본 발명은 더블 데크 VCR의 예약녹화방법에 관한 것으로서, 더욱 상세하게는 예를 들면 1/2인치 VCR부에서 못다한 예약녹화를 8mm VCR부에서 이어서 녹화할 수 있도록 한 더블 데크 VCR의 예약녹화방법에 관한 것이다.The present invention relates to a reservation recording method of a double deck VCR, and more particularly, to a reservation method of a double deck VCR in which a reservation recording that cannot be performed in a 1/2 inch VCR section can be subsequently recorded in an 8 mm VCR section. It is about.
제1도는 일반적인 VCR의 개략 구성도를 도시한 것으로, 각종 키입력을 위한 키부(1), 시스템을 전반적으로 제어하는 마이컴(2), 위상 및 속도를 제어하는 서보부(3), 데크부(4) 등으로 구성되며, 이러한 시스템에서 수행되는 오토예약녹화는 제2도의 플로우 챠트에 따른다.1 is a schematic configuration diagram of a general VCR, which includes a key unit 1 for various key inputs, a microcomputer 2 for overall control of the system, a servo unit 3 for controlling phase and speed, and a deck unit ( 4) and the like, and auto reservation recording performed in such a system follows the flowchart of FIG.
이는 현재 정상속도(이하, SP라 칭함)로 오토예약녹화중이고 테이프의 남은 양이 판단되었다면(S1),(S2)예약녹화시간과 테이프의 남은 양에 따른 남은 시간과 비교하여 예약녹화시간이 크다면 다시 예약녹화시간과 3배 속도(이하, EP라 칭함)로 계산된 테이프의 남은 시간과 비교를 한다(S3),(S4).If the current recording is in auto reservation at normal speed (hereinafter referred to as SP) and the remaining amount of tape is judged (S1), (S2) the reserved recording time is larger than the remaining time according to the remaining recording time and the remaining amount of tape. When compared to the remaining time of the tape calculated by the reservation recording time and triple speed (hereinafter referred to as EP) (S3) and (S4).
만약, 예약녹화시간이 크거나 같다면 EP로 절환하게 되고 예약녹화시간이 작다면 그대로 SP로 수행을 하게 된다. 여기서, 예약녹화시간이 EP로 계산된 테이프의 남은 양보다 클때 EP로 예약녹화를 계속해서 수행을 하다가 테이프의 앤드센서(End Sensor)를 감지하면 마이컴(2)에서는 자동 되감기(REW)를 수행하고 예약녹화를 종료하게 된다(S5-S7).If the reservation recording time is greater than or equal to EP, it is switched to EP. If the reservation recording time is small, it is performed as SP. Here, when the reservation recording time is larger than the remaining amount of the tape calculated by EP, the recording continues with EP and when the end sensor of the tape is detected, the microcomputer 2 performs automatic rewinding. Reservation recording is terminated (S5-S7).
이를 예를 들어 설명하면 예약녹화시간이 2시간이고 테이프의 남은 양은 30분일 경우 오토예약녹화가 시작될 경우 VCR은 SP로 녹화를 하려다가 예약녹화시간이 테이프의 남은 시간보다 크기 때문에 다시 예약녹화시간 2시간과 EP로 계산된 테이프의 남은 시간(1시간 30분)과 비교를 하여 예약녹화시간이 크기 때문에 EP로 절환하여 녹화를 한다.For example, if the scheduled recording time is 2 hours and the remaining amount of tape is 30 minutes, if auto recording is started, the VCR will try to record with the SP, and then schedule recording time is again 2 hours because the recording time is larger than the remaining time of the tape. Compared with the remaining time (1 hour 30 minutes) of the tape calculated with the EP, the recording time is switched to EP because the reservation recording time is large.
그리고 1시간 30분후 테이프의 앤드 센서를 만나면 VCR은 자동 되감기를 하고 예약 녹화를 종료한다.After 1 hour and 30 minutes, the VCR automatically rewinds and ends scheduled recording.
따라서 상기와 같은 종래의 기술에서는 예약녹화시간이 EP로 계산된 테이프의 남은 시간보다 클때 테이프의 남은 시간보다 예약녹화시간이 큰 만큼의 시간을 예약녹화를 할 수 없게 되는 문제점이 있었다.Therefore, in the conventional technology as described above, when the reservation recording time is larger than the remaining time of the tape calculated by EP, there is a problem that the reservation recording cannot be made as much as the reservation recording time is larger than the remaining time of the tape.
본 발명은 이러한 문제점을 해결하기 위한 것으로, 본 발명의 목적은 더블 데크 VCR에서 제1 VCR부의 EP로 계산된 테이프의 남은 시간이 예약녹화시간보다 작은 경우 제1 VCR부에서 못다한 시간은 제2 VCR부에 이어서 예약녹화를 하도록 한 더블 데크 VCR의 예약녹화방법을 제공함에 있다.SUMMARY OF THE INVENTION The present invention has been made to solve this problem, and an object of the present invention is that when the remaining time of the tape calculated by EP of the first VCR unit in the double deck VCR is less than the reserved recording time, the time less than the first VCR unit is less than the second VCR unit. This section provides a reservation method of a double-deck VCR for reservation recording.
