본 발명은 브이씨알 테이프의 음성신호를 편집하는 기술에 관한 것으로, 특히 브이씨알 테이프에 기록되어 있는 영상신호와 음성신호를 재생하면서 그 음성신호만을 직접 편집할 수 있는 티브이/브이씨알 복합시스템의 음성편집장치에 관한 것이다.The present invention relates to a technique for editing an audio signal of a VRC tape, and more particularly, to reproduce a video signal and an audio signal recorded on a VRC tape, and to directly edit only the audio signal. It is about an editing apparatus.

종래의 티브이/브이씨알 복합시스템은, 제1도에 도시된 바와 같이, 제1스위치제어신호(S1)와 녹화제어신호(S3)를 출력하는 마이크로 컴퓨터(100)와, 상기 마이크로 컴퓨터(100)의 제1스위치제어신호(S1)에 따라 외부음성입력부(101)의 (외부음성신호)와 음성중간주파수(102)의 티브이음성신호중 어느 하나를 선택하는 제1스위치(SW)와, 상기 제1스위치(SW1)가 선택한 외부음성신호 또는 티브이음성신호에 대해 소정 의 음성처리를 하는 음성처리부(103)와, 상기 음성처리부(103)가 음성처리한 외부음성신호 또는 티브이음성신호를 일정레벨로 증폭하여 스피커(107)로 출력하는 음성증폭부(104)와, 상기 마이크로 컴퓨터(100)의 녹화제어신호(S3)에 의해 구동되어 중첩부(110)를 통해 상기 음성처리부(103)가 음성처리한 외부음성신호 또는 티브이음성신호에 소정주파수의 바이어스를 걸어 음성녹화헤드(106)로 보내는 음성녹화바이어스(105)로 구성된다.In the conventional TV / BT composite system, as shown in FIG. 1, a microcomputer 100 for outputting a first switch control signal S1 and a recording control signal S3, and the microcomputer 100 A first switch SW for selecting any one of an external voice signal of the external voice input unit 101 and a TV voice signal of the voice intermediate frequency 102 according to the first switch control signal S1 of FIG. Amplifying the external audio signal or the TV audio signal that the voice processing unit 103 performs predetermined sound processing on the external audio signal or the TV audio signal selected by the switch SW1, and the voice processing unit 103 processes the audio to a predetermined level. Driven by the audio amplifier 104 outputted to the speaker 107 and the recording control signal S3 of the microcomputer 100 and processed by the audio processor 103 through the superimposed unit 110. Bar of predetermined frequency to external sound signal or TV sound signal The voice recording bias 105 is sent to the voice recording head 106 by hanging the ear.

이와 같은 구성을 가지고 종래에는, 먼저 외부음성입력부(101)의 외부음성신호 또는 음성중간주파부(102)의 티브이음성신호를 스피커(107)를 통해 출력할 때는, 마이크로 컴퓨터(100)에서 출력되는 제1스위치제어신호(S1)에 의한 제1스위치(SW1)의 스위칭작용에 따라 상기 외부음성입력부(101)의 외부 음성신호와 음성중간주파부(102)의 티브이음성신호중 어느 하나가 선택되어 그 선택된 외부음성신호 또는 티브이음성신호가 음성처리부(103)에서 소정의 처리과정을 거쳐 음성증폭부(104)에서 일정레벨 증폭되며 이 증폭된 외부음성신호 또는 티브이음성신호가 최종적으로 스피커(107)를 통해 출력되도록 되어 있다.With such a configuration, conventionally, when outputting the external voice signal of the external voice input unit 101 or the TV voice signal of the voice intermediate frequency unit 102 through the speaker 107, it is output from the microcomputer 100. According to the switching action of the first switch SW1 by the first switch control signal S1, one of the external voice signal of the external voice input unit 101 and the TV voice signal of the voice intermediate frequency unit 102 is selected and The selected external voice signal or TV sound signal is amplified by the voice amplifier 104 through a predetermined process in the voice processor 103, and the amplified external voice signal or TV sound signal is finally turned on the speaker 107. The output is through.

그리고, 이와 같이 스피커(107)를 통해 음성신호가 출력되면서 마이크로 컴퓨터(100)에서 출력된 녹화제어신호(S3)에 의해 음성녹화바이어스부(105)가 구동되어 음성처리부(103)에서 출력된 티브이음성신호 또는 외부음성신호에 중첩부(110)에서 70KHz의 바이어스가 걸려서 음성녹화헤드(106)를 통해 브이씨알 테이프(도시되지 않음)에 기록되도록 되어 있다.Then, as the audio signal is output through the speaker 107, the voice recording bias unit 105 is driven by the recording control signal S3 output from the microcomputer 100 to output the TV output from the voice processing unit 103. The audio signal or the external audio signal is biased at 70 KHz at the superimposition unit 110 so that it is recorded on the VRC tape (not shown) through the voice recording head 106.

