Description

배밀주사 디지탈 TVDouble Exposure Digital TV

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

제2도는 본 발명에 따라 S-단자를 부착한 상태에서 영상신호를 수신하도록 하여 배밀주사하는 디지탈 TV의 개략적인 블록선도.2 is a schematic block diagram of a digital TV for double-scanning by receiving a video signal with an S-terminal attached thereto according to the present invention.

Claims (1)

배밀주사 디지탈 TV에 있어서, 영상신호를 휘도신호와 색신호로 분리하여 입력하는 S단자를 구비하고, S단자에 영상신호가 입력되면 Y신호를 선택하는 스위칭회로와, C신호가 아날로그 회로의 색차신호 분리회로를 경유하고, 멀티플렉스된 다음 A/D변환되게 하여 Y-채널 분리회로로부터의 C신호의 데이터 포맷과 동일한 신호를 Y-채널로부터의 C-신호가 없을 때 스위칭되어 수직 동기기간 이외의 기간에 메모리에 입력되게 하는 스위칭 회로들을 구비하여, 화질의 망실이 없도록 배밀주사하는 배밀주사 디지탈 TV.In a double-tight scan digital TV, the terminal comprises an S terminal for separating and inputting a video signal into a luminance signal and a color signal. Via a separation circuit, and then multiplexed and then A / D converted, the same signal format as the data format of the C signal from the Y-channel separation circuit is switched when there is no C-signal from the Y-channel so that it is out of the vertical synchronization period. A doublet scanning digital TV comprising switching circuits which are input into a memory in a period so as to double-tightly scan so that there is no loss of image quality. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
