"Composite Video Baseband Signal" or "Composite Video, Blanking and Syncronization". - SCART
一種connector的標準,歐洲比較常用。內含Analog RGB video/S video, composite Video, analog stereo. - Composite Video
原來黑電視時代,信號只有gray level,後來彩色化,增加了RGB,所以就利用color space轉換,將RGB轉為Luminace (Y), Hue and Saturation。因為人類對Luminace 比較敏感,所以Luminace用0-4.2MHz來傳遞,Hue 和Saturnation就用3.58MHz sub-band來傳遞。這樣的信號就叫Composite Video.
