Description
본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음Since this is an open matter, no full text was included.
제1도는 본 발명의 한 특성에 따른 디지탈 부분을 포함하는 텔레비젼 시스템에 대한 블록선도, 제2도는 제1도 배열의 어떤 특성을 이해하는데 유용한 타이밍 신호, 제3도는 NTSC합성 칼라텔레비젼 신호를 제1도배열의 표준규격에 따른 신호로 트랜스코딩할 때의 상대 샘플링시간을 이해하는데 유용한 타이밍선도, 제4도는 원래 샘플된 신호값에 대한 신 샘플점에서의 보간을 통해 트랜스코딩으로부터 야기된 에러를 이해하는데 도움이 되는 일반화된 파형도, 제5도는 트랜스코딩과 관련된 본 발명의 실시예에 대한 블록선도.1 is a block diagram of a television system including a digital portion in accordance with an aspect of the present invention, FIG. 2 is a timing signal useful for understanding certain characteristics of the FIG. 1 arrangement, and FIG. 3 is an NTSC composite color television signal. A timing diagram useful for understanding the relative sampling time when transcoding into a signal conforming to the standard of the array. FIG. 4 illustrates the error resulting from transcoding through interpolation at the new sample point for the original sampled signal value. A generalized waveform diagram that is helpful, FIG. 5 is a block diagram of an embodiment of the invention with respect to transcoding.
