본 발명은 8mm VCR에 관한 것으로, 특히 PCM(Pulse Code Modulation) 기능이 없는 경우 테이프에서 사용하지 않는 부기록 영역(PUM 신호와 트래킹파이롯트 신호를 기록하는 부분)에 수평으로 고정헤드를 추가로 부착시켜 상기된 부기록영역을 사용가능 토록함으로서 오디오 편집기능 및 캡션(Caption) 기능을 수행할 수 있도록 하는 8mm VCR의 오디오 편집장치에 관한 것이다.The present invention relates to an 8mm VCR. In particular, when the PCM (Pulse Code Modulation) function is not provided, an additional fixed head is horizontally attached to an unused sub-recording area (a portion for recording PUM signal and tracking pilot signal). The present invention relates to an audio editing apparatus of an 8mm VCR which enables the audio recording function and the caption function to be made available.

현재 가정용 VCR의 주류를 이루고 있는 1/2인치 VCR은 테이프에 별도의 오디오 트랙을 갖추고 있어서 간단하게 오디오 더빙 및 오디오 편집을 수행할 수 있었다.The 1 / 2-inch VCR, now the mainstream of home VCRs, has a separate audio track on the tape, making it easy to dub audio and edit audio.

그러나, 8mm VCR의 경우에는 별도의 오디오 트랙이 없으며 오디오신호를 비데오 신호와 함께 FM 변조시켜 부기록영역을 제외한 주기록영역(비데오 신호와 FM 오디오신호 및 트래킹파롯트신호를 기록하는 부분)에 기록하게 되므로서 오디오 편집을 수행할 수 없었다.However, in case of 8mm VCR, there is no separate audio track, and the audio signal is FM-modulated together with the video signal and recorded in the main recording area (the part which records the video signal, the FM audio signal and the tracking lot signal) except the sub recording area. As a result, audio editing could not be performed.

다만, PCM 기능을 추가하여 부기록영역을 사용하므로서 오디오 편집을 수행할 수 있었다.However, by adding the PCM function, audio editing can be performed by using the sub-recording area.

그러나, PCM 기능을 적용시킬 경우 가격이 상승하게 되므로 일부 고급 기종을 제외하고는 PCM 기능을 적용시키지 않고 있다.However, since the price increases when the PCM function is applied, the PCM function is not applied except for some high-end models.

따라서, 8mm VCR의 대부분을 차지하고 있는 PCM 기능이 없는 저가형 모델에서는 오디오 편집을 수행할 수 없는 문제점이 있었다.Therefore, there is a problem that audio editing cannot be performed in the low-cost model without the PCM function, which occupies most of the 8mm VCR.

이에 따라, 본 발명의 첫번째 목적은 PCM 기능이 없는 8mm VCR에서 사용하지 않는 부기록영역에 수평으로 2개의 고정헤드를 추가로 설치하여 부기록영역을 사용할 수 있도록 함으로서 오디오 편집이 가능하도록 한 것이다.Accordingly, the first object of the present invention is to enable audio editing by additionally installing two fixed heads horizontally in a sub recording area not used in an 8 mm VCR without a PCM function so as to use the sub recording area.

또다른 목적은 부기록영역에 수평으로 2개의 고정헤드를 설치하여 2개의 트랙을 확보한후, 하나의 트랙은 오디오용으로 사용하고, 다른 하나는 캡션 및 오디오 겸용으로 사용하여 캡션 기능도 수행할 수 있도록 한것이다.Another purpose is to secure two tracks by installing two fixed heads horizontally in the sub-recording area, one track for audio, and the other for caption and audio. It is to be possible.

