Abstract

The syncro editing method includes the steps of checking a playback mode of a VCP by comparing a radio frequency envelope signal detected when a VCR records a reproducing video signal of the VCP with a reference voltage signal, stopping an operation of the VCR if the compared value is larger than a constant value and the syncro editing signal is the ON state at the CUE/REV, and converting an operation of the VCR to the recording mode if the compared value is smaller than the constant value at the standard relay mode after skipping. As a result, the convenience of the syncro editing is achieved.

본 발명은 브이씨알의 트윈시스템 녹화편집수행에 관한 것으로, 특히 비디오 신호의 고주파 포락신호를 검출함에 따라 변속재생 및 무신호를 감지하여 서보제어부를 통해 녹화편집(Syncro Edit)을 수행하는 브이씨알의 트윈시스템 녹화편집수행방법 및 그 장치에 관한 것이다.The present invention relates to performing a twin system recording and editing of V-Cal. In particular, the present invention relates to a V-Cal which performs a syncro editing through a servo controller by detecting a shift playback and a no-signal according to detecting a high frequency envelope signal of a video signal. The present invention relates to a twin system recording and editing method and apparatus therefor.

제2도는 종래 브이씨알의 트윈시스템 모드제어부의 회로도로서 이에 도시한 바와같이, 일측에 재생신호(PB)가 접속되고 타측에 녹화편집시작신호(SYE)가 접속된 앤드게이트(AN1)의 출력이 일측에 접속된 앤드게이트(AN2)의 타측에 화상정지신호(SST)를 접속하고, 일측에 족화신호(SREC)가 접속되고 타측에 녹화편집대기신호(SSB)가 접속된 앤드게이트(AN3)의 출력이 일측에 접속된 앤드게이트(AN4)의 타측에 상기 앤드게이트(AN12)이 출력을 접속하여, 상기 앤드게이트(AN4)에서 모드중지신호(SPA)가 출력되게 구성된 것으로, 이와같은 종래회로의 동작과정을 제1도 브이씨알의 트윈시스템 구성도, 제3도 녹화편집시 테이프의 상태도를 참조하여 설명하면 다음과 같다.Second turn conventionally a circuit diagram of the V CR twin system mode control of the steps shown as this, connected with the reproduction signal (PB) on one side, and output of the record to the other editing start signal (SYE) is connected to the AND gate (AN 1) An end to which an image stop signal S ST is connected to the other side of the AND gate AN 2 connected to one side, a foot signal S REC is connected to one side, and a recording edit wait signal S SB is connected to the other side. The AND gate AN 12 connects the output to the other side of the AND gate AN 4 having the output of the gate AN 3 connected to one side thereof, so that the mode stop signal S PA is generated at the AND gate AN 4 . The operation of the conventional circuit will be described with reference to the twin system configuration of FIG. 1 and the state diagram of the tape during recording and editing.

일반적으로 브이씨알의 트윈시스템에 적용되는 녹화편집기능(Syncro Edit)은 두가지방식(A, B)이 채택되고 있으며 하나의 방식(B)은 또다른 방식(A)과 녹화편집기능을 수행하는 원리는 같으나 매스터측이 브이씨알(VCR)이고 슬래브(Slove)측이 브이씨피(VCP)측으로서 마이컴이 제어하는 송, 수신부가 다르다.In general, two methods (A and B) are adopted for the recording edit function (Syncro Edit) applied to the twin system of BCAL, and one method (B) performs another method (A) and the recording editing function. Although the master side is VCR and the slab side is VCP side, the transmission and reception sections controlled by the microcomputer are different.

