What Is a DVD Region Code?

The DVD area code is the information that follows the multifunctional digital optical drive module (dvd). You can only change the area code five times for the same multifunctional digital disc module. These five times include the area code changes you made under different windows operating systems. After you change the area code for the fifth time, the area code of your multifunctional digital optical drive module will be fixed at the area code selected for the fifth time. Even if you change your computer to use this module, you still cannot change the area code.

DVD region code

The DVD region code is jointly developed by the eight major film industries in the United States.

The world is now divided into six regions. The United States belongs to the first region, and mainland China belongs to the sixth region, as follows:

District 1: US, Canada

District 2: Western Europe, Japan, South Africa

District 3: Southeast Asia, Hong Kong, Macau, China, Taiwan, South Korea

District 4: Australia, Spanish, Latin America

District 5: Russia, Eastern Europe, Africa

District 6: Mainland China

Note: Latin America refers to the Americas region south of the United States, located between 32 ° 42N and 56 ° 54N, including Mexico, Central America,

Next-generation DVD area code technology:

HD-DVD: Divided into international version and Chinese version, the Chinese version is called "CH-DVD". Except for the same capacity and speed. HD-DVD / CH-DVD differs in various aspects such as light, storage method, and encoding format (a format independently developed by China). It can be said that they are two completely different optical disc technologies, and this is also a plan specially formulated by HD-DVD for serious piracy in China.

Blu-Ray: commonly known as Blu-Ray, the same partition. In addition to technically using more encrypted area codes, Blu-ray Group has also customized two data formats for movies and files. It is designed so that the disc player cannot read data discs, and the PC disc drive cannot read movie discs.

In mid-2008, SONY-DADC reached an agreement with relevant Chinese authorities to determine the format of Blu-ray discs in China. Note that the new Chinese Blu-ray format is not the area code divided by the previous Blu-ray camp.

Blu-ray discs in China use China's own encoding format, which is also used in EVD and CH-DVD. The effect level is said to be equivalent to MPEG-4.

* SONY-DADC: SONY Group's subsidiary responsible for optical discs and related technologies, headquartered in Austria.

If DVD players sold in China have region code restrictions, they can be viewed in the six regions and the entire region. If the DVD disc has strict regional restrictions, the DVD disc can only be played on a DVD player with the corresponding region code. In addition, if the decoder of the DVD player integrates various decoding / cracking technologies, it can also play some restricted DVD discs.

Refer to the method of cracking the regional code of the DVD drive on the PC side and the latest regional full firmware. ^[1]

It is important to point out that, on those independent DVD players (non-PC optical drives, such as portable DVDs, home audio and video DVD players), whether or not a DVD disc can be played, except for the problem of the area code, which cannot be played, decide Factors also include whether the media format in the DVD disc can be decoded and produced in accordance with the standards. (The kind of common super DVD player in China generally burns various decoders on the chip, which can decode common media formats on the market).
