본 고안은 텔레비젼의 음성 다중 방송 수신기 각 방송 모우드에 따라 자동 절환되게한 음성 다중 모우드의 자동 전환회로에 관한 것이다.The present invention relates to an automatic switching circuit of an audio multiple mode which is automatically switched according to each broadcasting mode of an audio multicast receiver of a television.

현재 음성 다중 텔레비젼에서는 음성 다중 방송을 수신하고 이 수신된 방송이 스테레오나 제2외국어 방송을 포함하고 있을때 이 신호를 검파 증폭한후 스테레오 램프나 제2외국어 방송 램프를 점등시켜 현재 수신중인 방송을 사용자에게 알리고 사용자가 수동으로 수신중인 방송 모우드에 따라 절환시켜야 되는 번거러움이 수반되는 것이었다.Currently, voice multi-TV receives voice multi-cast and detects and amplifies this signal when the received broadcast includes stereo or second foreign language broadcasting, and then lights up the stereo lamp or second foreign language broadcasting lamp to use the currently receiving broadcast. This was accompanied by the hassle of notifying the user and switching according to the broadcasting mode that the user was manually receiving.

본 고안은 이와 같은 점을 감안하여 음성 다중 방송 수신 모우드에 따라 자동적으로 방송 모우드가 절환되게 함으로써 다시 절환 스위치를 구동시켜야 되는 불편함을 해소시킬 수 있게 한 것으로 방송 표시용 발광다이오드의 출력에 따라 구동되는 자동절환 회로의 출력이 모우드 전환 회로를 제어하여 음성 다중 처리 집적 소자에 인가되는 전압이 제어되게 구성시킨 것이다.In view of the above, the present invention enables the broadcast mode to be automatically switched according to the voice multicast reception mode, thereby eliminating the inconvenience of switching the switch again. The output of the automatic switching circuit is configured to control the mode switching circuit so that the voltage applied to the voice multi-processing integrated device is controlled.

이를 첨부 도면에 의하여 상세히 설명하면 다음과 같다.This will be described in detail with reference to the accompanying drawings.

본 고안에서 사용되는 음성다중 처리 집적소자(IC1)내에는 제2외국어 램프 구동부(1) 및 스테레오 램프 구동부(2)가 내장되어 있어 수신중인 방송 상태에 따라 발광다이오드(LED1)(LED2)의 캐소우드측에 「레벨」신호가 출력되어 점등되게 구성하고, 내부에 모우드 선택부(3)와 연결된 단자(P9)(P10)의 인가 전압에 따라 각 방송 모우드로 전환되게 구성한 것으로 텔레비젼에 널리 사용되고 있는 음성다중 처리 집적소자(IC1)를 사용하고 있다.Within the multiplex processing integrated device (IC 1) used in the present design is a built-in second language lamp drive unit (1) and the stereo lamp driver (2) light-emitting diode in accordance with the broadcasting state is being received (LED 1) (LED 2 'Level' signal is output and turned on at the cathode side of the PC), and it is configured to switch to each broadcasting mode according to the applied voltage of the terminal P 9 (P 10 ) connected to the mode selector 3 therein. The audio multi-processing integrated device (IC 1 ), which is widely used for televisions, is used.

그리고 도시되지 아니한 수동조작 스위치가 연결된 마이크로프로세서(MIC)의 출력이 다이오드(D1-D3)를 통하여 저항(R6-R12)과 연결된 트랜지스터(Q3-Q7)의 출력이 제어되게 모우드 절환회로(5)를 구성시켜 음성다중 처리 집적소자(IC1)의 단자(P9)(P10)에 인가되는 전압이 제어되게 구성시키고 발광다이오드(LED1)(LED2) 및 모우드 전환회로(5) 사이에 PNP 트랜지스터(Q1)(Q2)를 통하여 스테레오 자동 절환 스위치(SW1) 및 제2외국어 자동 절환 스위치(SW2)로 구성된 자동절환 회로(4)를 구성시켜 된 것이다.And the output of the microprocessor (MIC) to which the manual operation switch (not shown) is controlled so that the outputs of the transistors (Q 3 to Q 7 ) connected to the resistors (R 6 to R 12 ) are controlled through the diodes (D 1 -D 3 ). The mode switching circuit 5 is configured so that the voltage applied to the terminals P 9 and P 10 of the voice multi-process integrated device IC 1 is controlled, and the light emitting diodes LED 1 and LED 2 are switched. The automatic switching circuit 4 composed of the stereo automatic switching switch SW 1 and the second foreign language automatic switching switch SW 2 is configured between the circuits 5 through the PNP transistors Q 1 and Q 2 . .

