본 고안은 VCR(Video Cassette Recorder)의 2개 이상의 방송에 따른 표시 장치에 관한 것으로 특히 다중 VCR(Mulit-VCR)추세에 따른 2개 이상의 방송방식을 취합하여 하나의 시스템으로 설계되는 모든 VCR에서 이를 표시하기 위한 방송방식 표시회로에 관한 것이다.The present invention relates to a display device according to two or more broadcasts of a VCR (Video Cassette Recorder). In particular, the present invention relates to two or more broadcast methods according to the multiple VCR (Mulit-VCR) trend. A broadcast method display circuit for displaying.

종래에는 단일 방송 시스템으로 설계가 진행되어 왔으며 또한 실제적으로 기술력이 뒷받침되지 못함으로 인하여 다중VTR방송방식을 전혀 설계되지 못하였다. 그러나 소비자의 욕구가 점차 다양화 됨에 따라서 그중 시스템에서 다중 시스템으로 진행 되고 있는 추세이며 이 시점에서 4가지 방송방식 (NTSC, PAL, SECAM, MESECAM)의 각 방송방식을 자동으로 절환되는 여러 가지 방법론을 선행되었으나 디스플레이 시키는 구체적인 방법이나 설계를 소프트웨어 적으로만 해결하고자 시도해 왔다. 그러나 소프트웨어적인 해결은 소프트웨어 기술이나 디스플레이만을 위한 스위칭 집적회로 사용이 불가능하게 되었는데 원인은 PCB(printed Circuit Board) 의 면적상태라든가 부품간 소화측면에서 어려움이 많기 때문이다.Conventionally, the design has been progressed to a single broadcasting system, and since the technology is not practically supported, the multiple VTR broadcasting system has not been designed at all. However, as the needs of consumers gradually diversify, the system is progressing from multiple systems to multiple systems, and at this point, various methodologies are automatically switched between four broadcasting methods (NTSC, PAL, SECAM, and MESECAM). Previously, attempts have been made to solve only the specific method or design of the display in software. However, software solutions have made it impossible to use switching integrated circuits only for software technology or displays because of the difficulty in the area of printed circuit boards (PCBs) and in terms of digestion between components.

이하 첨부된 도면에 의하여 본 고안을 상세히 설명하면 다음과 같다. 제1도는 본 고안의 회로도로서 NTSC(National Television System Committe)와 Pal(Phase Alternation by Line) ME-SCAM(의사 SEquence de Couleurs Amec Memoire) 방송방식을 판별하는 판별회로(1)와 SECAM과 PAL 방송방식을 판별하는 판별회로(2)를 구성하고, 상기 판별회로(1)는 저항(R9) (R10)을 통해 트랜지스터(TR6)의 베이스에 접속됨과 아울러 비교기(COM1)(COM2)의 비반전단자(+)에 각각 접속되며 상기 트랜지스터(TR2)의 콜렉터는 저항(R11)을 거쳐 전원단(B+)에 접속됨과 동시에 저항(R18)과 인버터(INV4)를 통하여 의사 SECAM 방송방식을 표시하는 발광다이오드(LED4)와 저항(R4)을 거쳐 전원단(B+)에 접속되고, 상기 반전단자(-)에 저항(R13)을 통해 전원단(B+)에 접속된 비교기(COM1)는 저항(R15)과 인버터(INV1)를 통하여 NISC 방송 방식을 표시하는 발광다이오드(LED1)와 저항(R1)을 거쳐 전원단(B+)에 접속된다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings. 1 is a circuit diagram of the present invention, and a discrimination circuit (1) for discriminating NTSC (National Television System Committe) and Pal (Phase Alternation by Line) ME-SCAM (Doctor SEquence de Couleurs Amec Memoire) broadcasting schemes, and SECAM and PAL broadcasting schemes. And a discriminating circuit 2 for discriminating the difference between the non-inverting terminals of the comparators COM1 and COM2. The discriminating circuit 1 is connected to the base of the transistor TR6 through the resistors R9 and R10. And a collector of the transistor TR2 is connected to a power supply terminal B + through a resistor R11 and at the same time displays a pseudo SECAM broadcasting scheme through a resistor R18 and an inverter INV4. (LED4) and via a resistor (R4) is connected to the power supply terminal (B +), the inverting terminal (-) of the comparator (COM1) connected to the power supply terminal (B +) through a resistor (R13) to a resistor (R15 ) and connected to the light emitting diode (LED1) and a power supply terminal via a resistor (R1) (B +) for displaying NISC broadcasting system via the inverter (INV1) .

