본 고안은 티브이 시청자가 티브이를 몇시간정도 시청중인가를 알 수 있도록 한 "수직동기신호를 이용한 티브이 시청시간 표시회로"(본 출원인에 의해 선출원된 1982년 실용신안등록출원 제6272호)에 현재 시각발생회로를 결합한 회로에 관한 것이다.The present invention is in the "TV viewing time display circuit using a vertical synchronous signal" (TV Utility Registration Application No. 6262, filed by the applicant), which allows TV viewers to know how many hours they are watching TV. The present invention relates to a circuit incorporating a time generating circuit.
본출원인에 의해 선출원된 "수직동기신호를 이용한 티브이 시청시간 표시회로"에 있어서는 단순히 시청자가 시청개시로부터 시청종료까지의 시간을 자동으로 확인할 수 있도록 하고 있으나, 시청도중 그 주변에 시계류가 아무것도 없을때는 현재시각을 알 수 없어 매우 불편한 경우도 있다.In the "TV viewing time display circuit using a vertical synchronous signal" pre- filed by the present applicant, the viewer can automatically check the time from the start of the viewing to the end of the viewing. Sometimes it is very uncomfortable because the current time is unknown.
본 고안은 그 시청시간은 물론 간단한 조작으로 현재시각도 임의로 알 수 있도록 하여 시청자에게 편익을 제공하면서도 티브이 수상기를 다용도로 활용하기 위한 목적이 있다.The present invention aims to utilize the TV receiver as versatile while providing convenience to viewers by allowing them to know the present time arbitrarily as well as the viewing time.
이하에서 이를 상세히 설명하면 다음과 같다.This will be described in detail below.
제1도와 수평 및 수직동기신호(H, V-pulse)를 이용하여 티브이 수상기 화면상의 일정위치에 시간을 표시할 것인가를 결정하는 타이머(T1, T2), 2진카운터(BC(1))와 시간발생용 회로(A) 및 멀티플렉서(M1), 캐렉터제너레이터(CG), 쉬프트레지스터(SR), 클럭발생기(CL), 2진카운터(BC(2)), 타이머(T3, T4) 등으로 구성된 것에 있어서 상기 시간발생회로(A)에 별도의 발진기(OSC) 및 4비클럭발생기(BG)를 두고, 상기 펄스발생기(BG)와 멀티플렉서(M1) 사이에는 제1버퍼단(BF1)을 연결하며, 상기 디케이드 카운터(C1∼C4)와 멀티플렉서(M1) 사이에는 제2버퍼단(BF2)을 연결하고, 한편으로는 절환스위치(So)를 거쳐 제1버퍼단(BF1)에 전원을 공급함과 동시에 인버터(I)를 통하여 제2버퍼단(BF2)에 전원이 공급되도록 연결하여서 된 것이다.Timer (T 1 , T 2 ) and binary counter (BC (1)) for deciding whether to display time at a certain position on the TV receiver screen using the first and horizontal sync signals H and V-pulse. ), Time generation circuit (A) and multiplexer (M 1 ), collector generator (CG), shift register (SR), clock generator (CL), binary counter (BC (2)), timer (T 3 , T 4 ), etc., a separate oscillator (OSC) and four non-clock generators (BG) are provided in the time generating circuit (A), and a first buffer stage is provided between the pulse generator (BG) and the multiplexer (M 1 ). (BF 1 ) is connected, and a second buffer terminal BF 2 is connected between the decade counters C 1 to C 4 and the multiplexer M 1 , and on the other hand, a first switch is provided via a switching switch So. The power is supplied to the buffer stage BF 1 and connected to the second buffer stage BF 2 via the inverter I.
이러한 구성의 본 고안은 발진기(OSC)에서 1분마다 1개씩 펄스가 발생되어 그 펄스가 디케이드 카운터(C4)에 입력되면 디케이드카운터(C4)는 분을 계수하고, 여기서 발생한 케리(carry)가 디케이드카운터(C3)에 입력되어 10분단위를 나타내며, 마찬가지로 디케이드카운터(C2)는 시간단위를 계수하는 것으로서 시계회로가 동작한다.The design of such a construction is per 1 minute from the oscillator (OSC) is the one for the pulse generating the pulse is input to the decade counter (C 4) decade counter (C 4) is counting the minutes, in which occurred Kerry ( carry) is input to the decade counter C 3 to represent a ten minute unit. Likewise, the decade counter C 2 counts the time unit, and the clock circuit operates.
이때, 스위치(So)를 개방하고 스위치(S)를 닫으면 제2버퍼단(BF2)이 닫히면서 클리어펄스(clear pulse)가 발생하여 시간발생회로(A)의 디케이드 카운터(C1∼C4)를 모두 "0"로 바꾸고, 발진기(OSC)에서 나온 펄스 갯수로부터 시청시간을 계수하게 된다.At this time, when the switch So is opened and the switch S is closed, the second buffer stage BF 2 is closed and a clear pulse is generated so that the decade counters C 1 to C 4 of the time generating circuit A are generated. ) Are all set to "0", and the viewing time is counted from the number of pulses emitted by the oscillator (OSC).
그리고 스위치(So)를 닫으면 제1버퍼단(BF1)이 닫히고 제2버퍼단(BF2)은 개방되어 시청당시의 시각이 멀티플렉서(M1), 캐릭터 제너레이터(CG), 쉬프트레지스터(SR)를 통해 티브이 수상기 화면의 일정위치에 나타난다.When the switch So is closed, the first buffer stage BF 1 is closed and the second buffer stage BF 2 is opened so that the time at the time of viewing is maintained through the multiplexer M 1 , the character generator CG, and the shift register SR. The TV receiver appears at a certain position on the screen.
티브이를 꺼놓았을때도 4비트 클럭발생기(BG)와 발진기(OSC)는 계속 동작해서 별도의 시계로서 활용될 수 있으며, 시청시간이나 시각을 2진카운터(BC(2))로부터 발생된 데이타 선택신호로부터 멀티플렉서(M1)를 조정하여 캐랙터 제너레이터(CG)의 주소를 결정하게 된다.Even when the TV is turned off, the 4-bit clock generator (BG) and the oscillator (OSC) continue to operate and can be used as separate clocks, and select data generated from the binary counter (BC (2)) by viewing time or time. From the signal, the multiplexer M 1 is adjusted to determine the address of the character generator CG.
이러한 본 고안은 티브이 수상기를 이용하여 시청시간을 알 수 있으면서도, 그 시청도중에 현재 시각을 수시로 확인할 수 있고, 시청이 끝났더라도 별도의 시계로서 활용할 수 있는 매우 유익한 특징이 있다.The present invention has a very advantageous feature that can know the viewing time using the TV receiver, and can check the current time at any time during the viewing, and can be used as a separate watch even if the viewing is over.
