29、of movies in different countries because theater releases arenitsimultaneous (a movie may come out on DVD in the US when itis 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-gr

30、aphical regions. Players sold in each region will have that regionis 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

31、studios have already announced that only their new releases will haveregional codes. There are six regions:1. United States and Canada2. Europe and Japan3. Far East (except Japan & China)4.