한편 상기 판별회로(2)는 저항(R7)(R8)을 통하여 트랜지스터(TR1)의 베이스에 접속됨과 아울러 저항(R17)과 인버터(INV3)를 통하여 SECAM 방송방식을 표시하는 발광다이오드(LED3)와 저항(R3)을 거쳐 전원단(B+)에 접속되고, 상기 트랜지스터(TR1)의 콜렉터는 저항(R6)을 통해 전원단(B″)에 접속됨과 동시에 상기 앤드게이트(AND1)의 타측에 접속되며 상기 앤드게이트(AND1)는 저항(R16)과 인버터(INV2)를 통하여 PAL 방송방식을 표시하는 발광다이오드(LED2)와 저항(R2)을 거쳐 전원단(B+)에 각각 접속되도록 구성한다. 이하 이들의 작용효과를 설명한다.On the other hand, the determination circuit 2 is connected to the base of the transistor TR1 through the resistors R7 and R8, and the light emitting diode LED3 for displaying the SECAM broadcasting scheme through the resistor R17 and the inverter INV3; The resistor R3 is connected to the power supply terminal B + , and the collector of the transistor TR1 is connected to the power supply terminal B ″ through the resistor R6 and simultaneously connected to the other side of the AND gate AND1. The AND gate AND1 is configured to be connected to the power supply terminal B + through the light emitting diode LED2 indicating the PAL broadcast method and the resistor R2 through the resistor R16 and the inverter INV2. The effect of these will be described below.

VCR 시스템에 전원이 인가되고 첫째 NTSC 방송방식의 테이프를 사용한다면 NTSC/PAL/MESECAM 판별회로(1)가 컬러 캐리어(COLOR CARRLER)로서 컬러 상태를 판별하여 하이신호 출력을 내보낸다.If power is supplied to the VCR system and the first NTSC broadcasting tape is used, the NTSC / PAL / MESECAM discrimination circuit 1 discriminates the color state as a color carrier and sends out a high signal output.

이 하이신호는 저항(R9)(R10)을 통하여 트랜지스터(TR2)에 베이스에 인가됨과 동시에 비교기(COM1)(COM2)의 비반전단자(+)에 인가되며 상기 트랜지스터(TR2)는 도통되어 콜렉터 전류가 베이스로 접지되므로 이 콜렉터에 접속된 인버터(INV4)에는 로우신호가 인가되어 상기 인버터(INV4)는 하이신호를 출력 MESECAM 방송방식을 표시하는 발광다이오드(LED4)는 점등되지 못하며, 상기 비교기(COM1)는 상기 판별회로(1)의 출력전압이 비반전단자(-)의 전압보다 크기 때문에 출력신호는 하이신호 되어 인버터(INV1)를 통하여 로우신호가 되므로 NTSC 방송방식을 표시하는 발광다이오드(LED1)가 점등된다.The high signal is applied to the base of the transistor TR2 through the resistors R9 and R10 and simultaneously applied to the non-inverting terminal + of the comparator COM1 and COM2, and the transistor TR2 is turned on to collect the collector current. Since the signal is grounded to the base, a low signal is applied to the inverter INV4 connected to the collector so that the inverter INV4 outputs a high signal. The light emitting diode LED4 indicating the MESECAM broadcasting method cannot be turned on, and the comparator COM1 Since the output voltage of the discrimination circuit 1 is greater than the voltage of the non-inverting terminal (-), the output signal becomes high signal and becomes a low signal through the inverter INV1. Lights up.

