A video format for displaying full-length digital movies. A number of manufacturers are just beginning to sell DVD-Video players, which attach to a television just like a videocassette player. Unlike DVD-ROMs
, the Digital-Video format includes a Content Scrambling System (CSS)
to prevent users from copying discs. This means that today’s DVD-ROM players cannot play DVD-Video discs without a software or hardware upgrade to decode the encrypted discs.
