Abstract

본 발명은 한 채널의 방송에서 주음성, 부음성, 또는 주음성 및 부음성을 선택적으로 출력할 수 있는 음성다중텔레비전수상기에 관한 것으로서, 특히 음성다중방송시 또는 스테레오방송시 시청자의 선택에 따라서 주음성이 좌, 우측의 스피커중에서 시청자에게 가까운 스피커에서 출력되도록 할 수 있는 음성다중텔레비전수상기의 주, 부음성 스위칭장치 및 그 방법에 관한 것이다.The present invention relates to a voice multiple television receiver capable of selectively outputting a main voice, a sub voice, or a main voice and a sub voice in a single channel broadcast, and in particular, according to a viewer's selection during voice multi broadcasting or stereo broadcasting. The present invention relates to a main and sub-audio switching device and a method of a voice multiple television receiver capable of outputting audio from a speaker close to a viewer among left and right speakers.

본 발명은 마이크로프로세서(11)의 제어에 따라 상기 음성다중모듈(20)에서 출력되는 주음성신호와 부음성신호를 스위칭하여 음성처리부(21)로 출력하는 스위칭부(30)를 구비하여, 음성다중모듈(20)로부터의 신호에 의해서 방송이 음성다중방송인지를 판단하고, 음성다중방송인 경우 키입력부(9)로부터의 신호에 의해서 주음성과 부음성이 동시에 출력되는 모드인지를 판단하고, 그 모드인 경우 키입력부(9)로부터 주, 부음성을 스위칭하라는 스위칭 신호가 있는지를 판단하여, 키입력부(9)로부터 주, 부음성의 스위칭신호가 있는 경우에 스위칭부(30)를 제어하여 주음성신호와 부음성신호를 스위칭하는 것을 특징으로 한다.The present invention includes a switching unit 30 for switching the main audio signal and the sub-audio signal output from the voice multiplex module 20 under the control of the microprocessor 11 and outputting the audio signal to the voice processing unit 21. It is determined whether the broadcast is a voice multicast by the signal from the multi-module 20, and in the case of the voice multicast, it is determined whether the main voice and the sub-voice are simultaneously output by the signal from the key input unit 9, and In the case of the mode, the key input unit 9 determines whether there is a switching signal for switching the main and sub negatives, and when the main and sub negative switching signals are received from the key input 9, the switching unit 30 is controlled. It is characterized by switching the audio signal and the sub-audio signal.

본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음Since this is an open matter, no full text was included.

제 2 도는 본 발명에 따른 주, 부음성스위칭장치가 구성된 음성다중텔레비전수상기의 개략적인 블럭도.2 is a schematic block diagram of a voice multiple television receiver configured with a main and sub voice switching device according to the present invention.

Claims

In the voice multiple television receiver comprising a key input unit (9), a microprocessor (11) for controlling the entire apparatus, a voice multiple module (20) for outputting a main voice signal and a sub voice signal, and a voice processor (21), And a switching unit 30 for switching the main audio signal and the sub-audio signal output from the voice multiplexer module 20 and outputting the main audio signal and the sub-audio signal to the voice processing unit 21 under the control of the microprocessor 11. (9) is provided with a switching key to enable the microprocessor (11) to apply a signal to switch the main and sub-audio mutually, the main, sub-voice switching apparatus of the voice multiple television receiver.

The first step of determining whether the broadcast is a voice multicast by the signal from the voice multiplexer module 20. In the case of voice multicasting, is the mode in which the main voice and the sub-voice are simultaneously output by the signal from the key input unit 9? The second step of determining the second, the main, when the negative voice mode is output at the same time, the third step of determining whether there is a switching signal for switching the main, negative voice from the key input unit 9, and the main from the key input unit 9 And a fourth step of controlling the switching unit 30 to switch the main audio signal and the sub-audio signal when there is a sub-negative switching signal. .
