| VHS Non-US (PAL) Article | DVD-Video is a consumer video format used to store digital video on DVD (DVD-ROM) discs, and is currently the dominant form of consumer video formats in the United States, Canada, Europe and Australia.Discs using the DVD-Video specification require a DVD drive and an MPEG-2 decoder (e.g., a DVD player, or a DVD computer drive with a software DVD player). Commercial DVD movies are encoded using a combination of MPEG-2 compressed video and audio of varying formats (often multi-channel formats as described below). Typical data rates for DVD movies range from 3-10 Mbit/s, and the bit rate is usually adaptive. A virtual machine implemented by the DVD player runs bytecode contained on the DVD. This is used to control playback and display special effects on the menus. The instruction set is called the Virtual Machine (VM) DVD command set. There are 16 general parameter registers (GPRM) to hold temporary values and 24 system parameters (SPRM). As a result of a moderately flexible programming interface, DVD players can be used to play games, such as the DVD re-release of Dragon's Lair, along with more sophisticated and advanced games such as Scene It, all of which can be run on standard DVD players.
