Understanding the DVD System
Digital Video Disk (DVD) stores and plays digital information, such as a movie, on a disk
similar in size to the common CD-ROM disk. DVD output is clearer, sharper, and uses a
higher color resolution than previous formats. Audio content is also sharper. DVD disks
store up to nine hours of exceptionally high quality video and multi-channel surround-
sound audio, interactive multimedia computer programs, or 30 hours of CD-quality audio.
DVD allows features that were impossible with movies (or games) on tape. DVD players
can play from any point on the disk. It can also pause, play in slow motion or fast forward,
or freeze frames. These random access features allow previously unheard of features
such as multiple endings for a movie, first-person interactive video games, and multiple
camera angles.
DVD can store multiple sound tracks, it supports up to eight languages for a single movie.
In addition, the format supports 32 closed caption tracks.
Region Codes
Motion picture studios want to control the home release of movies in different countries
because theater releases aren't simultaneous. They have required that the DVD standard
include codes that can be used to prevent playback of certain disks in certain
geographical regions. The player will refuse to play disks that are not allowed in that
region.
Regional codes are entirely optional for the maker of a disk. Disks without codes will play
on any player in any country. Most DVD-ROM drives let you change the region code a
few times, usually between 5 and 9. Once a drive has reached the limit it can't be
changed again unless the vendor or manufacturer resets the drive. There are 6 regions:
1 Canada, U.S., U.S. Territories
2 Japan, Europe, South Africa, Middle East (including Egypt)
3 Southeast Asia, East Asia (including Hong Kong)
4 Australia, New Zealand, Pacific Islands, Central America, Mexico, South
America, Caribbean
5 Former Soviet Union, Indian Subcontinent, Africa, N. Korea, Mongolia)
6 China
