| VCD, also called video CD is a compact disk
format based on the CD-ROM
XA standard which is specifically designed for MPEG-1 video and
additional interactive capabilities. A VCD disk holds 72-74 minutes of
video at near VHS resolution with a data transfer rate of 1.44 Mbps. VCD's
can be played on a dedicated VCD player, a CD-i player, on some CD-ROM
drives, and on some DVD players.
Introduced in 1993 by JVC, Philips, SONY and
Matsushita the specifications for VCD are published in the White Book.
Uncompressed video data requires about 5 MB of drive
space for one second of video so without compression a CD would only hold
a couple of minutes of video. VCD therefore requires the file to be
compressed to MPEG-1 and then formatted to include CD-i runtime
capabilities.