상기한 목적을 달성하기 위한 본 발명은 리니어 오디오신호와 캡션 데이타를 부기록영역에 기록 및 재생하고 콘트롤신호를 고정헤드트랙에 기록 및 재생하는 고정헤드와, 상기 고정헤드로부터 재생되는 캡션데이타를 처리하는 캡션데이타 처리수단과, 상기 고정헤드와 FM 오디오 앰프에서 출력되는 오디오신호를 처리하는 오디오신호 처리수단과, 상기 캡션데이타 처리수단 또는 오디오신호 처리수단을 선택하여 고정헤드에 연결하여 주는 선택수단과, FM 오디오 앰프와 상기 오디오신호 처리수단의 연결상태를 제어하는 스위칭수단과, 상기 선택수단과 스위칭수단을 제어하며 상기 캡션데이타 처리수단에서 처리된 캡션데이타에 의한 문자신호를 OSD 수단에 출력하고 상기 콘트롤헤드에서 기록 또는 재생되는 콘트롤 신호를 처리하는 마이크로 프로세서로 구성되어 오디오 편집은 물론 캡션 기능도 수행할 수 있도록 한 것으로써 이하 첨부도면에 의거 상세히 설명한다.The present invention for achieving the above object is a fixed head for recording and reproducing the linear audio signal and caption data in the sub-recording area and recording and reproducing the control signal to the fixed head track, and processing caption data reproduced from the fixed head. Caption data processing means, audio signal processing means for processing audio signals output from the fixed head and the FM audio amplifier, selection means for selecting the caption data processing means or audio signal processing means and connecting the fixed head; Switching means for controlling a connection state between the FM audio amplifier and the audio signal processing means, controlling the selection means and the switching means, and outputting a text signal by caption data processed by the caption data processing means to the OSD means; Micro Pro handles control signals recorded or played back on the control head It comprises with each other, as well as audio editing captioning can also be described in detail based on the accompanying drawings as to write to be performed.

제1도는 일반적인 8mm VCR에서 신호가 기록되는 테이프의 경사트랙의 패턴을 보인 개략도이다.1 is a schematic diagram showing a pattern of an inclined track of a tape on which a signal is recorded in a typical 8 mm VCR.

제1도에서 알 수 있듯이, 8mm 테이프(100)의 양측에는 0.6(mm)의 고정헤드용트랙(101a,101b)이 형성되어 있다.As can be seen in FIG. 1, fixed head tracks 101a and 101b of 0.6 mm are formed on both sides of the 8 mm tape 100.

상기 고정헤드용트랙(101a,101b)의 내측으로는 0.1(mm)의 가드밴드(102a,102b)가 형성되어 있다.Inside the fixed head tracks 101a and 101b, 0.1 (mm) guard bands 102a and 102b are formed.

상기 가드밴드(102a,102b)의 내측으로는 주기록영역과 부기록영역으로 이루어진 기록영역(103)이 형성되어 있다. 상기 기록영역(103)의 주기록영역에는 비데오 신호와 FM 오디오신호 및 트래킹파이롯트신호가 기록되고, 부기록영역에는 PCM 신호와 트래킹파이롯트 신호가 기록된다.Inside the guard bands 102a and 102b, a recording area 103 consisting of a main recording area and a sub recording area is formed. The video signal, the FM audio signal, and the tracking pilot signal are recorded in the main recording area of the recording area 103, and the PCM signal and the tracking pilot signal are recorded in the sub recording area.

상기 기록영역(103)에서 주부기록영역은 각각 테이프(100)가 X축으로 이동할때 헤드(도시하지 않음)가 Y축으로 180°와 36°회전하므로서 이루어지는 경사트랙 부분이다.In the recording area 103, the housewife recording area is an inclined track portion formed by rotating the head (not shown) 180 degrees and 36 degrees along the Y axis when the tape 100 moves on the X axis.

따라서, PCM 기능을 갖춘 8mm VCR은 PCM 신호와 트랙킹파이롯트 신호를 기록하는 부기록영역에 PCM 오디오신호를 기록시켜 오디오 편집을 수행할 수가 있었다.Therefore, the 8mm VCR equipped with the PCM function could perform audio editing by recording the PCM audio signal in the sub-recording area for recording the PCM signal and the tracking pilot signal.