이러한 목적을 달성하기 위한 본 발명의 특징은 SP로 제1 VCR부에서 오토예약녹화중 테이프의 남은 시간과 예약녹화시간을 비교하는 제1단계를 수행하고, 테이프의 남은 시간이 예약녹화시간보다 작을 경우 예약녹화시간을 EP로 계산된 테이프의 남은 시간과 비교하는 제2단계를 수행하며, 상기 제2단계에서의 비교결과 EP로 계산된 테이프의 남은 시간이 예약녹화시간보다 작을 경우 제1 VCR부의 테이프의 남은 시간이 일정시간 이전까지 EP로 예약녹화를 수행하는 제3단계를 수행하고, 상기 제3단계에서 제1 VCR부의 테이프의 남은 시간이 일정시간 이전이면 제1 VCR부은 자동 되감기를 수행하고 제2 VCR부는 앤드 센서 감지 및 예약녹화종료시까지 예약녹화를 수행한 후 자동 되감기를 수행하는 제4단계를 수행하여 이루어지는 더블 데크 VCR의 예약녹화방법에 있다.A feature of the present invention for achieving this object is to perform a first step of comparing the remaining time of the tape during the auto-reservation recording and the reserved recording time with the SP in the first VCR unit, and the remaining time of the tape is smaller than the reserved recording time. In the case of performing the second step of comparing the reservation recording time with the remaining time of the tape calculated as EP, and if the remaining time of the tape calculated as EP as the comparison result in the second step is less than the reservation recording time, The third step of performing a reservation recording to the EP until the remaining time of the tape is a predetermined time. If the remaining time of the tape of the first VCR unit is earlier than the predetermined time, the first VCR unit automatically rewinds. The second VCR performs the fourth step of performing the automatic rewind after performing the scheduled recording until the end sensor is detected and the scheduled recording ends. have.
이하, 본 발명의 바람직한 일실시예를 첨부도면을 참조로 하여 상세히 설명한다.Hereinafter, with reference to the accompanying drawings, a preferred embodiment of the present invention will be described in detail.
제3도는 본 발명에 따른 더블 데크 VCR의 예약녹화방법을 수행하기 위한 플로우 챠트로써, 제1도와 같은 일반적인 더블 데크 VCR에서 수행된다.3 is a flowchart for performing a reservation recording method of a double deck VCR according to the present invention, and is performed in a general double deck VCR as shown in FIG.
이는 현재 SP 속도로 오토예약녹화중이고 테이프의 남은 양에 따른 남은 시간이 판단되었다면 예약녹화시간과 테이프의 남은 시간을 비교하여 예약녹화시간이 테이프의 남은 시간보다 크다면 다시 예약녹화시간과 EP로 계산된 테이프의 남은 시간과 비교를 한다(S11-S14).If the current recording time is SP during auto reservation and the remaining time according to the remaining amount of tape is judged, the reservation recording time is compared with the remaining time of the tape. The remaining time of the recorded tape is compared (S11-S14).
만약, 예약녹화시간이 EP로 계산된 테이프의 남은 시간보다 크거나 같다면 녹화속도를 EP로 절환하여 녹화를 계속해서 수행하게 된다(S15).If the reserved recording time is greater than or equal to the remaining time of the tape calculated as EP, the recording speed is switched to EP to continue recording (S15).
그리고 예약녹화시간이 EP로 계산된 테이프의 남은 시간보다 크다면 EP로 예약녹화를 수행하다가 테이프가 끝나기 일정시간(예 : 1분,3분)전이 되면 제1 VCR부는 자동 되감기를 수행하고 제2 VCR부는 예약녹화를 수행한다(S16),(S17). 이때 상기 제1 VCR부의 테이프가 끝나기 일정시간전 만큼 제1 VCR부와 제2 VCR부에 예약녹화되는 프로그램이 오버랩된다.If the reservation recording time is greater than the remaining time of the tape calculated as EP, if the reservation recording is performed in EP and before the end of the tape (for example, 1 minute, 3 minutes), the first VCR unit automatically rewinds and the second The VCR unit performs reserved recording (S16) (S17). At this time, a program that is reserved for recording by the first VCR unit and the second VCR unit overlaps a predetermined time before the tape of the first VCR unit ends.
그리고 예약녹화종료인가를 판단하여(S18) 예약녹화종료이면 제2 VCR부는 자동 되감기를 수행하고 예약녹화를 종료하며(S20), 예약녹화종료가 아니면 제2 VCR부의 앤드 센서를 감지하였는가를 판단한다(S19).If it is determined that the reservation recording is terminated (S18), if the reservation recording is finished, the second VCR unit automatically rewinds and terminates the reservation recording (S20). If not, the second VCR unit determines whether the end sensor of the second VCR unit is detected. (S19).
상기 단계(S19)에서 제2 VCR부의 앤드 센서가 감지되지 않았다면 아직 8mm VCR의 테이프가 끝나지 않은 것이므로 상기 단계(S18)로 진행하고, 제2 VCR부의 앤드 센서가 감지되면 상기 단계(S20)를 수행한다.If the end sensor of the second VCR unit is not detected in the step S19, the tape of the 8 mm VCR is not finished yet. Therefore, the process proceeds to the step S18. When the end sensor of the second VCR unit is detected, the step S20 is performed. do.
이상에서 살펴본 바와 같이 본 발명은 더블 데크 VCR이라는 점을 이용하여 제1 VCR부에서 테이프의 부족으로 못다한 예약녹화를 제2 VCR부에서 이어서 할 수 있게 되므로 사용자는 제2 VCR부에 들어 있는 테이프의 양만큼 원하는 예약녹화를 더 할 수 있게 된다.As described above, according to the present invention, since the double-decker VCR allows the recording of the second VCR unit to be reserved by the second VCR unit, which can not be performed due to lack of tape in the first VCR unit. You can add as many reservations as you want.
