MPEG

M oving P ictures E xperts G roup systems boards and compression standards (e.g., MPEG-2 and MPEG-1) for the most popular emerging form of compressed full-motion video standard for computer file storage. MPEG compression requires MPEG playback boards and/or MPEG authoring boards such as the Optibase MPG-1000 digital video codec (compression/decompression) board (800-451-5101). Although MPEG-2 is superior to MPEG-1, MPEG-2 requires at least quad speed CD-ROMs that, thereby, limits the use of MPEG-2 in the commercial market. MPEG-2 works much better with CD-DVD . However, even MPEG-1 is considered a better video compression alternative than its competitors. Full-motion video at over 30 frames per second takes up so much digitized storage that video must be compressed to make it more useful in hypermedia. In 1996, Miro Computer Products (415-855-0955) introduced the first JPEG video capture card for less than $1,000 that will encode (capture) video in compressed MPEG format. MPEG video files have an mpg file extension and will not run on computers that do not have special MPEG playback hardware/software installed. MPEG playback hardware is becoming standard in most new computer models.