그러나, 현재 대부분의 8mm VCR은 PCM 기능을 갖추지 않은 보급형이다.However, most 8mm VCRs are currently low cost without PCM capability.

PCM기능을 갖추지 않은 8mm VCR은 테이프(100)에서 부기록 영역을 사용하지 못하여 오디오 편집을 수행할 수 없었다.The 8mm VCR without the PCM function could not use the sub-recording area on the tape 100 to perform audio editing.

본 발명은 상기 부기록영역에 2개의 고정헤드를 설치하여 2개의 채널을 확보함으로서 오디오신호를 기록 및 재생할 수 있도록 하여 오디오 편집은 물론 캡션기능도 수행할 수 있도록 한 것이다.According to the present invention, two fixed heads are provided in the sub-recording area so that two channels can be secured so that audio signals can be recorded and reproduced to perform audio editing as well as a caption function.

제2도는 본 발명에 다른 8mm VCR의 오디오 편집장치 블럭도이다.2 is a block diagram of an audio editing apparatus of an 8mm VCR according to the present invention.

제2도에서, 200은 리니어 오디오신호 또는 리니어 오디오신호와 캡션 데이타를 제1도의 부기록영역에 2채널로 기록하고 재생하는 제 1,2헤드(201,202)와 콘트롤 신호를 고정헤드용트랙(101b)에 기록하거나 재생하는 콘트롤헤드(203)로 구성된 고정헤드이다.In FIG. 2, 200 denotes first and second heads 201 and 202 and control signals for recording and reproducing a linear audio signal or a linear audio signal and caption data in two channels in the sub-recording area of FIG. Is a fixed head composed of a control head 203 for recording or reproducing.

상기 고정헤드(200)중 제1헤드(201)는 캡션데이타와 오디오신호를 기록하고 재생할 수 있는 캡션/오디오 겸용헤드이다.The first head 201 of the fixed head 200 is a caption / audio combined head capable of recording and reproducing caption data and audio signals.

210은 상기 제1헤드(201)로 부터 재생되는 캡션데이타를 처리하는 캡션데이타 처리수단이다.210 denotes caption data processing means for processing caption data reproduced from the first head 201.

220은 상기 고정헤드(200)와 기존의 FM 오디오 앰프(241)에서 출력되는 오디오신호를 처리하는 오디오 신호 처리수단이다.220 is an audio signal processing means for processing the audio signal output from the fixed head 200 and the existing FM audio amplifier 241.

230은 상기 캡신데이타 처리수단(210) 또는 오디오신호 처리수단(20)을 선택하여 상기 고정헤드(200)의 제1헤드(201)에 연결하여주는 선택수단이다.230 is a selection means for selecting the capsine data processing means 210 or the audio signal processing means 20 and connecting it to the first head 201 of the fixed head 200.

상기 선택수단(230)의 선택에 의하여 제1헤드(201)는 캡션데이타를 기록하고 재생하거나, 또는 오디오신호를 기록하고 재생하게 된다.By the selection of the selection means 230, the first head 201 records and reproduces caption data, or records and reproduces audio signals.

240은 상기 FM 오디오 앰프(241)와 오디오신호 처리수단(220)의 연결상태를 제어하는 스위칭수단이다.240 is a switching means for controlling the connection state of the FM audio amplifier 241 and the audio signal processing means 220.

상기 스위칭수단(240)의 스위칭에 의하여 상기 오디오신호 처리수단(220)은 상기 FM 오디오 앰프(241)에서 출력되는 FM 오디오신호를 처리하거나, 상기 고정헤드(200)에서 기록 또는 재생되는 오디오신호를 처리하게 된다.By the switching of the switching means 240, the audio signal processing means 220 processes the FM audio signal output from the FM audio amplifier 241 or the audio signal recorded or reproduced by the fixed head 200. Will be processed.

