본 고안은 음성다중방송의 우측챈널신호 및 좌측챈널신호에 식별신호를 함께 혼합하여 영상신호 기록재생장치의 테이프에 기록시킨후, 기록되어져 있는 신호를 영상신호기록재생장치로 재생하고자 할 경우에 어느 쪽의 신호가 재생되고 있는 가를 확인할 수 있도록 한 오디오 모우드의 자동확인회로에 관한 것이다.The present invention mixes the identification signal with the right channel signal and the left channel signal of audio multiplexing and records them on the tape of the video signal recording and reproducing apparatus, and then reproduces the recorded signals with the video signal recording and reproducing apparatus. It is about an automatic confirmation circuit of an audio mode for confirming whether a signal of a page is being reproduced.

일반적으로 음성다중방송을 영상신호기록재생장치로 테이프상에 기록하는 경우, 음성다중방송의 우측 및 좌측챈널신호는 혼합기에서 혼합되어 증폭기를 통해 증폭된 다음, 기록헤드에 의해서 테이프상에 기록된다.In general, when audio multicast is recorded on a tape by a video signal recording and reproducing apparatus, the right and left channel signals of the audio multicast are mixed in a mixer, amplified by an amplifier, and then recorded on a tape by a recording head.

테이프상에 기록된 신호를 재생하고자 할 경우에는 재생헤드에 의해 테이프상에 기록된 음성신호가 증폭기에 의해 증폭된 다음, 필터에 의해 우측 및 좌측챈널신호로 여파되고 증폭기를 통해 증폭되어 스피커로 출력되도록 되어져 있으므로 스피커로 출력되는 음성신호만으로는 테이프상에 기록된 신호가 스테레오방송인지 2개국어방송인지를 즉각적으로 구분할 수 없는 단점이 있었다.In order to reproduce the signal recorded on the tape, the audio signal recorded on the tape by the playhead is amplified by the amplifier, then filtered by the filter into the right and left channel signals and amplified by the amplifier and output to the speaker. Since only the audio signal output to the speaker can be distinguished immediately whether the signal recorded on the tape is stereo broadcast or bilingual broadcast.

이에 본 고안은 상기한 문제점을 개선하기 위하여 고안된 것으로서, 음성다중방송시 스테레오 방송인지 2개국어방송인지를 포함하는 식별신호(이하 I.D신호라 칭함)를 스테레오신호와 2개국어 신호에 함께 혼합한 후 이를 영상신호기록재생장치로써 테이프상에 함께 기록하며, 영상신호기록재생장치로 기록된 신호를 재생할때에는 검파부와 스테레오 신호판별부 및 2개국어신호판별부등으로 구성된 회로를 통해 재생되고 있는 신호가 스테레오 방송인지, 2개국어방송인지를 판별 및 표시할 수 있게 하여 사용상의 편의를 도모하고자 함에 그 목적이 있는 것이다.Therefore, the present invention is designed to improve the above-mentioned problems, and it is possible to mix an identification signal (hereinafter referred to as an ID signal) including a stereo signal or a bilingual broadcast in a multiplexed voice signal together with a stereo signal and a bilingual signal. Then, it is recorded together on the tape as a video signal recording and reproducing apparatus, and when the signals recorded by the video signal recording and reproducing apparatus are reproduced, they are reproduced through a circuit composed of a detector, a stereo signal discriminating unit, and a bilingual signal discriminating unit. The purpose of the present invention is to facilitate the use by identifying and displaying a stereo broadcast or a bilingual broadcast.

이하 본 고안의 구성 및 작용 효과를 예시도면에 의거하여 상세히 설명하면 다음과 같다.Hereinafter, the configuration and operation of the present invention will be described in detail with reference to the accompanying drawings.

본 고안은 방송국으로부터의 우측챈널신호(RCH)와 좌측챈널신호(LCH) I.D 신호가 입력되는 혼합기(1)에 증폭기(Amp1)와 헤드(H1~H4), 증폭기(Amp2), 대역통과필터(BPF1~BPF3) 및 증폭기(Amp3~Amp5)가 차례로 연결되고, 상기 증폭기(Amp3)(Amp4)에는 스피커(SP)가, 상기 증폭기(Amp5)에는 I.D신호검파부(2)가 각각 연결되며, 상기 I.D신호검파부(2)에는 필터(BPF4)(BPF5)와 스테레오신호판별부(3), 스테레오신호표시부(4), 2개국어신호판별부(5) 및 2개국어신호표시부(6)가 연결된 구조로 되어 있다.The present invention provides an amplifier (Amp 1 ), a head (H 1 ~ H 4 ), an amplifier (Amp 2 ) to the mixer (1) to which the right channel signal (RCH) and the left channel signal (LCH) ID signal from a broadcasting station are input. the ID signal band pass filter (BPF 1 ~ BPF 3) and an amplifier (amp 3 ~ amp 5) is connected in turn, wherein the amplifier (amp 3) (amp 4), the speaker (SP), the amplifier (amp 5) A detector 2 is connected to each other, and the ID signal detector 2 includes a filter BPF 4 , a BPF 5 , a stereo signal discriminating unit 3, a stereo signal displaying unit 4, and a bilingual signal discriminating unit. (5) and bilingual signal display section 6 are connected.

