Abstract

본 발명은 PIP기능에 따른 주/부화면재생상태에서 선별뮤틈보드가 설정되는 경우에, 전송코드데이터가 검출되는 채널에 대해서 주음성으로서 절환되어 음성뮤트되도록 하되, 부음성에 대해서는 정상적인 음성재생이 가능하도록 하는 PIP기능을 갖춘 텔레비전의 주/부음성 부분뮤트장치를 제공한다.According to the present invention, when the selective mute board is set in the main / sub picture regeneration state according to the PIP function, the voice is switched to the main voice for the channel where the transmission code data is detected, but the voice mute is normal for the sub voice. A main / sub audio partial mute device of a television having a PIP function is provided.

그에 따라 본 발명은 복수의 선국수단(4,6,8,10)을 통해 동시 선국된 복수 채널의 영상신호가 주/부영상처리부(14,16)를 통해 각각 주/부화면으로서 영상처리되고, 그 음성신호가 주/부음성처리부(22,24)를 통해 각각 주/부음성으로서 음성처리되어 스피커와 헤드폰을 통해 각각 음성재생되도록 하는 PIP기능을 갖춘 텔레비전에 있어서; PIP기능의 실행과 주음성과 부음성의 선별뮤트모드의 실행을 키설정하는 기능설정수단(2)과, PIP기능에 따라 주/부화면과 주/부음성의 재생채널을 할당하기 위한 스위칭절환을 행하는 PIP모드스위치수단(12), 상기 주/부영상처리부(14,16)로부터의 각 주/부영상신호에 포함된 전송코드데이터를 검출하는 주/부코드검출수단(18,20), 상기 전송코드데이터가 검출된 채널의 음성신호가 주음성으로서 재생되도록 스위치절환하는 음성절환수단(26) 및, 상기 기능설정수단(2)에 의한 설별뮤트모드의 실행상태에서 상기 주/부코드검출수단(18,20)을 통해 전송코드데이터가 검출된 채널에 대해서 주음성재생되도록 상기 음성절환수단(26)을 스위칭제어함과 더불어, 상기 주음성재생되는 음성신호에 대한 음성뮤트를 행하는 제어수단(32)을 구비하여 구성된 것을 특징으로 한다.Accordingly, in the present invention, a plurality of channel video signals simultaneously tuned through a plurality of tuning means 4, 6, 8, and 10 are image processed as main / sub picture through the main / sub image processing units 14 and 16, respectively. In the television with a PIP function, the audio signal is processed as a main / sub-audio by the main / sub-audio processing section (22, 24), respectively, so that the audio is reproduced through the speaker and the headphone, respectively; A function setting means (2) for keying execution of the PIP function and execution of the selective mute mode of the main voice and the sub-voice, and switching switching for allocating the playback channels of the main / sub picture and the main / sub-audio according to the PIP function. PIP mode switch means (12) for performing the operation, main / sub code detection means (18, 20) for detecting transmission code data contained in each main / sub image signal from the main / sub image processing parts (14, 16), The main / minor code detection in the execution state of the description mute mode by the sound switching means 26 and the function setting means 2, which switches to switch the audio signal of the channel where the transmission code data is detected to be reproduced as the main sound. Control means for switching and controlling the voice switching means 26 so that the main voice is reproduced for the channel through which the transmission code data is detected through the means 18 and 20, and performing a voice mute for the voice signal reproduced for the main voice. Characterized in that it is provided with 32 do.

Claims

Video signals of a plurality of channels simultaneously tuned through a plurality of tuning means (4, 6, 8, 10) are image-processed as main / sub-screens respectively through the main / sub picture processor 14, 16, and the audio signal is In a television having a PIP function, which is processed as a main / sub-audio by the main / sub audio processing units 22 and 24, respectively, to reproduce the voice through the speaker and the headphone, the execution of the PIP function and the main and sub audio A function setting means (2) for key setting execution of the selective mute mode, and a PIP mode switch means (12) for switching switching for allocating a playback channel of a main / sub picture and a main / sub audio according to the PIP function; Main / sub code detection means (18,20) for detecting the transmission code data contained in each main / sub image signal from the main / sub image processing unit (14, 16), and the audio signal of the channel where the transmission code data is detected. Sound switching means 26 for switching the playback so that the audio is reproduced as the main voice; In the execution state of the selective mute mode by the function setting means (2), the voice switching means (26) is reproduced so that the main voice is reproduced for the channel through which the transmission code data is detected through the main / minor code detecting means (18, 20). And a switching means (32) for muting the voice signal to be reproduced with the main voice, in addition to switching control.