먼저, 트윈시스템용 리모콘(R/C)으로 비이씨피(VCP)를 재생모드(Play)로 하고 브이씨알(VCR)을 녹화모드(REC)로 하여 녹화편집기능(Syncro Edit)을 수행하면 브이씨피(VCP)의 고전위의 재생신호(PB)가 일측에 출력된 앤드게이트(AN1)는 인에이블 상태가 되고, 제3도 (a), (b)에 도시한 바와같이 비디오테이프가 재생되어 브이씨알(VCR)에 녹화될때 녹화편집대기신호(SSB)와 녹화신호(SREC)가 고전위로 입력된 앤드게이트(AN3)는 고전위를 앤드게이트(AN4)의 일측에 출력하여 인에이블 상태가 되게 한다.First of all, if you use the twin system remote controller (R / C) to play VCP in Play mode and VCR to REC in REC mode, then perform Syncro Edit. The AND gate AN 1 on which the high potential reproduction signal PB of the VCP is output on one side becomes an enable state, and the video tape is reproduced as shown in FIGS. 3A and 3B. When recorded on VCR, the AND gate (AN 3 ) inputted with the recording edit standby signal (S SB ) and the recording signal (S REC ) at high potential outputs the high potential to one side of the AND gate (AN 4 ). To be enabled.

이때, 재생 및 녹화를 수행하는 중에 브이씨피(VCP)의 비디오테이프에 미녹화부분이 있을때 그 장면전에서 상기 브이씨피(VCP)는 녹화편집시작신호(SYE)를 고전위로 출력하고 미녹화부분의 처음에서 스틸신호(Still)를 고전위로 하면 앤드게이트(AN1)이 고전위를 출력하여 타축에 고전위인 스틸신호(Still)가 인가된 앤드게이트(AN2)가 고전위를 출력하므로 앤드게이트(AN4)가 고전위인 모드중지신호(SPA)로 브이씨알(VCR)의 녹화동작을 중지시킨다.At this time, when there is an unrecorded portion on the video tape of the VCP during playback and recording, the VCP outputs the recording edit start signal SYE at a high potential before the scene. When the still signal (Still) at the high potential at the beginning, the AND gate (AN 1 ) outputs a high potential, and the AND gate (AN 2 ) to which the steel signal (Still) having a high potential is applied to the other axis outputs a high potential. AN 4 ) stops the recording operation of the VCR with the mode stop signal S PA having a high potential.

따라서, 브이씨알(VCR) 중지모드(PAUSE) 상태에서 녹화편집대기신호(SSB)를 저전위로 한 후 브이씨피(VCP)를 감기모드(FF)로 하여 미녹화부분을 지난 후 스틸모드(Still)로 하고 녹화편집시작신호(SYE)를 저전위로 하여 비디오테이프의 녹화된 부분의 브이씨피(VCP)와 브이씨알(VCR)의 재생 및 녹화동작을 계속 수행한다.Therefore, after the recording edit standby signal S SB is set to the low potential in the VCR pause mode PAUSE, the VCP is set to the winding mode FF, and after the unrecorded portion, the still mode The recording and editing start signal SYE is set at the low potential, and the playback and recording operations of the VCP and VCR of the recorded portion of the video tape are continued.

그러나, 이와같은 종래 기술방식의 녹화편집기능으로 비디오 테이프의 녹화편집을 수행할때 브이씨알의 트윈시스템 리모콘의 제어에 의해 재생화면의 스킵(Skip)후 복사녹화를 수행하기까지 키동작이 어렵고 번거로우며 브이씨피측의 재생화면을 녹화할 부분에서 놓쳤을 경우 녹화편집기능에서는 역재생상태에서 녹화가 불가능할뿐 아니라 브이씨피와 브이씨알을 별도의 잭과 케이블로 연결하여야 하고 리모콘 제어방식에서만 녹화편집기능이 가능한 문제점이 있었다.However, when performing the recording editing of videotape with the prior art recording editing function, the key operation is difficult and cumbersome until the copying of the playback screen is performed after the skip of the playback screen by the control of VRT's twin system remote controller. If you missed the playback screen on the VPC side, you can not record in the reverse playback mode in the recording edit function, but you need to connect VCPI and VRC with separate jacks and cables. There was a possible problem.

