DVD region codes are a DRM scheme. DVD video discs may be encoded with a region code restricting the area of the world in which they can be played. Discs without region coding are called all region or region 0 discs.
The commercial DVD player specification requires that a player to be sold in a given place not play discs encoded for a different region (region 0 discs are not restricted). The purpose of this is to allow motion picture studios to control aspects of a release, including content, release date, and, especially, price, according to the region. Many DVD players are or can be modified to be region-free, allowing playback of all discs.
