INFORMATIONSREGIONAL CODES1222554436Map of DVD RegionsWhat are regional codes?Motion picture studios want to control the home release of

21、movies in different countries because theater releases arentsimultaneous (a movie may come out on DVD in the US when its just hitting screens in Europe). Therefore they haverequired that the DVD standard include codes which can be used to lock out the playback of certain discs in certain geo-graphic

22、al regions. Players sold in each region will have that regions code built into the player. The player will refuse to playthese region coded discs which are not allowed in the region. However, regional codes are entirely optional. Discs withoutcodes will play on any player in any country. Some studio

23、s have already announced that only their new releases will haveregional codes. There are six regions: 1. United States and Canada 2. Europe and Japan 3. Far East (except Japan & China) 4.
