그러나, 상기와 같은 종래기술에 있어서는 녹화 및 재생되는 테이프의 현재 위치가 어디까지 진행되고 있는지는 알 수 있으나, 녹화 및 재생된 시간, 즉 런닝 타임을 알 수 없다는 문제가 있다.However, in the prior art as described above, it is possible to know how far the current position of the tape to be recorded and reproduced is progressing, but there is a problem in that the time recorded and reproduced, that is, the running time is unknown.
즉, 종래에는 런닝타임을 기억시키고 이를 디스플레이 시키기 위한 장치가 없어 편집이나 녹화에 불편함을 가져오는 문제가 있다.That is, conventionally, there is a problem in that there is no device for storing and displaying the running time, which causes inconvenience in editing or recording.
본 발명은 이와 같은 종래기술의 문제점을 해결하기 위한 것으로, 재생 및 녹화시 지정된 각 구간의 런닝타임과 전체적인 런닝타임을 화면에 OSD(On Screen Display)로 표시하여 줄 수 있는 런닝타임 기록장치를 제공하는데 그 목적이 있다.The present invention is to solve the problems of the prior art, and provides a running time recording apparatus that can display the running time and the overall running time of each designated section during playback and recording on the screen by the OSD (On Screen Display) Its purpose is to.
상기 목적을 달성하기 위하여, 본 발명은, 스타트(Start), 앤드(End), 이레이즈(Erase) 신호를 마이컴에 출력시키기 위한 키신호 입력부와, 지정구간의 런닝타임을 산술하기 위한 감산기와, 구간 전체의 런닝타임을 산술하기 위한 가산기와, 서플라이 릴(Supply Reel) 펄스와 테이크 업(Take up) 릴 펄스를 출력시키는 데크와, 상기 키 신호 입력부, 감산기, 가산기, 데크로부터 신호를 입력받아 런닝타임을 화면에 디스플레이시키도록 제어하는 마이컴으로 이루어진 비디오 테이프의 런닝타임 기록장치를 제공한다.In order to achieve the above object, the present invention, a key signal input unit for outputting the start (Start), end (End), erase (Erase) signal to the microcomputer, a subtractor for calculating the running time of the specified section, An adder for arithmetic running time of the entire section, a deck for supplying supply reel pulses and take up reel pulses, and a signal input from the key signal input unit, a subtractor, an adder, and a deck for running. Provided is a running time recording apparatus of a video tape made of a microcomputer for controlling the display of time on a screen.
이하, 본 발명의 실시예를 첨부된 도면을 참조하여 상세히 설명하면 다음과 같다.Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.
제 1 도는 본 발명의 구성을 나타낸 블록도로서, 본 발명은 사용자에 의해 스타트, 앤드, 이레이즈 신호를 마이컴에 출력시키는 키신호 입력부(1)와, 지정구간의 런닝타임을 산술하는 감산기(2)와, 구간 전체의 런닝타임을 산술하는 가산기(3)와, 서플라이 릴 펄스와 테이크 업 릴 펄스를 출력시키는 데크(14)와, 상기 각 부로부터 신호를 입력받아 지정구간의 런닝타임과 구간 전체의 런닝타임을 메모리 시키고 화면에 디스플레이 시키도록 제어하는 마이컴(5)으로 구성된다.1 is a block diagram showing the configuration of the present invention. The present invention provides a key signal input unit 1 for outputting start, end, and erase signals to a microcomputer by a user, and a subtractor 2 for arithmetic running time of a designated section. ), An adder (3) for arithmetic running time of the entire section, a deck (14) for outputting supply reel pulses and take-up reel pulses, and a running time of the designated section and the entire section for receiving signals from the respective sections. It is composed of a microcomputer (5) for controlling the running time of the memory and display on the screen.
이와 같이 구성된 본 발명을 플로우챠트인 제 2 도와 OSD 상태를 설명하는 제 3 도를 참고하여 설명하면 다음과 같다.The present invention configured as described above will be described with reference to FIG. 2 as a flowchart and FIG. 3 illustrating an OSD state.
