In the DVD-Video specification, the world is divided into 6 regions or locales so discs can be made to play in only one or a limited number of regions.
A method by which DVD playback is restricted by geographic region. For example, DVDs and DVD players sold in the United States, Canada, and Mexico are usually coded for Region 1. A Region 2 disc from Japan will not play on a Region 1 player, unless that player has been specially modified to do so.
DVDs are recorded and encoded for use in only one of six designated world regions. This system was developed to enable motion picture companies to release movies at different times in different regions.