제1도는 상기한 구조로 되어 있는 본 고안의 회로도로서, 음성다중방송 매체로부터 FM변조되어 전송되는 우측챈널신호(RCH)와 좌측챈널신호(LCH)는 음성다중방송의 종류에 따라 AM변조되어 방송국으로부터 전송되는 I.D신호(I.D)와 함께 혼합기(1)에 입력되고, 상기 혼합기(1)에서는 우측챈널신호(RCH), 좌측챈널신호(LCH) 및 I.D신호(I.D)가 혼합된 후 증폭기(Amp1)를 매개하여 기록용헤드(H1)(H2)에 의해서 테이프상에 기록되어진다.1 is a circuit diagram of the present invention having the above-described structure, in which a right channel signal (RCH) and a left channel signal (LCH), which are FM-modulated and transmitted from a voice multiplexing medium, are AM-modulated according to the type of voice multicasting. It is input to the mixer 1 together with the ID signal ID transmitted from the mixer 1, and in the mixer 1, the right channel signal RCH, the left channel signal LCH, and the ID signal ID are mixed, and then the amplifier Amp. It is recorded on the tape by the recording head H 1 (H 2 ) via 1 ).

한편 상기한 방법에 의해 테이프상에 기록된 신호를 영상신호기록재생장치를 사용하여 재생하고자 할 경우, 재생용헤드(H3)(H4)에 의해서 재생된 영상신호는 증폭기(Amp2)에 의해서 증폭된 다음 대역통과필터(BPF1)에 의해 우측챈널신호(RCH)가 여파되고, 대역통과필터(BPF2)에 의해서는 좌측챈널신호(LCH)가 여파되며, 대역통과필터(BPF3)에 의해서는 I.D신호가 여파된다.On the other hand, when the signal recorded on the tape is to be reproduced by the video signal recording and reproducing apparatus by the above method, the video signal reproduced by the reproducing head H 3 and H 4 is transferred to the amplifier Amp 2 . the following band pass filter and the chaenneol signal (RCH) right filtered by (BPF 1), and may wake the chaenneol signal (LCH) left by the band pass filter (BPF 2), a band-pass filter amplified by (BPF 3) By, the ID signal is filtered out.

상기 대역통과필터(BPF1)(BPF2)에 의해 여파된 신호는 증폭기(Amp3)(Amp4)에 의해서 증폭된 다음 스피커(SP)를 통해서 외부로 출력되고, 또한 상기 대역통과필터(BPF3)에 의해 여파된 I.D신호는 증폭기(Amp5)에 의해서 증폭된 다음 검파부(2)에 입력되어 트랜스(T)를 유지시키게 되고, 상기 트랜스(T)에 의해서 유기된 신호는 다이오드(D1)에 의해 반파정류된 후 콘덴서(C1)에 의해 고역성분이 여파되며, 상기 여파된 신호는 저항(R2)(R3)과 대역통과필터(BPF1)(BPF2)를 매개하여 스테레오신호판별부(3)와 2개국어신호판별부(5) 내의 트랜지스터(TR1)(TR4)의 베이스에 인가되는바, 방송의 종류에 따라 I.D신호는 각기 다른 주파수 대역폭을 가지므로 I.D신호는 종류에 따라 (즉, 주파수 대역에 따라) 트랜지스터(TR1)(TR4)중 하나가 턴온되고, 상기 트랜지스터(TR1)(TR4)의 턴온에 의해 트랜지스터(TR2)(TR3)나 트랜지스터(TR5)(TR6)중 한 셋트가 턴오프되게 되며, B+전원이 스테레오신호표시부(4)나 2개국어신호표시부(6)의 저항(R9)(R17)를 매개하여 발광다이오드(LED1)나 발광다이오드(LED2)에 입력되어 이들을 발광시키므로 현재 재생되는 방송의 상태를 즉시 확인 판별할 수 있게 된다.The signal filtered by said band pass filter (BPF 1) (BPF 2) an amplifier (Amp 3) and through a next speaker (SP) amplified by the (Amp 4) output to the outside, and wherein said band pass filter (BPF The ID signal filtered by 3 ) is amplified by the amplifier Amp 5 and then input to the detector 2 to maintain the transformer T. The signal induced by the transformer T is a diode D. 1) half-wave rectified and then is the high frequency component filtered by the capacitor (C 1) by the said filtered signal by mediating the resistance (R 2) (R 3) and a band pass filter (BPF 1) (BPF 2) It is applied to the base of the transistors TR 1 and TR 4 in the stereo signal discriminating unit 3 and the bilingual signal discriminating unit 5, and since the ID signals have different frequency bandwidths depending on the type of broadcasting, Depending on the type (i.e., depending on the frequency band) one of the transistors TR 1 (TR 4 ) is turned on and the transistors TR 1 (T) The turn-on of R 4 causes one of the transistors TR 2 (TR 3 ) or TR 5 (TR 6 ) to be turned off, and the B + power supply is a stereo signal display section 4 or bilingual signal. The light emitting diode LED 1 or the light emitting diode LED 2 emits light through the resistors R 9 and R 17 of the display unit 6 so that the state of the broadcast currently being reproduced can be immediately confirmed. .