그러나, 이때 사용자들은 브이씨알 테이프에 녹화되어 있는 음성신호 및 영상신호를 재생할 때 그 음성신호만을 편집하기를 원하지만, 종래의 티브이/브이씨알 복합시스템은 재생시 음성신호를 편집할 수 있는 기능을 갖추고 있지 않아 사용자가 욕구를 충족시켜 주기에는 미흡한 것이다.However, at this time, the user wants to edit only the audio signal when the audio signal and the video signal recorded on the VRC tape are reproduced, but the conventional TV / VCAL system has a function to edit the audio signal during playback. It is not enough to satisfy the needs of users.

이와 같이, 종래의 티브이/브이씨알 복합시스템은 사용자가 브이씨알 테이프의 재생시에 음성신호만을 편집하기를 원함에도 불구하고 재생시 음성신호를 편집할 수 있는 음성편집기능, 즉 더빙기능(dubbing function)을 갖추고 있지 않기 때문에, 사용자의 음성신호에 대한 편집욕구를 전혀 충족시켜줄 수 없다는 문제점을 갖추고 있었다.As described above, the conventional TV / VC composite system has a voice editing function, that is, a dubbing function, that allows the user to edit the voice signal at the time of playback even though the user wants to edit only the voice signal at the time of playing the VRC tape. Because it does not have a, it has a problem that it can not meet the user's desire to edit the voice signal at all.

따라서 본 발명은 이러한 종래의 문제점을 해결하기 위하여 티브이/브이씨알 복합시스템의 음성편집장치를 창안한 것이며, 브이씨알 테이프에 녹화되어 있는 음성신호 및 영상신호를 재생하면서 그 음성신호만을 자유로이 편집할 수 있게 하는 티브이/브이씨알 복합시스템의 음성편집장치를 제공하는 것을 목적으로 한다.Therefore, in order to solve the conventional problems, the present invention was devised a voice editing apparatus of a TV / VC composite system, and only the audio signal can be freely edited while reproducing the audio signal and the video signal recorded on the VRC tape.

이제, 상기와 같이 구성된 본 발명에 대하여 하나의 구체적 실시예를 나타낸 제2도 및 제3도를 참조하여 본 발명의 작용 및 효과를 상세히 설명한다.Now, the operation and effect of the present invention will be described in detail with reference to FIGS. 2 and 3 showing one specific embodiment of the present invention configured as described above.

먼저, 외부음성입력부(201)의 외부음성신호 또는 음성중간주파부(202)의 티브이음성신호를 스피커(207)를 통해 출력할 때는 마이크로컴퓨터(200)에서 출력되는 제2스위치제어신호(S2)에 의해 제2스위치(SW2)가 고정단자(b2)쪽으로 스위칭된 상태에서, 마이크로컴퓨터(200)의 제1스위치제어신호(S1)에 따른 제2스위치(SW1)의 스위칭작용에 따라 외부음성입력부(201)의 외부음성신호와 음성중간주파부(202)의 티브이음성신호중 어느 하나가 선택되어 음성처리부(203)에서 소정의 처리과정을 거친다음, 음성증폭부(204)에서 일정레벨로 증폭되어 스피커(207)로 출력된다.First, when outputting the external voice signal of the external voice input unit 201 or the TV voice signal of the voice intermediate frequency unit 202 through the speaker 207, the second switch control signal (S2) output from the microcomputer 200 In the state where the second switch SW2 is switched to the fixed terminal b2 by the external switch, the external voice input unit is switched according to the switching action of the second switch SW1 according to the first switch control signal S1 of the microcomputer 200. One of the external voice signal of the 201 and the TV voice signal of the voice intermediate frequency unit 202 is selected and subjected to a predetermined process by the voice processor 203, and then amplified to a predetermined level by the voice amplifier 204. It is output to the speaker 207.

즉, 제3도에 도표로 나타낸 바와 같이, 마이크로컴퓨터(200)의 제1스위치제어신호(S1)에 의해 제1스위치(SW1)가 고정단자(a1)쪽으로 스위칭되면 티브이음성신호가 스피커(207)로 출력될 것이고, 고정단자(a2)쪽으로 스위칭되면 외부음성신호가 스피커(207)로 출력될 것이다.That is, as shown in the diagram of FIG. 3, when the first switch SW1 is switched to the fixed terminal a1 by the first switch control signal S1 of the microcomputer 200, the TV audio signal is transmitted to the speaker 207. ) And the external voice signal is output to the speaker 207 when switched to the fixed terminal a2.

그리고, 상기와 같이 스피커(207)를 통해 외부음성입력부(201)의 외부음성신호 또는 음성중간주파부(202)의 티브이음성신호가 스피커(207)를 통해 출력되면서, 마이크로컴퓨터(200)에서 출력된 녹화제어신호(S3)에 의해 음성녹화바이어스부(205)가 구동되어 음성처리부(203)에서 출력된 티브이음성신호 또는 외부음성신호에 중첩부(210)에서 70KHz의 바이어스가 걸려서 음성녹화헤드(206)를 통해 브이씨알테이브(도시되지 않음)에 녹화된다.As described above, the external voice signal of the external voice input unit 201 or the TV voice signal of the voice intermediate frequency unit 202 is output through the speaker 207 through the speaker 207 and output from the microcomputer 200. The voice recording bias unit 205 is driven by the recorded control signal S3 and a 70KHz bias is applied to the TV voice signal or the external voice signal output from the voice processor 203 and the voice recording head 205 is pressed. Recorded to VRT tape (not shown) via 206.