본 발명은 이러한 문제점을 감안하여 별도의 케이블을 접속하지 않고 변속재생시 또는 무신호상태에서 브이씨알이 녹화편집기능(Syncro Edit) 수행모드라면 브이씨피의 고주파 포락신호를 검출하여 기준전압과 비교한 후 설정치 이하이면 녹화중지상태로 하고 설정치 이상이되면 녹화기능을 수행하며, 역재생모드에서 녹화편집기능 상태이면 원하는 부분의 화면을 녹화하는 트윈시스템 브이씨알의 녹화편집수행방법 및 그 장치를 창안한 것으로, 이를 첨부한 도면을 참조하여 상세히 설명하면 다음과 같다.In view of these problems, the present invention detects the high frequency envelope signal of VPC and compares it with the reference voltage when the VRC is in the mode of performing the recording edit function (Syncro Edit) at the time of the reproduction or no signal without connecting a separate cable. After the setting value, the recording stop state is set. If the setting value is over, the recording function is performed. If the recording editing function is in reverse play mode, the system of recording and editing of Twin System V-Cal which records the desired part is created. This will be described in detail with reference to the accompanying drawings.

제4도는 본 발명 브이씨알의 트윈시스템 녹화편집수행장치의 블럭도로서 이에 도시한 바와같이, 펄스를 발생시키는 펄스발생부(12)와, 이 펄스발생부(12)의 출력에 따라 브이씨피(VCP)의 고주파 포락신호를 고주파 포락신호검출부(11-1)로 검출하여 위상변조(Phase Modulation)하고 시분할 처리방식에 의한 주기별로 일정전압을 출력하는 위상변조부(11)와, 이 위상변조부(11)의 출력을 스위칭주기 별로 1필드(field) 지연시키는 라인지연부(13)와, 이 라인지연부(13)의 출력을 매 필드별로 기준전압과 비교하여 검파하는 검출신호부(14)와, 상기 위상변조부(11)와 신호검출부(14)의 출력을 비교하는 비교기(15)와, 이 비교기(15)의 출력과 녹화편집시작신호(SYE)를 논리조합하여 동작모드상태를 검출하는 모드검출부(18)와, 이 모드검출부(18)의 출력에 따라 브이씨알(VCR)의 동작상태를 판별하고 동작모드를 수행시키는 마이크로프로세서(16)와, 이 마이크로프로세서(16)의 제어에 따라 변속재생 및 녹화를 수행하는 서보제어부(17)로 구성한 것으로, 매스터측은 브이씨피(VCP)이지만 슬래브측인 브이씨알(VCR)의 마이크로프로세서에 별도의 포트가 필요없이 브이씨피(VCP)에서 매 필드당 출력하는 고주파 포락신호를 검출하여 녹화편집기능을 수행하므로 브이씨알이 매스터-슬래브기능을 겸하게 된다.4 is a block diagram of a twin system recording and editing apparatus of the present invention. As shown in FIG. 4, a pulse generator 12 for generating a pulse and a VPC according to the output of the pulse generator 12 are shown.

And a comparator 15 for comparing the outputs of the phase modulator 11 and the signal detector 14, and the output of the comparator 15 and the recording edit start signal SYE in a logical combination to detect an operation mode state. The mode detection unit 18 and the VCR according to the output of the mode detection unit 18 It consists of a microprocessor 16 which determines a state and performs an operation mode, and a servo controller 17 which performs shift playback and recording under the control of the microprocessor 16.

상기 모드검출부(18)는 앤드게이트로 구성한다.The mode detector 18 is composed of an AND gate.

이와같이 구성한 본 발명 브이씨알의 트윈시스템 녹화편집수행방법 및 그 장치의 작용 및 효과를 제5도 녹화편집수행시 신호 흐름도, 제6도 녹화편집에 따른 각부의 신호파형도, 제7도 녹화편집시 테이프의 상태도를 참조하여 상세히 설명하면 다음과 같다.FIG. 5 is a flowchart illustrating the operation of the twin system recording and editing system of the present invention and the operation and effects of the apparatus according to the present invention. FIG. 6 is a signal flow chart when performing recording editing, and FIG. Referring to the state diagram of the tape in detail as follows.

