	    <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>