먼저, 본 발명에 있어서, 테이프의 스타트 위치 카운터 및 앤드 위치 카운터는 데크(4)의 서플라이 릴 펄스(PS)와 테크업 릴 펄스(PT)에서 산술된 기존의 리일(Real) 타임 카운터로 나타난다.First, in the present invention, the start position counter and the end position counter of the tape are conventional real time counters arithmetic from the supply reel pulse P S and the tech up reel pulse P T of the deck 4. appear.
런닝 타임 모드에서는, 제 3(a) 도의 와 같이 화면이 표시되며, 사용자가 스타트 키를 눌러 스타트 신호가 마이컴(5)에 입력되면 마이컴(5)에서 감산기(2)로 스타트 위치 카운터(CS) 신호가 출력된다(S1~S5단계).In the running time mode, a screen is displayed as shown in FIG. 3 (a), and when the user presses the start key and the start signal is input to the microcomputer 5, the microcomputer 5 starts the subtractor 2 and starts the start position counter C S. ) Signal is output (steps S1 to S5).
그러나, 스타트 키 신호가 입력되지 않으면 테이프 이젝트 여부와 이레이즈 키 신호 입력 여부를 판단하여 '예(Y)'인 경우 런닝 타임모드를 오프하고 노멀 모드를 유지한다(S6~S8단계).However, if the start key signal is not input, it is determined whether the tape is ejected or the erase key signal is input, and if yes, the running time mode is turned off and the normal mode is maintained (steps S6 to S8).
앤드키 신호가 마이컴(5)에 입력되면 마이컴(5)에서 감산기(2)로 앤드 위치의 리얼 타임 카운터(CE) 신호가 출력된다(S9, S10 단계).When the AND key signal is input to the microcomputer 5, the real time counter C E signal of the AND position is output from the microcomputer 5 to the subtractor 2 (steps S9 and S10).
그러나, 앤드 키 신호가 입력되지 않으면 테이프 이젝트여부와 이레이즈 키 입력 여부를 판단하여 '예(Y)'인 경우 런닝타임모드를 오프하고 노멀모드를 유지한다(S11~S13단계).However, if the AND key signal is not input, it is determined whether the tape eject and the erase key are input, and if yes, the running time mode is turned off and the normal mode is maintained (steps S11 to S13).
한편, 감산기(2)에서는 지정구간의 런닝타임(CR), 즉 CS-CE을 마이컴(5)에 출력시켜 이를 메모리시킨다(S14단계).On the other hand, the subtractor 2 outputs the running time (C R ) of the designated section, that is, C S -C E to the microcomputer 5 to store it (step S14).
또한, 이와 같이 마이컴(5)에 메모리된 감산기 출력인 CR이 가산기(3)로 출력되어 현재 프로(X-1) 구간까지의 전체 런닝타임(CRX-1= CR1+ CR2+ CR3+ … + CRN-1)과 가산됨으로써, 프로(X) 구간까지의 전체 런닝타임(CRX)으로 되어 다시 마이컴(5)에 입력되어진다.In addition, the CR, which is the subtractor output stored in the microcomputer 5, is output to the adder 3, and thus the total running time until the current pro (X-1) section (C RX-1 = C R1 + C R2 + C R3). +… + C RN−1 ), the total running time C RX up to the pro X section is input to the microcomputer 5 again.
이때, 제 3(b) 도와 같은 OSD가 화면에 표시됨과 아울러 전체 런닝타임이 마이컴(5)에 메모리된다(S15, S16단계). 그런후, 다음 프로의 진행을 위해 제 3(c) 도와 같은 OSD가 화면에 디스플레이된다(S17단계).At this time, the OSD as shown in FIG. 3 (b) is displayed on the screen and the entire running time is memorized in the microcomputer 5 (steps S15 and S16). Then, an OSD similar to the third (c) degree is displayed on the screen for the next pro to proceed (S17).
이상에서 설명한 바와 같이, 본 발명은 지정구간 런닝타임(CR)과 전체 런닝타임(C RX)이 마이컴(5)에 메모리 되면서 화면에 디스플레이되어 사용자가 지정하는 구간의 런닝타임을 표시하여 주므로 편짐 및 녹화가 더욱 편리해지는 효과가 있다.As described above, the present invention displays the running time of the section designated by the user while being displayed on the screen while the designated section running time (CR) and the total running time (C RX) are memorized in the microcomputer 5. The recording becomes more convenient.
