An early video codec (circa 1991) for use in compressing video for CD-ROM playback and distribution. Originally used in products by SuperMac (later Radius) since its creator, Peter Barrett, worked for SuperMac at the time. Later included in QuickTime and Video for Windows and in use for almost twenty years; deprecated to legacy codec status in QuickTime X, the Cinepak codec can still be used to encode and content encoded in Cinepak will still play back in QuickTime X. Based on vector quanitization, a compression scheme different from modern codecs which use either DCT or wavelet compression.
