Field of the Invention [0001] The present invention relates to a television that mutes speech in case of poor reception sensitivity. In particular, the present invention relates to a television that detects the reception sensitivity of an RF signal from an antenna in a television and outputs more noise than the original sound when the reception sensitivity is not good. The present invention relates to a television that mutes the voice when receiving sensitivity is poor to mute the speaker. Referring to FIG. 1, the RF signal received at the antenna ANT is controlled by the microcomputer 1 at the tuner 2. FIG. And the output signal of the tuner 2 is processed by audio and video in the main IC 3, and then the video signal (or video signal) is output to the CRT 4, In addition, an audio signal (or an audio signal) is output to the speaker 5. Then, the microcomputer 1 senses the viewer's selection from the operation keys or the remote control formed on the operation panel of the television, and then controls the channel selection with the tuner 2 and the video control and audio control functions with the main IC 3. .

본 발명은 상기한 문제점을 해결하고 개선점을 달성하기 위해 안출한 것이다.상기한 본 발명의 목적을 달성하기 위한 기술적인 수단으로써, 본 발명의 수신감도 불량시 음성을 뮤트시키는 텔레비젼은 안테나로부터의 RF신호를 동조시키는 튜너와, 상기 튜너로부터의 신호를 각각 음성과 영상신호처리기능을 수행하여 영상은 CRT로 출력하고, 음성은 스피커로 출력하는 메인IC를 포함하는 텔레비젼에 있어서, 상기 메인IC로부터의 복합영상신호로부터의 동기신호를 분리한 후 적분하여 출력하는 동기분리회로부; 상기 동기분리회로부로부터의 검출신호와 내부에 설정된 기준신호를 비교한 다음에 검출신호가 기준신호보다 작을 경우에 수신불량감지신호를 출력하는 비교기; 상기 비교기로부터의 수신불량감지신호가 입력되는 경우에 스피커의 동작을 정지시키도록 제어하는 마이컴; 을 구비함을 특징으로 한다.The present invention has been made to solve the above problems and to achieve an improvement. As a technical means for achieving the object of the present invention described above, a television that mutes the voice in case of poor reception sensitivity of the present invention is an RF from an antenna. A television comprising a tuner for synchronizing a signal and a main IC for outputting a signal to a CRT and outputting a signal to a speaker by performing a voice and video signal processing function on the signal from the tuner, respectively. A synchronization separating circuit unit for separating and outputting the synchronization signal from the composite video signal; A comparator for comparing the detection signal from the synchronization separating circuit unit with a reference signal set therein and then outputting a reception failure detection signal when the detection signal is smaller than the reference signal; A microcomputer that controls the operation of the speaker to be stopped when a reception failure detection signal from the comparator is input; Characterized in having a.

제1도는 종래의 텔레비젼내부 회로블럭구성도이고, 제2도는 본 발명에 따른 텔레비젼내부 회로블럭구성도이다.1 is a conventional television internal circuit block configuration, and FIG. 2 is a television internal circuit block configuration according to the present invention.

이하, 본 발명에 따른 수신감도 불량시 음성을 뮤트시키는 텔레비젼의 바람직한 실시예를 첨부한 도면을 참조하여 설명한다. 본 발명에 참조된 도면에서 실질적으로 동일한 구성과 기능을 가진 구성요소들은 동일한 부호를 사용할 것이다.한 다음에 영상과 음성을 각각 출력하는 메인IC(3)와, 상기 메인IC(3)로부터의 영상을 화면출력하는 CRT(4)와, 상기 메인IC(3)로부터의 음성을 가청음으로 출력하는 스피커(5)로 구성한다. 그리고 상기 메인IC(3)는 내부에 영상신호처리블럭과 음성신호처리블럭을 포함하는 텔레비젼의 주신호처리IC이다.는 선택된 채널에 대한 음성이 출력되는 것이다.DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a preferred embodiment of a television for muting audio when reception sensitivity is poor will be described with reference to the accompanying drawings. In the drawings referred to in the present invention, components having substantially the same configuration and function will use the same reference numerals. Then, the main IC 3 which outputs the video and the audio, respectively, and the video from the main IC 3 will be described. And a speaker 5 for outputting audio from the main IC 3 as an audible sound. The main IC 3 is a main signal processing IC of a television including a video signal processing block and an audio signal processing block therein. The audio for the selected channel is output.

상술한 바와같은 본 발명에 따르면, 텔레비젼에서 안테나로부터의 RF신호의 수신감도를 검출하여 이 검출한 수신감도가 좋지 않을 경우에 원음보다 잡음(Noise)을 커게 출력하는 스피커를 뮤트(Mute)시키도록 함으로써, 수신감도가 불량한 경우에 시청자에게 불쾌감을 초래시키는 것을 사전에 방지하도록하는 특유의 효과가 있는 것이다.According to the present invention as described above, the TV detects the reception sensitivity of the RF signal from the antenna and mutes the speaker which outputs a noise larger than the original sound when the detected reception sensitivity is not good. Thus, there is a peculiar effect of preventing the viewer from causing discomfort in the event of poor reception sensitivity.
