<entry>Video decoder, the basic function of the video decoder is to
accept analogue video from a wide variety of sources such as
broadcast, DVD players, cameras and video cassette recorders, in
either NTSC, PAL or HD format and still occasionally SECAM, separate
it into its component parts, luminance and chrominance, and output
it in some digital video standard, with appropriate embedded timing
signals.</entry>