250은 선택수단(230)과 스위칭수단(240)을 제어하며, 캡션 데이타 처리수단(210)에서 처리된 캡션데이타에 의한 문자신호를 OSD 수단(251)에 출력하고, 콘트롤 헤드(203)에서 기록 또는 재생되는 콘트롤신호를 처리하는 마이크로프로세서이다.250 controls the selecting means 230 and the switching means 240, and outputs the text signal by the caption data processed by the caption data processing means 210 to the OSD means 251, and records in the control head 203. Or a microprocessor for processing a control signal to be reproduced.

따라서, 8mm VCR의 기본 기능은 FM 오디오신호를 재생시킬 경우 마이크로 프로세서(250)는 제어신호(S2)를 출력하여 스위칭 수단(240)을 온시킨다.Therefore, the basic function of the 8mm VCR is to reproduce the FM audio signal, the microprocessor 250 outputs the control signal (S2) to turn on the switching means 240.

이때, FM 오디오 앰프(241)는 비디오 신호와 FM 오디오신호 및 트래킹파이롯트 신호가 기록되어 있는 8mm 테이프(100)의 주기록영역에서 재생되는 FM 오디오신호를 출력한다.At this time, the FM audio amplifier 241 outputs the FM audio signal reproduced in the main recording area of the 8 mm tape 100 in which the video signal, the FM audio signal, and the tracking pilot signal are recorded.

FM 오디오 앰프(241)에서 출력되는 FM 오디오신호는 스위칭수단(240)을 통하여 오디오신호 처리수단(220)에 입력된다.The FM audio signal output from the FM audio amplifier 241 is input to the audio signal processing means 220 through the switching means 240.

오디오신호 처리수단(220)은 입력된 FM 오디오신호를 처리하여 스피커와 같은 출력수단을 통하여 출력한다.The audio signal processing unit 220 processes the input FM audio signal and outputs the same through an output unit such as a speaker.

그러므로, 사용자는 비데오와 FM 오디오를 시청할 수 있게 된다.Thus, the user can watch video and FM audio.

한편, 제1도에서 기록영역(103)중 부기록영역을 2채널의 오디오신호용으로 사용하고자하면, 마이크로프로세서(250)는 제어신호(S1)(S2)를 출력하여 선택수단(230)의 공통단자(C)와 선택단자(NC)가 접속되도록 하고, 스위칭수단(240)은 오프되도륵 하여 오디오신호 처리수단(220)과 FM 오디오 앰프(241)의 연결을 차단하게 된다.On the other hand, in FIG. 1, if the sub recording area of the recording area 103 is to be used for two channels of audio signals, the microprocessor 250 outputs control signals S1 and S2 so that the selection means 230 is common. The terminal C and the selection terminal NC are connected to each other, and the switching unit 240 is turned off to cut off the connection between the audio signal processing unit 220 and the FM audio amplifier 241.

상기 선택수단(230)의 공통단자(C)와 선택단자(NC)가 접속되고 스위칭수단(240)이 오프되면, 부기록영역의 2채널에 기록된 리니어 오디오신호는 고정헤드(200)의 제1,2헤드(201,202)에 의하여 재생되어 오디오 신호 처리수단(220)에 인가된다.When the common terminal C of the selecting means 230 and the selecting terminal NC are connected and the switching means 240 is turned off, the linear audio signal recorded in the two channels of the sub-recording area is stored in the fixed head 200. It is reproduced by the first and second heads 201 and 202 and applied to the audio signal processing means 220.

상기 오디오신호 처리수단(220)은 제1,2헤드(201,202)에 의해 재생된 오디오신호를 처리하여 출력하게 된다.The audio signal processing unit 220 processes and outputs an audio signal reproduced by the first and second heads 201 and 202.

이와같이, 2개의 헤드(201,202)를 사용하면 스테레오도 가능하며, 부기록영역에 확보된 2채널중 하나의 채널에는 영어를 기록하고 다른 채널에는 일어를 기록하면 사용자는 원하는 언어를 선택하여 청취할 수도 있다.As such, when two heads 201 and 202 are used, stereo is possible, and if one of two channels secured in the sub-recording area is recorded in English and the other channel is recorded in Japanese, the user may select and listen to a desired language. have.

