Abstract

본 발명은 캡션디코더 내장형 브이씨알 관한 것으로, 종래에는 캡션디코딩 기능이 없는 티브이에서 캡션을 즐길 수 없는 문제점과 브이씨알에서 테이프를 재생하여 캡션정보를 시청할 경우 테이프 재생신호는 넌-스탠다드신호이어서 노이즈가 많아 수평, 수직분리에 어려움이 있어서 깨끗한 화면으로 시청할 수 없는 문제점이 있었다. 따라서, 본 발명은 캡션디코더가 내장된 브이씨알에 내장된 안테나를 통해 VHF/UHF신호를 받아 캡션디코더를 통해 티브이로 출력하도록 하여 캡션디코딩 기능이 없는 티브이에서도 캡션방송을 시청할 수 있도록 하고, 테이프에서 재생된 넌-스탠다드신호에 대하여 노이즈성분을 제거한 후 수평, 수직분리를 할 수 있도록 하여 정확한 수평, 수직분리를 함으로써 깨끗한 화면으로 시청할 수 있도록 한다.The present invention relates to a VCD with a built-in caption decoder, and has a problem in that it is not possible to enjoy a caption in a TV without a caption decoding function. There were a lot of difficulties in horizontal and vertical separation, there was a problem that you can not watch a clean screen. Therefore, the present invention receives the VHF / UHF signal through the antenna built in the V-Cal with the built-in caption decoder to output to the TV through the caption decoder to watch the caption broadcast in the TV without caption decoding function, on the tape After the noise component is removed from the reproduced non-standard signal, horizontal and vertical separation can be performed, so that accurate horizontal and vertical separation can be viewed as a clear picture.
