DVD region codes is a DRM technique designed to allow motion picture studios to control aspects of a release, including content, release date, and especially, price, according to the region. DVD video discs may be encoded with a region code restricting the area of the world in which they can be played. The commercial DVD player specification requires that a player to be sold in a given place not play discs encoded for a different region.
Discs without region coding are called "all region" or "region 0" discs. In addition, many DVD players can be modified to be region-free, allowing playback of all discs. There are six different regions on the DVD, while Blu-ray Disc only has three. Also, major DVD player manufacturer countries (Japan, United States etc.) all have different regions, which caused problems for many. This is fixed in Blu-ray, as Japan (and other East Asian countries) and the Americas all have the same region.
6 Different Regions:
region 1: North America; U.S. territories; Bermuda
region 2: Europe; Western Asia; Kingdom of the Netherlands; Egypt, Japan, Lesotho, South Africa, Swaziland; British overseas territories, French overseas territories; Greenland
region 3: East and Southeast Asia
region 4: Oceania; Central and South America; Caribbean; Mexico
region 5: Africa, Central and South Asia, Belarus, India, Mongolia, North Korea, Russia, Ukraine
region 6: Mainland China
You might not think this Region Code thing is a big deal, but I believe it is. Guaranteed, if you travel a lot, you will be much impressive with this thing. Then how? How to deal with this issue? Buy a Region-Free DVD Player could be an easy solution.
When talking about the DVD region, I'm wondering how the movie industry plans to maintain this Region Code, when more and more people are downloading movies online and burning DVDs with downloaded videos, presumably from anywhere in the world.
