Separate Video[1], more commonly known as S-Video, also called
Y/C, and sometimes incorrectly [2] referred to as Super Video[3], is
an analog video signal that carries video data as two separate signals:
luma (luminance) and chroma (color). This differs from composite
video, which carries picture information as a single lower-quality
signal, and component video, which carries picture information as
three separate higher-quality signals. S-Video carries standard
definition video (typically at 480i or 576i resolution), but does not
carry audio on the same cable.
Source Input Format (SIF) defined in MPEG-1, is a video format that
was developed to allow the storage and transmission of digital video.
625/50 SIF format (PAL/SECAM) has a resolution of (360 or) 352 x
