The DVD region code is jointly formulated by the eight major film industries in the United States, in order to protect the rights and interests of movies in various regions.
The world is divided into six regions, and the DVD discs circulating in each region must be set with a film region code. As a result, theater or home users in each area cannot obtain cheap discs through parallel input or from low-cost areas, but must obtain them through normal channels, thus ensuring their own rights.
Therefore, the world's major film companies have jointly formulated this protection limit. This is the so-called CSS (Content Scrambling System) area code protection. DVD region codes limit the countries where DVD discs can be used.
For example: DVD discs encoded as North America (Region 1) will not play on players sold in Japan (Region 2). WinDVD provides users with five opportunities to choose the region code they need. When the number of selections is used up; WinDVD will be limited to the last region code. In the future, you can only play videos or all regions of the region code , Unlocked videos.
The world is now divided into six regions. The United States belongs to the first region, and the Chinese mainland belongs to the sixth region. Details are as follows:
District I: United States, Canada Region II: Western Europe, Japan, South Africa Region III: Southeast Asia, Hong Kong, China, Macau, China Taiwan Region IV: Australia, Spanish Latin America Region V: Russia, Eastern Europe, Africa Region VI: Mainland China
Note: Latin America refers to the area of ​​the Americas south of the United States, located between 32 ° 42 ′ north latitude and 56 ° 54 ′ south latitude, including Mexico, Central America, West Indies, and South America. Due to the long-term colonies of Spain and Portugal, which have been reduced to the Latin group, most of the languages ​​in the existing countries belong to the Latin family, so they are called Latin America.
There are thirty-four countries in Latin America: Mexico, Guatemala, Honduras, El Salvador, Nicaragua, Costa Rica, Panama, Cuba, Haiti, Dominica, Jamaica, Trinidad and Tobago, Barbados, Grenada, Dominican Confederation, Saint Lucia , Saint Vincent and the Grenadines, Bahamas, Guyana, French Guiana, Suriname, Venezuela, Colombia, Brazil, Ecuador, Peru, Saint Kitts and Nevis, Bolivia, Chile, Argentina, Paraguay, Uruguay, Belize, Ann Antigua and Barbuda.
The digital encryption of DVD movies is mainly encrypted by "CSS (Content Scrambling System)". After encryption, the data of these movies must be decoded before playing.
Because the DVD movie data is now protected by CSS, the images you watch in the DVD movie must be "decoded authorized", that is, you can use a legal decoding program to play it, whether it is used in the DVD player of home appliances or on the computer. Players such as DVD-ROM and PowerDVD play movies, and they must be decoded to play properly. The limitation of the region code makes the original DVDs you bought abroad brought back to China but cannot be played, because in CSS, your "decoding authorization" is limited to that you can watch DVDs in Region 6 (China) Movies, and DVD movies in other areas, cannot be watched without authorization.
In addition to setting a region code separately for DVD discs, there is also a full region type, which can be used on any region coded optical drive or player.
The DVD drive on the computer is generally set to have the opportunity to modify the area code 5 times, and the area code can be modified.
New generation DVD region code technology:
HD-DVD: Divided into international version and Chinese version, the Chinese version is called "CH-DVD". Except for capacity and speed. HD-DVD / CH-DVD differs in light, storage method, encoding format (a format independently developed by China) and other aspects. It can be said that the two disc technologies are completely different. This is also a plan specially formulated by HD-DVD for serious piracy in China.
BlueRay: Commonly known as Blu-ray, the same partition. In addition to technically using more encrypted region codes, Blu-ray Group has also customized two data formats for movies and files. It is designed so that the DVD player cannot read the data disc and the PC optical drive cannot read the movie disc.
In mid-2008, SONY-DADC reached an agreement with relevant Chinese departments to determine the Blu-ray Disc format in China. Note that the new Chinese Blu-ray format is not the region code divided by the previous Blu-ray camp.
China Blu-ray Disc uses China's own encoding format, which is also used in EVD and CH-DVD. The effect level is reported to be equivalent to MPEG-4.