한편, 영상신호 및 음성신호를 재생하면서 음성신호만을 편집하고자 할 때는, 마이크로컴퓨터(200)에서 출력되는 제2스위치제어신호(S2)에 의헤 제2스위치(SW2)가 고정단자(b1)쪽으로 스위칭되도록하면 되며, 그림으로써 외부음성입력부(201)의 외부음성신호 또는 음성중간주파부(202)의 티브이음성신호가 음성믹싱부(209)에서 외부마이크입력부(208)의 마이크신호와 믹싱되고 이 믹싱으로 얻어진 혼합음 성신호가 음성처리부(203)에 입력된다.On the other hand, when reproducing only the audio signal while reproducing the video signal and the audio signal, the second switch SW2 is switched to the fixed terminal b1 by the second switch control signal S2 output from the microcomputer 200. As an illustration, the external voice signal of the external voice input unit 201 or the TV voice signal of the voice intermediate frequency unit 202 is mixed with the microphone signal of the external microphone input unit 208 in the voice mixing unit 209 and mixed. The mixed speech signal thus obtained is input to the speech processing section 203.

이와같이 음성처리부(203)에 입력된 혼합음성신호는 그 음성처리부(203)에서 소정의 처리과정을 거쳐 음성증폭부(204)에서 일정레벨증폭되며 이렇게 증폭된 혼합음성신호가 스피커(207)를 통해 출력됨으로써, 외부음성신호 또는 티브이음성신호에 외부마이크입력부(208)의 마이크신호가 편집되는 결과가 되는 것이다.As such, the mixed voice signal input to the voice processor 203 is amplified by the voice amplifier 204 by a predetermined level through a predetermined process in the voice processor 203, and the mixed voice signal amplified in this manner is amplified by the speaker 207. By outputting, the microphone signal of the external microphone input unit 208 is edited into the external voice signal or the TV voice signal.

즉, 제3도에 나타낸 바와같이, 마이크로컴퓨터(200)의 제2스위치제어신호(S2)에 의해 제2스위치(SW2)가 고정단자(b1)쪽으로 스위칭된 상태에서, 마이크로컴퓨터(200)의 제1스위치제어신호(S1)에 의해 제1스위치(SW1)가 고정단자(a1)쪽으로 스위칭되면 외부음성신호에 마이크신호가 편집되며, 제1스위치제어신호(SW1)가 고정단자(a2)쪽으로 스위칭되되면 티브이음성신호에 마이크신호가 편집된다.That is, as shown in FIG. 3, in the state where the second switch SW2 is switched to the fixed terminal b1 by the second switch control signal S2 of the microcomputer 200, the microcomputer 200 When the first switch SW1 is switched to the fixed terminal a1 by the first switch control signal S1, the microphone signal is edited to the external audio signal, and the first switch control signal SW1 is directed to the fixed terminal a2. When switched, the microphone signal is edited into the TV audio signal.

한편, 마이크로컴퓨터(200)에서 제1스위치제어신호(S1)와 제2스위치제어신호(S2)가 출력될 때 동시에 녹화제어신호(S3)가 출력되므로 이 녹화제어신호(S3)에 의해 음성녹화바이어스부(205)가 구동되어 음성처리부(203)에서 출력된 혼합음 성신호에 중첩부(210)에서 70KHz의 바이어스가 걸려서 음성녹화헤드(206)를 통해 그 혼합음성신호가 브이씨알 테이프에 녹화된다.On the other hand, when the first switch control signal S1 and the second switch control signal S2 are output from the microcomputer 200, the recording control signal S3 is output at the same time, so that voice recording is performed by the recording control signal S3. The bias unit 205 is driven so that the mixed voice signal output from the voice processing unit 203 is biased at 70 KHz at the superposition unit 210, and the mixed voice signal is recorded on the VRC tape through the voice recording head 206. do.

이때, 영상신호는 재생모드이기 때문에 음성신호의 편집은 영상신호에 영향을 주지 않는다.At this time, since the video signal is in the playback mode, editing of the audio signal does not affect the video signal.

지금까지 설명한 바와같이, 본 발명은 외부마이크입력부와 음성믹싱부 및 제2스위치를 이용하여 종래의 티브이/브이씨알 복합시스템에 음성편집기능 즉 더빙기능을 추가함으로써, 브이씨알 테이프에 기록되어 있는 영상신호와 음성신호를 재생하면서 그 음성신호만을 편집할 수 있다는 효과를 갖는다.As described so far, the present invention adds a voice editing function, ie a dubbing function, to a conventional TV / VCAL system by using an external microphone input unit, a voice mixing unit, and a second switch, thereby recording an image recorded on a VRC tape. This has the effect that only the audio signal can be edited while reproducing the signal and the audio signal.