먼저, 리모콘(R/C)으로 브이씨피(VCP)를 재생모드(Play)로 하고 브이씨알(VCR)을 녹화모드(REC)로 하여 녹화편집을 수행하면 상기 브이씨피(VCP)는 제6도 (a)에 도시한 바와같이 정속재생을 수행하여 위상변조부(11)는 제6도 (b)에 도시한 바와같은 상기 브이씨피(VCP)의 재생고주파신호(R.F)를 시분할 처리에 따른 주기별로 이상 변조하고 고주파포락신호검출부(11-1)는 제6도 (c)에 도시한 바와같은 펄스발생부(12)의 출력(HD)에 따라 제6도 (d)에 도시한 바와같은 일정치의 고주파포락신호(R.F.ENV)를 검출하여 출력한다.First, when VVC is set to play mode (Play) and VCR is set to record mode (REC) with the remote controller R / C, the VCP is shown in FIG. As shown in (a), the constant speed regeneration is performed so that the phase modulator 11 performs a period according to time division processing of the reproduction high frequency signal RF of the VCP as shown in FIG. The high frequency envelope signal detection unit 11-1 performs the same operation as shown in FIG. 6D according to the output HD of the pulse generator 12 as shown in FIG. 6C. The high frequency envelope signal RFENV is detected and output.

이때, 라인지연부(13)는 위상변조부(11)의 출력(R.F.ENV)을 입력받아 1필드(field) 지연시키고 검출신호부(14)는 상기 라인지연부(13)의 출력을 레벨이 큰 기준전압(Vref1)과 비교하여 재생고주파신호(R.F)의 변동이 커서 큐/리뷰(CUE/REV)의 연속인지 감지한 후 래치시키며 상기 위상변조부(11)의 출력(R.F.ENV)과 검출신호부(14)의 출력을 입력받은 비교기(15)는 레벨이 작은 기준전압(Vref1)과 비교하여 재생모드(Play)의 무신호나 변속모드의 레벨차가 큰 고주파포락신호(R.F.ENV)를 점검한다.At this time, the line delay unit 13 receives the output RFENV of the phase modulator 11 and delays one field, and the detection signal unit 14 sets the output of the line delay unit 13 to a large level. Compared to the reference voltage Vref 1 , the variation of the reproduction high frequency signal RF is large, and thus detecting whether it is a continuous queue / review (CUE / REV) and latching the latch. The comparator 15 receiving the output of the unit 14 checks the high frequency envelope signal RFENV having a large level difference between the non-signal of the play mode and the shift mode compared with the reference voltage Vref 1 having a small level. .

따라서, 비교기(15)의 출력이 입력된 모드검출부(18)에 리모콘(R/C)에서 저전위인 녹화편집시작신호(SYE)가 입력되어 제6도 (h)에 도시한 바와같이 저전위를 출력하면 마이크로프로세서(16)는 제6도 (i)에 도시한 바와같이 고전위의 녹화제어신호(REC-Ctl)를 서보제어부(17)에 출력하여 브이씨피(VCP)의 재생화면을 비디오테이프에 녹화한다.Accordingly, the low-potential recording edit start signal SYE is inputted to the mode detecting unit 18 to which the output of the comparator 15 is input, thereby lowering the low potential as shown in FIG. When outputting, the microprocessor 16 outputs the high-potential recording control signal REC-Ctl to the servo controller 17 as shown in FIG. 6 (i) to display the playback screen of the VCP. Record on.

한편, 브이씨알(VCR)에서 브이씨피(VCP)의 재생고주파신호(R.F)를 녹화편집함에 있어 스킵(Skip)할 화면에서 사용자가 상기 브이씨피(VCP)를 제6도 (e)에 도시한 바와같이 변속재생모드(CUE/REV)로 절환하면 위상변조부(11)는 제6도 (f)에 도시한 바와같은 재생고주파신호(R.F)를 입력받아 위상변조하여 제6도 (c)에 도시한 바와같은 펄스발생부(12)의 출력(HD)에 따라 제6도 (g)에 도시한 바와같이 레벨 변동이 큰 고주파포락신호(R.F.ENV)를 출력한다.On the other hand, in the recording and editing of the reproduction high frequency signal (RF) of the VCP (VCP) in the VCR (VCR), the user has shown the VCP (VCP) in FIG. As shown in FIG. 6C, the phase modulator 11 receives the reproduction high frequency signal RF as shown in FIG. 6 (f) and phase modulates it to FIG. According to the output HD of the pulse generator 12 as shown in FIG. 6, a high frequency envelope signal RFENV having a large level change is output as shown in FIG.

