제어신호를 송출해서 상기 디스크드라이브(4)에 삽입된 디스크의 종류를 판별하여 화상정보가 기록된 디스크인 경우에는 그 출력포트(P1, P2)로부터 텔레비전시스템의 제2전원스위치(S12)온시키면서 제2텔레비젼/비디오절환스위치(S22)를 온시키는 소정의 제어신호(C1, C2)를 송출하는 제2마이콤(3) 및, VCD나 CD등과 같은 디스크가 삽입되는 디스크드라이브(4)로 구성된 VCD플레이어와; 제1 및 제2전원스위치(S1, S2)와 제1 및 제2텔레비젼/비디오절환스위치(S2, S22)에 소정의 스캔펄스를 송출하여 상기 각각의 스위치가 사용자나 상기 VCD플레이어의 제2마이콤(3)으로부터의 제어신호(C1, C2)에 의해 온되는 경우 텔레비젼전원부(6)를 온시킴과 더불어 텔레비젼모드를 비디오모드로 절환하는 제1마이콤(5), 사용자에 의해 인위적으로 온/오프제어되는 제1전원스위치(S1), 이 제1전원스위치(S1)와 병렬로 접속되고 상기 VCD 플레이어의 제2마이콤(3)으로부터 소정의 제어신호(C1)를 인가받아 온되는 제2전원스위치(S12), 사용자에 의해 인위적으로 텔레비젼/비디오모드로 절환되는 제1텔레비젼/비디오절환스위치(S2), 이 제1텔레비젼/비디오절환스위치(S2)와 병렬로 접속되고 상기 VCD 플레이어의 제2마이콤(3)으로부터 소정의 제어신호(C2)를 인가받아 온되어 비디오모드를 자동 절환되는 제2텔레비젼/비디오절환스위치위치(S22)로 구성된 텔레비젼시스템으로 이루어지낟.To this end, the present invention provides a remote control transmitter 1 serving as a key input means for various functions of a VCD player, a VCD power supply unit 2 that is powered on / off according to an operation of the remote control transmitter 1, and the remote controller. In the case of a disc which is activated by a power switch operation of the transmitter 1 and sends a predetermined control signal to the disc drive 4 to determine the type of disc inserted in the disc drive 4 and the image information is recorded thereon. A second microcomputer 3 which transmits predetermined control signals C1 and C2 for turning on the second television / video switching switch S22 while turning on the second power switch S12 of the television system from the ports P1 and P2; And a VCD player composed of a disc drive 4 into which a disc such as a VCD or CD is inserted; A predetermined scan pulse is sent to the first and second power switches S1 and S2 and the first and second television / video switching switches S2 and S22 so that each switch is a user or a second microcomputer of the VCD player. When turned on by the control signals C1 and C2 from (3), the first microcomputer 5 which turns on the television power supply 6 and switches the television mode to the video mode, is artificially turned on / off by the user. The first power switch S1 to be controlled, the second power switch connected in parallel with the first power switch S1 and receiving a predetermined control signal C1 from the second microcomputer 3 of the VCD player. (S12), a first television / video switching switch S2 artificially switched to a television / video mode by a user, connected in parallel with the first television / video switching switch S2, and a second microcomputer of the VCD player. A predetermined control signal C2 is applied from (3) and turned on A television system composed of a second television / video switching switch position (S22) which automatically switches the video mode.