이와 같이 구성된 본 고안에서 음성다중 방송이 수신될 경우 텔레비젼 셋트는 이 수신된 신호가 스테레오 방송인지 제2외국어 방송인지를 음성다중 처리 집적소자(IC1)에서 판단하게 되며 스테레오 방송인가시에 스테레오 램프 구동부(2)의 「L레벨」신호에 의하여 발광다이오드(LED1)가 점등하게 되고 제2외국어 방송 인가시에는 제2외국어 램프구동부(1)의 「L레벨」신호에 의하여 발광다이오드(LED2)가 점등하게 된다.In the present invention configured as described above, when a voice multiple broadcast is received, the television set determines whether the received signal is a stereo broadcast or a second foreign language broadcast by the voice multi-processing integrated device (IC 1 ). The light emitting diode LED 1 is turned on by the "L level" signal of (2). When the second foreign language broadcasting is applied, the light emitting diode (LED 2 ) is turned on by the "L level" signal of the second foreign language lamp driver 1. Lights up.

따라서 발광다이오드(LED1)(LED2)가 점등된 상태에서 사용자는 도시되지 아니한 스위치로 수신방송 모우드 절환을 시키면 마이크로프로세서(MIC)의 출력단자(P1-P3)의 상태 신호에 의하여 모우드 절환 회로(5)를 제어하여 모우드 선택부(3)와 연결된 단자(P9)(P10)의 인가되는 상태 신호에 따라 음성다중 처리 집적소자(IC1)의 모우드 선택부(3)에 의하여 인가되는 방송 모우드로 전환되는 것으로 단자(P9)(P10)의 상태 신호에 따라 전환되는 방송 모우드는 다음표와 같다.Therefore, when the user switches the broadcast mode with a switch (not shown) in the state where the light emitting diodes (LED 1 ) (LED 2 ) are lit, the signal is output by the status signals of the output terminals (P 1 -P 3 ) of the microprocessor (MIC). By the mode selector 3 of the voice multi-processing integrated device IC 1 according to the applied state signal of the terminal P 9 (P 10 ) connected to the mode selector 3 by controlling the switching circuit 5. The broadcast mode that is switched to the applied broadcast mode and is switched according to the state signals of the terminals P 9 and P 10 is shown in the following table.

[표 1]TABLE 1

즉, 본 고안에서 스테레오 방송 모우드 선택시에 마이크로프로세서(MIC)의 출력단자(P3)에는 「H레벨」신호, 출력단자(P1)(P2)는 「L레벨」신호가 출력되는 것으로 단자(P3)의 「H레벨」신호, 출력단자(P1)(P2)는 「L레벨」신호가 출력되는 것으로 단자(P3)의 「H레벨」신호는 P3→Q6도통→Q7차단→단자(P1>)는 무신호 상태가 되고 단자(P1)의 「L레벨」→Q3으로 →Q4오프단자(P2)의 「L레벨」→Q5오프가 되어 단자(P9)도 무신호 상태가 되어 표와 같이 모우드 선택부(3)는 스테레오 방송을 수신하게 된다.That is, in the present invention, when the stereo broadcast mode is selected, the "H level" signal is output to the output terminal P 3 of the microprocessor MIC, and the "L level" signal is output to the output terminals P 1 and P 2 . The "H level" signal of the terminal P 3 and the "L level" signal are output from the output terminals P 1 and P 2 , and the "H level" signal of the terminal P 3 is P 3 → Q 6. → Q 7 shut-off → terminal (P 1 >) is in the no signal state, and “L level” of terminal P 1 → Q 3 → “L level” of Q 4 off terminal (P 2 ) → Q 5 off Thus, the terminal P 9 is also in a no signal state, and the mode selector 3 receives the stereo broadcast as shown in the table.

