Regional Locking and Codes|Why Can't I play all DVD's

Most of us may have observed that we can play certain Blue-ray discs and DVD's on certain machines that we own but other don't play at all.You might have got this question many times but there is a main reason behind this thing. And that thing is Regional Locking and Codes.

Every original  DVD and Blue-ray Disc (which are authorised) is having certain Regional codes associate with it and DVD and Blue-ray players also have regional codes that is associated with them. So this means That DVD disc only play in those players which are having the same Regional codes.So this mean if  the Disc and players having different codes they won't be compatible to each other.

What is the use of Regional Codes:
                     These Regional codes help Movie Studios,Game Companies and other media distribution companies can control when and where there content can be viewed.For example if we take movies as example ,Normally movies are released at different dates in different companies.So Regional Locking helps to control that.Now you might be thinking what are those regions.There are totally six regions and each region is having a certain code.
Lets see the six regions:

Region 1 : United States and Canada with region code 01.
Region 2 : Europe and Japan with region code 02.
Region 3 : South East Asia with region code 03.
Region 4 : Latin America and Australia with region code 04.
Region 5 :  Russia and rest of asia and Africa with 
                     region code 05.
Region 6 : China with region code 06. 

Below Figure shows how the world is divided into regions :

Thus in order to enjoy movies in your area , you should have a player that is having a region code which is similar to that of Disc's. 

LAST WORDS : 
                         Regional Codes is a technique designed to allow the Movie distributors to control release ,release date and prices according to the region.
