Composite video is an interface for sending or receiving an analog video
signal. It is a composite of several signals, LUMA, CHROMA, and SYNC
(together referred to as CVSB or Composite Video Blanking and Sync).
LUMA represents the brightness or luminance of the picture and includes
synchronizing or SYNC pulses. CHROMA carries the color information.
Composite video interface usually connects a VHS tape player, DVD player,
or game console to a television.
