Interlace The process of repeatedly displaying (scanning) all the lines in an odd field followed by displaying all the lines in an even field. Interlacing became part of video technology because early video equipment and televisions could not operate at high enough frequencies to scan every line on the display fast enough to produce a good quality image. It became so common that it has been adopted as a standard part of the video industry. See also: Field, Frame, De-interlace.

Luminance – The portion of the video signal that contains information on the relative brightness content of the image. The luminance channel of any video signal is the primary waveform encoded on the carrier signal. Traditional black- and-white televisions uses only a luminance channel (as a variable phase subcarrier). In S-video, the luminance signal (Y) is maintained as a separate channel.

Macrovision – A method for copy-protecting analog video outputs, developed by Macrovision Corporation. The DVD specification requires that this anti- taping mechanism be implemented on the S-video and Composite video outputs to prevent piracy or videotaping of copyrighted material. The copy protection operates by modifying the sync signal in such a way that VCRs are adversely affected (causing them to record an unwatchable image) but that display monitors and televisions are not.

MCI – A Microsoft standard method for applications to use for accessing multimedia functions (such as video or audio playback, volume control, etc.). MCI Commands are fully supported in the CineMaster driver, allowing applications developers to take advantage of the board’s capabilities without needing to write device drivers or other hardware-dependent code.

MPEG – The Moving Picture Experts Group. MPEG is a working group of ISO/IEC in charge of the development of international standards for compression, decompression, processing, and representation of moving pictures, audio and their combination.