또한, 제1도의 부기록영역의 한 채널은 캡션용으로 사용하고, 다른 한채널은 오디오신호용으로 사용하고자하면, 마이크로 프로세서(250)는 제어신호(S1)를 출력하여 선택수단(230)의 공통단자(C)와 선택단자(NO)를 접속시킨다.In addition, if one channel of the sub-recording area of FIG. 1 is to be used for the caption and the other channel is to be used for the audio signal, the microprocessor 250 outputs the control signal S1 to common to the selection means 230. The terminal C and the selection terminal NO are connected.

선택수단(230)의 공통단자(C)와 선택단자(NO)가 접속되면, 부기록영역의 2채널중 한채널에 기록된 캡션 데이타는 고정헤드(200)의 제1헤드(201)에 의하여 재생되어 캡션데이타 처리수단(210)에 인가된다.When the common terminal C of the selecting means 230 and the selecting terminal NO are connected, caption data recorded in one of two channels of the sub-recording area is transferred by the first head 201 of the fixed head 200. It is reproduced and applied to the caption data processing means 210.

캡션데이타 처리수단(210)에서는 재생된 신호를 처리하여 캡션데이타를 마이크로프로세서(250)에 인가한다.The caption data processing means 210 processes the reproduced signal and applies the caption data to the microprocessor 250.

마이크로프로세서(250)는 상기 캡션데이타처리수단(210)에서 처리된 캡션데이타에 따른 문자신호를 OSD수단(251)에 인가하여 캡션 자막을 발생한다.The microprocessor 250 generates a caption caption by applying a text signal corresponding to the caption data processed by the caption data processing means 210 to the OSD means 251.

이때, 마이크로프로세서(25)는 제어신호(S2)를 출력하여 스위칭수단(240)을 온 또는 오프시킨다.At this time, the microprocessor 25 outputs a control signal S2 to turn on or off the switching means 240.

제어신호(S2)에 의해 상기 스위칭수단(240)이 온 되면, FM 오디오 앰프(241)의 출력과 고정헤드(200)의 제2헤드(202)에 의해 재생된 리니어 오디오신호는 오디오신호 처리수단(220)에 인가된다.When the switching means 240 is turned on by the control signal S2, the output of the FM audio amplifier 241 and the linear audio signal reproduced by the second head 202 of the fixed head 200 are audio signal processing means. Is applied to 220.

따라서, 상기 오디오신호 처리수단(220)은 주기록영역에 기록되었던 FM 오디오신호와 부기록영역에 기록되었던 리니어 오디오신호를 처리하여 출력하게 된다.Accordingly, the audio signal processing unit 220 processes and outputs the FM audio signal recorded in the main recording area and the linear audio signal recorded in the sub recording area.

여기서, 제어신호(S1,S2)는 콘트롤헤드(203)로 부터 읽혀지는 제어신호(S3)에 따라서 마이크로프로세서(250)에서 출력되도록 하여도 된다.Here, the control signals S1 and S2 may be output from the microprocessor 250 in accordance with the control signal S3 read from the control head 203.

즉, 테이프에 비데오신호와 오디오신호등을 기록할때, 테이프의 고정헤드용트랙에 사용자가 임의로 제어신호(S3)를 기록하여 두면, 재생시 콘트롤 헤드(203)에 의해 제어신호(S3)가 리드되고, 리드되는 제어신호(S3)는 마이크로프로세서(250)에 인가된다.That is, when recording a video signal and an audio signal on the tape, if the user arbitrarily records the control signal S3 on the fixed head track of the tape, the control signal S3 is read by the control head 203 during playback. The control signal S3 to be read is applied to the microprocessor 250.