이때, 위상변조부(11)의 출력(R.F.ENV)이 입력된 라인지연부(13)의 1필드지연신호를 입력받은 검출신호부(14)는 재생고주파신호(R.F)의 큰 레벨변동을 감지하여 변속재생(CUE/REV)의 연속임을 감지하고, 상기 위상변조부(11)와 검출신호부(14)의 출력을 입력받은 비교기(15)는 기준전압(Vref2)과 비교하여 일정치(k) 이상이면 고전위를 모드검출부(18)에 출력하며 이에따라, 리모콘(R/C)의 고전위인 녹화편집시작신호(SYE)와 앤드게이트(AN11)에서 논리조합되어 제6도 (g)에 도시한 바와같은 고전위를 마이크로프로세서(16)에 출력한다.At this time, the detection signal unit 14 receiving the one field delay signal of the line delay unit 13 to which the output RFENV of the phase modulator 11 is input detects a large level change of the reproduction high frequency signal RF. The comparator 15 which detects that the shift reproduction (CUE / REV) is continuous and receives the output of the phase modulator 11 and the detection signal unit 14 is compared with the reference voltage Vref 2 to obtain a constant value k. ) or more if yiettara outputs a high potential to the mode detecting unit 18, the remote control (R / C), the start of the classical great record edit signal (in combination logic in SYE) and the aND gate (aN 11), Figure 6 (g) The high potential as shown is output to the microprocessor 16.

따라서, 마이크로프로세서(16)는 제6도 (h)에 도시한 바와같은 고전위의 녹화중지신호(REC-PAUSE)를 서보제어부(17)에 출력하여 브이씨알(VCR)의 녹화동작을 중지시키고 브이씨피(VCP)의 변속재생을 계속하면서 비교기(15)의 출력이 일정치(k) 이하인지 점검한다.Accordingly, the microprocessor 16 outputs the high potential recording stop signal REC-PAUSE as shown in FIG. 6 (h) to the servo controller 17 to stop the recording operation of the VCR. The shift reproduction of the VCP is continued and it is checked whether the output of the comparator 15 is equal to or less than a predetermined value k.

이때, 스킵(skip) 화면이 끝나 브이씨피(VCP)를 정속재생시켜 비교기(15)의 출력값이 일정치(k) 이하가 되어 모드검출부(18)에서 저전위가 출력하면 마이크로프로세서(16)는 서보제어부(17)를 제어하여 브이씨알(VCR)을 녹화모드(REC)로 하여 브이씨피(VCP)의 재생화면을 녹화한다.At this time, when the skip screen ends and the VCP is continuously played at a constant speed, and the output value of the comparator 15 is equal to or less than a predetermined value k, and the low potential is output from the mode detector 18, the microprocessor 16 The servo control unit 17 is controlled to record the playback screen of the VCP in the recording mode REC.

또한, 브이씨피(VCP)의 재생화면없는 무신호 구간에서도 변속재생모드(CUE/REV)의 경우와 동일한 동작을 수행하여 키 절환없이 브이씨알(VCR)을 녹화중지 상태로 하며, 사용자가 제7도 (a)에 도시한 바와 같은 화면(A)을 스킵(Skip)하였을 경우 리뷰(REVIEW)하면서 스킵(Skip)한 화면을 찾아 브이씨피(VCP)를 재생모드(Play)로 한 후 브이씨알(VCR)에서 제7도 (b)에 도시한 바와같이 녹화편집을 수행하고, 브이씨피(VCP)의 역재생의 경우에도 설정된 기준값을 판별한 마이크로프로세서(16)의 제어를 받는 서보제어부(17)를 통해 녹화편집이 가능하다.In addition, the same operation as in the case of the variable speed playback mode (CUE / REV) is performed even in the no-signal section without the playback screen of the VCP, so that the VCR is stopped without changing the key. In the case of skipping screen A as shown in FIG. (A), the screen is skipped while being reviewed, and the VCP is set to the playback mode.