일예로 영상신호 기록재생장치의 테이프상에 음성다중방송의 스테레오방송신호가 녹음되어 있을 경우, 재생헤드(H3)(H4)에 의해 재생된 신호는 증폭기(Amp2)에서 증폭된 다음 대역통과필터(BFP1~BPF3)에 의해 우측챈널신호(RCH)와 좌측챈널신호(LCH) 및 스테레오방송 I.D신호로 여파되어 증폭된 다음 우측챈널신호(RCH)와 좌측챈널신호(CLH)는 스피커(SP)를 통해 외부로 송출되고, 스테레오방송 I.D신호는 다이오드(D1)와 저항(R1), 콘덴서(C1) 및 트랜스(T)로 구성된 검파부(2)에 의해 검파된 다음 저항(R2)을 매개하여 대역통과필터(BPF4)에 의해 여파된후(대역통과필터(BPF5)에 의해서는 그 주파수대역이 다르므로 여파되지 않음) 스테레오신호판별부(3)내에 있는 트랜지스터(TR1)의 베이스단자에 인가되므로 트랜지스터(TR1)는 턴온되고, 상기 트랜지스터(TR1)의 턴온에 의해 B+전원이 트랜지스터(TR1)를 통해 접지측으로 흐르게 되어 트랜지스터(TR2)의 베이스단자에는 로우신호가 인가되므로 트랜지스터(TR2)는 턴오프되며, 트랜지스터(TR2)의 턴오프에 의해 트랜지스터(TR3)의 베이스단자에 하이신호가 인가되므로 트랜지스터(TR3)도 턴오프되게 된다.For example, when a stereo broadcast signal of voice multicast is recorded on a tape of a video signal recording and reproducing apparatus, the signal reproduced by the reproduction head H 3 and H 4 is amplified by the amplifier Amp 2 and then the band. Filtered by a pass filter (BFP 1 ~ BPF 3 ) to the right channel signal (RCH), left channel signal (LCH) and stereo broadcast ID signal, amplified, and then the right channel signal (RCH) and left channel signal (CLH) is a speaker Transmitted to the outside via (SP), the stereo broadcast ID signal is detected by a detector (2) consisting of a diode (D 1 ) and a resistor (R 1 ), a capacitor (C 1 ), and a transformer (T), and then a resistance. The transistor in the stereo signal discriminating unit 3 after being filtered by the band pass filter BPF 4 via (R 2 ) (it is not filtered because the band pass filter BPF 5 is different in frequency). It applied to the base terminal of the (TR 1), so the transistor (TR 1) is turned on, the transistor (TR 1) Since the low signal base terminal of the B + power is flowing toward the ground via a transistor (TR 1), a transistor (TR 2) by a turn-on application of the transistor (TR 2) is turned off, the transistor (TR 2) Since the high signal is applied to the base terminal of the transistor TR 3 by turning off, the transistor TR 3 is also turned off.

그러므로 B+전원은 스테레오신호표시부(4)내의 저항(R9)을 매개하여 스테레오방송신호가 녹음되어 있는 것을 표시하는 발광다이오드(LED1)를 발광시키게 되므로 현재 재생되고 있는 신호가 스테레오로 녹음된 신호임을 즉시 식별할 수 있게 된다.Therefore, the B + power supply emits a light emitting diode (LED 1 ) indicating that a stereo broadcast signal is recorded through a resistor (R 9 ) in the stereo signal display unit (4), so that the signal currently being reproduced is recorded in stereo. You can immediately identify the signal.