제어신호(S3)가 마이크로프로세서(250)에 인가되면, 마이크로프로세서(250)는 제어신호(S3)에 따라 제어신호(S1,S2)를 출력하여 선택수단(230)과 스위칭수단(240)를 제어한다.When the control signal S3 is applied to the microprocessor 250, the microprocessor 250 outputs the control signals S1 and S2 according to the control signal S3 to select the selecting means 230 and the switching means 240. To control.

이때, 미리 기록하는 제어신호(S3)는 사용자가 편집을 하고자 하는 순서에 의하거나, 원하는 부분을 자동적으로 절환하며 듣고자 하는 순서에 의거하여 임의로 기록하게 된다.At this time, the control signal S3 to be recorded in advance is arbitrarily recorded in accordance with the order in which the user wants to edit or in accordance with the order in which the user wants to switch automatically.

여기서, 리니어 오디오신호는 PCM 신호보다 저주파로 심층기록되고 또한 기록각도가 다르므로 PCM 신호가 기록되어 있는 8mm 테이프의 부기록영역에 리니어 오디오신호를 기록하여도 PCM 신호와 리니어 오디오신호간의 크로스 토크현상이 발생하지 않게 된다.Here, since the linear audio signal is recorded deeper at a lower frequency than the PCM signal and the recording angle is different, the crosstalk between the PCM signal and the linear audio signal is recorded even when the linear audio signal is recorded in the sub-recording area of the 8mm tape in which the PCM signal is recorded. This will not happen.

그러면, 재생기 콘트롤헤드(203)에 의해 재생되는 하이레벨의 콘트롤신호(S3)를 마이크로프로세서(250)가 인식하게 되고, 마이크로프로세서(250)는 제어신호(S2)를 출력하여 스위칭수단(240)을 오프시킨다.Then, the microprocessor 250 recognizes the high-level control signal S3 reproduced by the player control head 203, and the microprocessor 250 outputs the control signal S2 to switch means 240. Off.

스위칭수단(240)이 오프되면, 부기록영역에 편집되어 기록되었던 리니어 오디오신호는 선택수단(230)을 통하여 오디오신호 처리수단(220)에 인가되어 처리된다.When the switching means 240 is turned off, the linear audio signal that has been edited and recorded in the sub recording area is applied to the audio signal processing means 220 through the selection means 230 and processed.

제4d도는 오디오신호 처리수단(220)에서 처리되어 최종적으로 출력되는 오디오신호의 일예도이다.4d is an example of an audio signal processed by the audio signal processing unit 220 and finally output.

최종적으로 출력되는 오디오신호는, 제4a도에 도시된 바와같은 콘트롤신호(S3)가 로우레벨이면 스위칭수단(240)이 온되어 주기록영역에 기록되어 있는 FM 오디오신호가 오디오신호 처리수단(220)에 인가되고, 콘트롤신호(S3)가 하이레벨이면 스위칭 수단(240)이 오프되어 FM 오디오신호의 출력이 차단된다.Finally, if the control signal S3 as shown in FIG. 4A is at a low level, the audio signal to be finally output is switched to the switching means 240, and the FM audio signal recorded in the main recording area is converted into the audio signal processing means 220. If the control signal (S3) is at a high level, the switching means 240 is turned off to block the output of the FM audio signal.

따라서, 콘트롤 신호(S3)가 로우레벨이면 제4c도에 도시된 바와 같이 리니어 오디오신호는 기록되어 있지 않으므로 오디오신호 처리수단(220)에서는 FM 오디오신호를 처리하여 출력하고, 콘트롤신호(S3)가 하이레벨이면 제4c도에 도시된 바와같이 편집된 리니어 오디오신호를 처리하여 최종적으로 출력하게 된다.Therefore, if the control signal S3 is at the low level, as shown in FIG. 4C, since the linear audio signal is not recorded, the audio signal processing means 220 processes and outputs the FM audio signal, and the control signal S3 is At the high level, the edited linear audio signal is processed and finally output as shown in FIG. 4C.