또한 수동으로 제2외국어 방송으로 절환시에는 마이크로프로세서(MIC)에서 모우드 제어하는 기능은 종래와 동일한 것이다.In addition, when manually switching to the second foreign language broadcasting, the function of mode control in the microprocessor (MIC) is the same as in the related art.

그러나 본 고안에서는 스테레오 자동절환 스위치(SW1) 및 제2외국어 자동 절환 스위치(SW2)를 모두 접속시키면 방송신호 인가에 따라 자동절환 회로(4)에 의하여 각 방송 모우드가 자동으로 전환하게 되는 것으로 스테레오 발광다이오드(LED1)가 점등된 상태에서 캐소우드측이 「L레벨」이 되므로 PNP트랜지스터(Q1)가 도통하여 스테레오 자동절환 스위치(SW1)를 통하여 Q6은 →Q7오프→P10이 무신호 상태가 되고 트랜지스터(Q3)(Q5)에는 아무런 전원이 인가되지 아니하는 상태가 되어 단자(P9)도 무신호 상태가 되어 스테레오 방송 모우드로 전환된다.However, in the present invention, if both the stereo automatic switching switch (SW 1 ) and the second foreign language automatic switching switch (SW 2 ) are connected, each broadcasting mode is automatically switched by the automatic switching circuit (4) in accordance with the application of the broadcast signal. Since the cathode side becomes "L level" while the stereo LED (LED 1 ) is turned on, the PNP transistor (Q 1 ) is turned on so that Q 6 is turned off from Q 7 through the stereo automatic switching switch (SW 1 ). 10 becomes a no-signal state, no power is applied to the transistors Q 3 and Q 5 , and the terminal P 9 also becomes a no-signal state and is switched to the stereo broadcast mode.

그리고 발광다이오드(LED2)가 점등되는 경우는 PNP트랜지스터(Q2)가 도통하여 제2외국어 자동 절환 스위치(SW2)를 통하여 출력되는 「H레벨」신호가 다이오드(D2)로 출력하게 되므로 이때에는 상술한 바와 같이(표 참조) 모우드 선택부(3)와 연결된 단자(P9)는 「L레벨」단자(P10)는 무신호 상태가 되어 제2외국어 방송수신 모우드로 전환되는 것이다.When the light emitting diode LED 2 is turned on, the PNP transistor Q 2 is turned on so that the "H level" signal outputted through the second foreign language automatic switching switch SW 2 is output to the diode D 2 . At this time, as described above (refer to the table), the terminal P 9 connected to the mode selector 3 has the "L level" terminal P 10 in a no-signal state and is switched to the second foreign language broadcast reception mode.

이상에서와 같이 본 고안은 종래와 같이 수동으로 방송 모우드를 절환시킬 수 있는 동시에 자동절환 회로(4)가 발광다이오드(LED1)(LED2)의 출력에 따라 구동된 후 모우드 전환회로(5)를 제어하여 수신되는 방송 신호에 따라 각 방송 모우드를 자동 절환시켜야 되는 불편함을 해소시킬 수가 있는 것이다.As described above, the present invention can switch the broadcasting mode manually as in the related art, and at the same time, the automatic switching circuit 4 is driven according to the output of the light emitting diodes LED 1 and LED 2 and then the mode switching circuit 5. It can eliminate the inconvenience of having to automatically switch each broadcast mode according to the received broadcast signal by controlling the.
