In general, the TV receiver is configured to output an audio signal of a received broadcast signal to a built-in speaker. Therefore, when watching a TV receiver, the voice signal output from the speaker in the TV receiver not only causes a lot of discomfort to those around who do not watch the TV receiver, but also causes problems such as disturbing sleep.

In order to solve this problem, a conventional TV receiver capable of remote control modulates a voice signal of a received broadcast signal and transmits it in an infrared ray, and receives the transmitted infrared ray from a remote control transmitter to listen remotely through an earphone or a speaker. I can do it.

However, according to this conventional technology, the voice signal of the received broadcast signal can be listened to alone, so that it does not disturb other people who do not watch the TV receiver, while listening to only one voice signal regardless of the voice multicasting. In stereo broadcasting, the stereo audio signal is transmitted in mono to listen to mono, and in other languages, only the main audio signal can be transmitted to listen to the main audio signal. there was.

The present invention has been made to solve the above-mentioned conventional problems, converts the voice multi-broadcast signal received from the TV receiver to infrared, and transmits the received signal to the earphone and speaker by the remote control transmitter It is an object of the present invention to provide an apparatus for listening to a voice multiple broadcast signal by allowing a user to remotely listen to a voice multiple broadcast signal by referring to the accompanying drawings.

1A and 1B are circuit diagrams showing the configuration of the apparatus for listening to a voice multiple broadcast signal according to the present invention. As shown in the drawing, the present invention remotely controls the TV receiver unit of FIG. 1A for receiving a broadcast signal and transmits the received audio signal, and receives and outputs the audio signal transmitted from the TV receiver unit. It consists of the remote control transmitter of FIG.

The TV receiver unit includes: a light receiver 1 for receiving a transmission signal from a remote control transmitter and outputting a foreign language selection signal (A / U), a stereo / mono selection signal (CS / MO), and a transmission command signal (RT); AND gates AD1, AD2, inverter IV1, and NOA for outputting a selection control signal of a voice signal in accordance with a stereo pilot signal PS, a foreign pilot signal PM, and an output signal of the light receiver 1; The voice selection control unit 2 includes a voice selection control unit 2 having gates NORI, NOR2 and buffers BF1-BF4 and voice signals A / R and U / L amplified by the voice amplifier 3. A switching unit 4 comprising switches SW1-SW5 for combined output in accordance with an output signal of < RTI ID = 0.0 >, < / RTI > and an analog multiplexer alternately outputting a level controlled signal from the switching unit 4 to the level control unit 5 ( 6), an A / D converter 7 for converting the output signal of the analog multiplexer 6 into a digital signal, and the A / D converter 7 outputted from the A / D converter 7. A parallel / serial converter 9 for serially converting the signal passed through the section 8, and a remote control for converting the output signal of the parallel / serial converter 9 into a remote control signal and transmitting it through the transmitter 11; The analog multiplexer 6, the A / D converter 7, the latch unit 8, the parallel / serial converter 9 and the remote control signal generator according to the oscillation signal of the signal generator 10 and the oscillator 12 ( A control signal generator 13 for generating a control signal of 10).

The remote control transmitter includes a light receiver 21 for receiving a transmission signal from a TV receiver, a voice signal separator 22 for separating a voice signal from an output signal of the light receiver 21, the light receiver 21 and an oscillator. A phase controller 24 for controlling the oscillation phase of the oscillator 23 by comparing the output signal phases of the 23 and a control signal generator 25 for generating a control signal in accordance with the output signal of the oscillator 23; The sub-control signal generator 26 generating the sub-control signal according to the output signal of the control signal generator 25 and the output signal of the audio signal separator 22 to the output signal of the sub-control signal generator 26. 2, the serial / parallel converter 28 and 29 for converting the output signal of the audio digital signal separator 27 in parallel, and the serial / parallel converter 28 and 29 ) And the signal passed through the latch section (30, 31) analog signal The D / A converters 32 and 33 for converting, the amplifiers 34 and 35 for amplifying the output signals of the D / A converters 32 and 33 and outputting them to earphones and speakers, and the volume control signals. The controller 36 is configured to control the amplification levels of the amplifiers 34 and 35 and to control and transmit the transmitter 37 according to a remote command.

The apparatus for listening to a voice multiple broadcast signal according to the present invention configured to transmit a control signal for transmitting a voice signal from the transmitter 37 of the remote control transmitter to the light receiver 1 of the TV receiver unit receives the received signal from the light receiver 1. By outputting the high potential to the RT, the high potential is applied to the control terminals of the switches SW4 and SW5 so as to connect the switches SW4 and SW5 of the switching unit 3 to the stereo pilot signal PS and the ear canal. As the AND gates AD1 and AD2, the inverter IV1, and the NOR and NOR2 of the voice selection control unit 2 are operated by the Korean pilot signal PM, the primary, secondary or stereo voices of different languages. And switches SW1-SW3 of the switching unit 3 are controlled to transmit mono voice.

If a stereo voice signal is received from a broadcasting station, the stereo pilot signal PS becomes high potential, and the bilingual pilot signal PM becomes low potential, so that the output of Noah gate NORI, NOR2 becomes low potential and the switch SW1. Low potential is applied to the control terminal of SW2).

