Abstract

본 발명은 비디오 컴팩트디스크의 콘트롤신호 검출방법에 관한 것으로, 특히 비디오 컴팩트디스크에 기록된 영상물중에 사용자가 원하는 부분의 영상만을 시청하기 위한 것으로, 서브코드상의 콘트롤신호중에 사용하지 않는 코드를 통해 콘트롤신호를 검출하는 방법에 관한 것이다.The present invention relates to a method of detecting a control signal of a video compact disc. More particularly, the present invention relates to a method of detecting a control signal of a video compact disc, The method comprising the steps of:

즉, 비디오 컴팩트디스크의 서브코드에 기록된 4비트의 콘트롤신호중에 사용되지 않는 두개의 4비트중 하나의 4비트는 해당하는 트랙이 경고문이나 광고문 또는 예고편임을 표시하고, 또 다른 하나의 4비트는 해당하는 트랙이 본래의 영상내용임을 표시하여, 사용자의 선택에 의해 비디오 컴팩트디스크를 초기재생시에 전반부 및 본편내용까지 재생하거나 본편재생만 초기재생시켜 비디오 컴팩트디스크의 재생에 편의를 제공한 것이다.That is, the 4 bits of one of the two 4 bits which are not used among the 4 bits of the control signal recorded in the subcode of the video compact disc indicate that the corresponding track is a warning word or an advertisement text or a trailer, and the other 4 bits It is displayed that the corresponding track is the original video content, and the video compact disc is reproduced from the first half and the main content at the time of initial reproduction by the user's choice or is initially reproduced only for the main piece reproduction, thereby facilitating the reproduction of the video compact disc.

비디오 컴팩트디스크의 콘트롤신호 검출방법Method of detecting control signal of video compact disk

본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음Since this is a trivial issue, I did not include the contents of the text.

제3도는 본 발명에 따른 비디오 컴팩트디스크의 서브코드와 프레임상에 4플래그비트로 제어신호가 기록된 상태의 도면.FIG. 3 is a diagram showing a state in which a control signal is recorded with four flag bits on a subcode and a frame of a video compact disk according to the present invention.

Claims (3)

비디오 컴팩트디스크의 서브코드에 기록된 일정수의 4비트의 콘트롤신호중에 사용되지 않는 두개의 4비트중 하나의 4비트는 해당하는 트랙이 경고문이나 광고문 또는 예고편임을 표시하고, 또 다른 하나의 4비트는 해당하는 트랙이 본래의 영상내용임을 표시하여, 사용자의 선택에 의해 비디오 컴팩트디스크를 초기재생시에 전반부 및 본편내용까지 재생하거나 본편재생만 초기재생시키는 비디오 컴팩트디스크의 콘트롤신호 검출방법.The 4 bits of one of the two 4 bits which are not used among the predetermined number of 4 bits of the control signal recorded in the subcode of the video compact disc indicates that the corresponding track is a warning word or an advertisement text or a trailer, Is a method for detecting a control signal of a video compact disc, which indicates that the corresponding track is the original video content and reproduces the first half and the main content at the time of initial reproduction or only the main piece reproduction at the initial stage. 제1항에 있어서, 상기 콘트롤신호의 4비트가 01x1일때에 해당트랙이 전반부이고, 콘트롤신호의 4비트가 11xx일때에 해당트랙이 본편임을 판단하는 비디오 컴팩트디스크의 콘트롤신호 검출방법.The method of claim 1, wherein when the 4 bits of the control signal are 01x1, the corresponding track is the first half, and when the 4 bits of the control signal are 11xx, it is determined that the track is the main track. 비디오 컴팩트디스크상에 기록된 서브코드의 Q채널을 읽어 들여 콘트롤신호가 11xx인가를 판단하는 단계(S100)(S101)와; 상기 단계(S100)(S101)에서 콘트롤신호가 11xx일 경우에 트랙번호를 저장수단에 저장하는 단계 (S102)와; 상기 단계 (S100)(S101)에서 콘트롤신호가 11xx가 아닐 경우에 TOC정보를 저장하는 단계 (S102)와; 로 이루어진 비디오 컴팩트디스크의 콘트롤신호 검출방법.(S100) (S101) of reading the Q channel of the subcode recorded on the video compact disc to determine whether the control signal is 11xx; (S102) storing the track number in the storage means when the control signal is 11xx in the step S100 (S101); Storing the TOC information (S102) when the control signal is not 11xx in the step S100 (S101); Wherein said control signal detecting means comprises: ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: It is disclosed by the contents of the first application.