또한, 영상신호기록재생장치의 테이프상에 음성다중 방송의 2개국어 방송신호가 녹음되어 있을 경우, 상기한 바와 같이 재생헤드(H3)(H4)에 의해 재생된 신호는 증폭기(Amp2)에서 증폭된 다음 대역통과필터(BPF1~BPF3)에 의해 우측챈널신호(RCH)와 좌측챈널신호(LCH) 및 2개국어방송 I.D신호로 여파되어 증폭기(Amp5)에 의해 증폭된 다음 우측챈널신호(RCH)와 좌측챈널신호(LCH)는 스피커(SP)를 통해 외부로 출력되고, 2개국어방송 I.D신호는 다이오드(A)와 저항(R1), 콘덴서(C1) 및 트랜스(T)로 구성된 검출부(2)에 의해 검출된 다음 저항(R10)을 매개하여 대응되는 대역통과필터(BPF4)만에 의해 여파된 후 2개국어신호판별부(5)내의 트랜지스터(TR4)의 베이스에 인가되므로 트랜지스터(TR4)는 턴온되고, 상기 트랜지스터(TR4)의 턴온에 의해 트랜지스터(TR5)(TR6)가 턴오프되게 되므로 B+전원이 2개국어 신호표시부(4)내의 저항(R17)을 매개하여 2개국어방송신호가 녹음되어 있는 것을 표시하는 발광다이오드(LED2)를 발광시킨다.In addition, when a bilingual broadcast signal of an audio multiplex broadcast is recorded on a tape of the video signal recording and reproducing apparatus, the signal reproduced by the reproduction head H 3 and H 4 as described above is converted into an amplifier Amp 2. Amplified by a band pass filter (BPF 1 ~ BPF 3 ) and then amplified by an amplifier (Amp 5 ) by a right channel signal (RCH), a left channel signal (LCH), and a bilingual broadcast ID signal. The right channel signal (RCH) and the left channel signal (LCH) are output to the outside through the speaker SP, and the bilingual broadcasting ID signal is a diode (A), a resistor (R 1 ), a capacitor (C 1 ) and a transformer. The transistor TR in the bilingual signal discriminating unit 5 after being detected by the detection unit 2 composed of (T) and then filtered by only the corresponding bandpass filter BPF 4 via the resistor R 10 . 4) because of the applied to the base transistor (TR 4) is turned on and the transistor by, the turn-on of the transistor (TR 4) (TR 5) (TR 6) Since B + to be turned off by the power-mediated resistance (R 17) in the bilingual signal display unit 4 to emit light, light emitting diodes (LED 2) indicating that the recorded signal is a bilingual broadcast.

따라서 지금 재생되고 있는 신호가 2개국어방송으로 녹음된 신호임을 즉시 식별할 수 있다.Therefore, it is possible to immediately identify that the signal being reproduced is a signal recorded by bilingual broadcasting.

또한 스테레오신호판별부(3)와 2개국어신호판별부(5)를 통해 스테레오신호와 2개국어신호가 모두 판별되지 않을 경우에는 트랜지스터(TR1)(TR4)의 베이스단자로 인가되는 신호가 없게 되므로 트랜지스터(TR1)(TR4)는 턴오프되고, 상기 트랜지스터(TR1)(TR4)의 턴오프에 의해 트랜지스터(TR3)(TR5)와 트랜지스터(TR3)(TR6)가 턴온되게 되므로 B+전원은 트랜지스터(TR3)(TR6)의 에미터단자를 통해 접지측으로 인가된다.In addition, when both the stereo signal and the bilingual signal are not discriminated through the stereo signal discriminating unit 3 and the bilingual signal discriminating unit 5, the signal applied to the base terminal of the transistors TR 1 and TR 4 . is not, so the transistor (TR 1) (TR 4) is turned off and the transistor (TR 1) (TR 4) transistor by the turn-off of the (TR 3) (TR 5) and the transistor (TR 3) (TR 6 ) Is turned on so that B + power is applied to the ground side through the emitter terminal of transistor TR 3 (TR 6 ).

따라서 스테레오방송표시 발광다이오드(LED1)와 2개국어 방송표시 발광다이오드(LED2)는 발광을 하지 않게 된다.Therefore, the stereo broadcast display LED 1 and the bilingual broadcast display LED 2 do not emit light.

상기한 바와 같이 본 고안은 신호검출부와 신호판별부 및 표시부를 설치하여 음성다중 방송으로 녹음된 테이프를 재생할 경우 자동으로 해당신호의 종류를 즉시 확인할 수 있는 효과가 있다.As described above, the present invention has the effect of automatically detecting the type of the signal immediately when playing the tape recorded by the voice multiple broadcast by installing a signal detector, a signal discrimination unit and a display unit.