Therefore, as the movable terminals of the switches SW1 and SW2 are connected to the fixed terminals b1 and b2, the output signals of the output terminals RI and LE of the audio amplifier 3, that is, the stereo audio signals, are respectively switched to the switches SW1 and SW4. And SW2 and SW5 are inputted to the level control unit 5 and at the same time the output terminal CS / MO of the light receiving unit 1 has a low potential during stereo selection, so that the switch SW3 is turned off.

When receiving a foreign language signal from a broadcasting station, the stereo pilot signal PS has a low potential, the bilingual pilot signal PM has a high potential, and the output terminal A / U of the light receiver 1 is selected. According to the output, either one of the switches (NORI, NOR2) selectively outputs a high potential so that one of the switches (SW1, SW2) is activated, and the output terminal (CS / MO) of the light receiver 1 Since the output is applied to the control terminal of the switch SW3, the switch SW3 is connected to the level control unit 3 through the output terminals RI and LE of the voice amplifier 3, and the voice multiple broadcasting is performed. If not, it is connected in the same way as the main audio signal selection.

On the other hand, when the voice signal of the selected mode, such as 2a degree, is input to the level control part 5, the signal is adjusted in size to the A / D converter 7 and input to the analog multiplexer 6, and the control signal of 2b degree is inputted. As it is input from the control signal generator 13 to the analog multiplexer 6, the output signals RI and LE are alternately output and input to the A / D converter 7. (I.e., RI output at fixed potential, LE output at low potential)

Therefore, the analog signal inputted to the A / D converter 7 receives the same sampling signal as the 2c diagram from the control signal generator 13, samples the points a and b of FIG. 2a, respectively, and converts the digital signals into 2d-f diagrams. The same output waveform is output through parallel data lines (D1-D3), where 2d and f represent the most significant bit and the least significant bit of digital data. In the present device, a pair of 6-bit signals using RI and LE data as a pair Will be sent in one word.

Accordingly, the output of the A / D converter 7 is inputted to the latch unit 8. The latch unit 8 receives the same clock signal as the second signal of the RI and LE data input in parallel and the A / D converter 7 ), And when both the RI and the LE data are latched by the latch unit 8, the same clock signal as the second signal is received, and the RI and LE data are simultaneously transferred to the parallel / serial converter 9 through the output terminals D1-D6. Will be entered.

Therefore, the parallel / serial converter 9 converts the parallel data in series and outputs a waveform such as a second chart including a dotted line to the remote control signal generator 10.

The signal input to the remote signal generator 10 receives a control signal, such as 2j degree, from the control signal generator 13 and transmits it through the transmitter 11, that is, transmits an infrared signal. In this case, RI and LE data are paired. The start pulse (SP) and the end pulse (EP) are added and sent to indicate the beginning and end of the 6-bit data transmission.

When the transmitted digital infrared signal is received by the light receiving unit 21 of the remote control transmitter, the digital infrared signal is converted into an electrical digital signal as shown in FIG. 3A and input to the voice signal separator 22 and the phase controller 24, and the phase controller 24 is used. In this case, the input signal is compared with the phase of the oscillation frequency of the oscillator 23, and the oscillation signal of the oscillator 23 is synchronized with the signal of the oscillation frequency of the oscillator 12 of the TV receiver.

Accordingly, the control signal generator 25 outputs a control signal for controlling the signal processing operation by using the synchronized oscillator 23 signal as a basic period pulse.

On the other hand, the voice signal separator 22 receives the control signal from the control signal generator 25, removes the start pulse SP and the end pulse EP, separates the 6-bit serial signal, and outputs the output waveform as shown in FIG. 3B. When inputted to the digital signal separator 27, the control signal is received from the sub-control signal generator 26 and separated into RI and LE digital signals as in the output waveform of the voice digital signal separator 27 as shown in FIG. 28 and 29, respectively.

Therefore, the serial / parallel converters 28 and 29 receive the same clock pulses as the 3d diagram from the sub-control signal generator 26, and convert the serial voice digital signals into parallel 3-bit signals through the data lines D1-D3. It is input to the latch portions 30 and 31.

In addition, the latch units 30 and 31 receive the same clock pulse as the 3e diagram from the control signal generator 25 to generate the RI digital signal having the same waveform as the 3f-g diagram and the LE digital signal having the 3h-j diagram to generate D / D. Inputs are made to the A converters 33 and 34, respectively.

Accordingly, the D / A converters 33 and 34 receive the control signal from the control signal generator 25 and reproduce each digital signal as an analog voice signal as shown in FIG. 2A, and input the same to the amplifiers 35 and 36. The volume width of the 34 and 35 is controlled by the controller 36 to reproduce the voice through the speaker and the earphone installed in the remote control transmitter.

As described in detail above, the present invention, since the remote control transmitter receives and outputs the voice multicast signal transmitted from the TV receiver, the people around the TV receiver can not hear the voice signal to remove the discomfort Of course, it does not interfere with bedtime.
