최근 비디오 정보시대를 맞이하여 컴퓨터 터미날등 각종 영상수상기의 사용이 대중화되고 있으나 종래의 영상수상기는 전원을 공급하고 신호원을 연결하여도 영상신호가 가해지지 않으면 화면이 어두운 상태로 있게 된 구조이기 때문에 영상신호가 가해져야만 어두운 화면에 영상출력이 나타나고 영상신호가 가해지기전에는 정상적으로 통전되고 있어도 신호원이 접합되 있는지의 여부를 화면에 의해 알 수가 없었으며, 여러가지 종류의 신호원이 연결된 구조인 경우에도 영상신호가 가해지기 전에는 어떠한 종류의 신호원이 연결되었는지를 화면에 의해 할 수가 없었다.Recently, the use of various video receivers such as computer terminals has been popularized in the video information age. When the video signal is applied, the video output appears on the dark screen and before the video signal is applied, it is impossible to know whether the signal source is connected even if it is normally energized. Before the video signal was applied, the screen could not tell what kind of signal source was connected.

본 고안은 종래의 영상수상기에서 위와 같은 결점을 해결하기 위하여 고안된 것으로서 전원이 공급되면 일반 테레비젼 수상기와 마찬가지로 라스터(raster)가 나타나도록 하며 여러가지의 영상신호가 연결되도록 되어 있는 경우에는 선택위치에 의하여 선택된 신호원을 색상으로 구분할 수 있도록 한 것으로서 이를 첨부된 도면에 의해 상세히 설명하면 다음과 같다.The present invention is designed to solve the above drawbacks in the conventional video receiver. When the power is supplied, the raster appears like a general TV receiver. The selected signal sources can be distinguished by color, which will be described in detail with reference to the accompanying drawings.

비디오앰프와 연결된 선택(또는 확인) 스위치(S1,S2,S3)에 다이오드(D2,D3,D4)와 가변저항(VR1)를 통해 트랜지스터(TR2)를 거쳐 트랜지스터(TR1)을 연결하고 트랜지스터(TR2)의 에미터와 트랜지스터(TR1)의 콜렉터의 사이에 저항(R2)을 트랜지스터 (TR1)의 베이스와 에미터의 사이에 저항(R4)과 콘덴서(C3)를 병열로 각각 연결하며 저항(R4)의 일단에는 저항(R1)을 거쳐 직류전원(B+)이 공급되게 하고 저항(R4)과 다이오드(D1) 저항(R3)의 병렬회로의 일단에 콘덴서(C1)를 거쳐 비디오신호 또는 영상신호원이 등기신호가 가해지도록 된 구조로 되어 있으며 미설명부호 C2는 교류성 잡음억제용 콘덴서이며, R, G, B는 각각 적색, 녹색, 청색 디스플레이 모니터 입력단에 연결된 본 회로의 출력단을 나타낸다.The selection (or confirmation) switches S 1 , S 2 , and S 3 connected to the video amplifiers pass through the transistors TR 2 through the diodes D 2 , D 3 , D 4 and the variable resistor VR 1 . TR1) the connection, and the transistor (TR 2) the emitter and the transistor (resistance between the base and the emitter of the transistor (TR 1) a resistor (R 2) between the collector of TR 1) (R 4) and a capacitor connect the (C 3) to byeongyeol and one end of the resistor (R 4) is through a resistance (R 1) causes the direct-current power supply (B +) is applied and the resistance (R 4) and a diode (D 1) resistance (R 3 ) Is a structure in which a video signal or a video signal source is applied to a registered signal through a capacitor C 1 at one end of a parallel circuit of the circuit), and an unexplained symbol C 2 is an AC noise suppression capacitor. Are the output stages of this circuit connected to the red, green and blue display monitor inputs, respectively.

위와 같이 된 본 고안은 콘덴서(C1)를 통해 비디오신호 또는 영상등기신호가 가해지면 다이오드(D1)를 통하여 트랜지스터(TR1)의 베이스에 부(-)전위가 가해지므로 트랜지스터(TR1)가 동작하지 않고 이에 따라 트랜지스터(TR2)도 구동되지 않으므로 트랜지스터(TR2)의 콜렉터와 가변저항기(VR1)는 0(zero) 전위가 되어 다이오드 (D2,D3,D4)로 인해 비디오앰프와는 역극성으로 되어 동작이 격리되게 되어 있으며, 신호가 입력되지 않으면 직류전원(B+)이 저항(R1,R4)에 의하여 분압되어 트랜지스터 (TR1)의 베이스는 정(+)전위, 정바이어스가 되어 트랜지스터(TR1)가 동작하므로 저항(R2)에 의해 트랜지스터(TR1)에 콜렉터 전류가 흘러 트랜지스터(TR2)의 정바이어스를 이루게 되므로 트랜지스터(TR2)가 구동되고 이에 따라 트랜지스터(TR2)의 콜렉터전류에 의하여 가변저항기(VR1)에 정(+)전위가 발생되므로, 가변저항기(VR1) 적절히 조정하여 선택스위치(S1,S2,S3)를 통하여 영상수상기에 적당한 레벨로 공급하여 주면 선택스위치(S1,S2,S3)의 접속에 의하여 선택된 신호원과 같은 색상으로 화면을 밝혀주게 된다.The present design as shown above is a capacitor (C 1), a video signal or image registration signal is applied when the diode unit to the base of the transistor (TR 1) through (D 1) via (-) electric potential is therefore applied to the transistor (TR 1) Does not operate and accordingly the transistor TR 2 is not driven and therefore, the collector of the transistor TR 2 and the variable resistor VR 1 become a zero potential, which is caused by the diodes D 2 , D 3 , and D 4 . It is reverse polarity with the video amplifier to isolate the operation.If no signal is input, the DC power supply B + is divided by the resistors R 1 and R 4 so that the base of the transistor TR 1 is positive (+). ) potential, it is the forward bias transistor (TR 1) is operated so that the collector current in the transistor (TR 1) by a resistor (R 2) flow formed the forward bias of the transistor (TR 2), so the transistor (TR 2), the driving Thus, the collector of transistor TR 2 Positive (+) potential is generated in the variable resistor VR 1 by the current flow. Therefore, the variable resistor VR 1 is appropriately adjusted and supplied to the image receiver at an appropriate level through the selection switches S 1 , S 2 , and S 3 . The main screen illuminates the screen in the same color as the signal source selected by the connection of the selection switches S 1 , S 2 and S 3 .

이처럼 본 고안은 비디오 또는 동기신호가 입력되지 않아도 전원을 연결하기만 하면 라스터에 의해 통전을 확인할 수 있고 신호원이 여러가지 종류인 경우 신호원 입력스위치와 본건 고안의 선택(또는 확인) 스위치(S1,S2,S3)의 연동에 의해 각기 다른 색상의 화면으로 선택된 산호원과 같은 색상을 나타나게 되어 사용자가 화면이 나타나기 전에 어떠한 신호원이 연결된 것인지를 알 수 있도록 한 유용한 고안이다.In this way, even if the video or sync signal is not input, you can check the power supply by the raster just by connecting the power source.In case of various kinds of signal sources, the signal source input switch and the selection (or confirmation) switch of the present invention (S) 1 , S 2 , S 3 ) It is a useful design that allows the user to know which signal source is connected before the screen is displayed by displaying the same color as the coral source selected by different colored screens.