그러나 상기 비교기(COM2)의 출력은 앤드게이트(AND1)에서 차단되어 그외의 발광다이오드들은 소등된다.However, the output of the comparator COM2 is blocked at the AND gate AND1 so that the other light emitting diodes are turned off.

둘째, MESECAM 방송방식일때는 상기 판별회로(1)의 출력기 로우신호가 되어 상기 트랜지스터(TR2)를 오프시키므로 콜렉터의 하이신호는 인버터(INV4)를 통해 로우신호가 되어 MESECAM 방송방식을 표시하는 발광다이오드(LED4)를 점등시킨다. 이때 상기 비교기(COM1)(COM2)에는 로우신호가 인가되므로 나머지 발광 다이오드들은 모두 소등된다. 셋째, 상기 테이프가 SECAM 방송방식이라면 SECAM/P AL 판별회로(2)의 출력인버터(INV3)에 인가되므로 상기 인버터(INV3)의 출력이 로우가 되어 SECAM 방송방식을 표시하는 발광다이오드(LED3)가 점등하게 되고, 상기 트랜지스터(TR1)는 도통되어 콜렉터 전류가 모두 에미터로 접지되므로 상기 앤드게이트(AND1)에 로우신호를 인가하여 나머지 발광다이오드들은 모두 소등된다.Secondly, in the MESECAM broadcasting method, the output signal of the discriminating circuit 1 becomes the low signal and turns off the transistor TR2. Therefore, the high signal of the collector becomes the low signal through the inverter INV4, thereby displaying the MESECAM broadcasting method. Turn on (LED4). At this time, since the low signal is applied to the comparator COM1 and COM2, all remaining light emitting diodes are turned off. Third, if the tape is a SECAM broadcasting method, since the tape is applied to the output inverter INV3 of the SECAM / P AL discrimination circuit 2, the output of the inverter INV3 becomes low so that the light emitting diode LED3 displaying the SECAM broadcasting method is provided. Since the transistor TR1 is turned on and the collector currents are all grounded to the emitter, all of the light emitting diodes are turned off by applying a low signal to the AND gate AND1.

넷째 PAL 방송방식일 경우는 상기 판별회로(1)의 중간신호 출력이 상기 트랜지스터(TR2)를 도통 시키지만 상기 비교기(COM1)의 출력은 로우신호로 만들고 상기 비교기(COM2)의 하이로 만들어 앤드게이트(AND1)에 역시 하이신호가 인가되어 상기 앤드게이트(AND1)의 하이출력신호는 인버터(INV2)를 통해 로우 신호를 만들므로 PAL 방송방식을 표시하는 발광다이오드(LED2)가 점등되고 그외의 발광다이오드들은 소등된다.In the fourth PAL broadcast mode, the intermediate signal output of the discrimination circuit 1 conducts the transistor TR2, but the output of the comparator COM1 is made low and the comparator COM2 is made high. The high signal is also applied to AND1), and the high output signal of the AND gate AND1 makes a low signal through the inverter INV2. Therefore, the LED LED indicating the PAL broadcasting method is turned on and the other LEDs are turned on. It goes out.

상기한 바와같이 본 고안은 여러종류의 방송방식을 표시하는데 이를 소프트웨어적인 해결방법과 스위치로회로의 사용을 배제하고 단순한 소자들과 비교기등을 이용하여 다중 시스템으로 설계되는 모든 VCR의 다중 방송방식 표시회로를 구현하는 장점이 있는 것이다.As described above, the present invention displays various types of broadcasting schemes, which excludes the software solution and the use of switch circuits, and displays the multiple broadcasting schemes of all VCRs designed as multiple systems using simple devices and comparators. There is an advantage to implementing the circuit.
