The significance of the first, second and third districts in the film industry.

Six regions divided by the Motion Picture Association of America for making area codes.

These six area codes are:

Region 1 (Region 1): the United States, Canada and the East Pacific Islands.

Region 2: Japan, Western Europe, Northern Europe, Egypt, South Africa and the Middle East.

Region 3: Taiwan Province Province, Hongkong, Korea, Thailand, Indonesia and other Southeast Asian countries.

Fourth area (Region4): Australia, New Zealand, Central and South America, South Pacific Islands.

Region 5: Russia, Mongolia, Indian Peninsula, Central Asia, Eastern Europe, North Korea, North Africa and Northwest Asia.

The sixth district: Chinese mainland.

Basically, when a DVD movie decides not to release the version of the sixth zone, we need to buy another set of equipment that can play non-sixth zone DVDs, so there is a saying that DVD players can't afford DVD discs; So there will be a cracked version of the DVD player, and the DVD package will also provide several opportunities to change the area code. However, I would like to remind my friends that only the DVDs released by the eight major American film companies have such restrictions, not the original specifications of DVDs. In other words, DVD films released by non-eight American film companies have no geographical restrictions, and are generally called FreeRegionCode or regional films.

The eight major American film companies:

"1, Warner Bros."

2. Colombia

3.20thCenturyFOX。

4. The most important thing

5. Universal

6. United Airlines (Joint Advertising) (007)

Mgm company

8. Walt Disney

The formulation of DVD specification dates back to February 65438+94. It is said that Toshiba and time warner Inc. took the lead in joining the alliance camp of 2 1 manufacturers such as ioneer/Zenith/Hitachi and MCA shortly after the founders of CD, Philips and Sony, announced the specifications of MMCD (Multimedia CD) read by precise coding technology and optical principle. With the introduction of SD (Super Density-Digital Video Disc) specification, optical discs can be recorded in two layers by using the lamination technology.

The two manufacturers do not give in to each other, so the American film industry and computer industry strongly demand that the two sides reach a unified specification. In June 5438+1February 995, the so-called preliminary specifications of DVD were finally determined, and "Top Ten authorized alliance manufacturers of DVD" were formed, which led the formulation of various specifications of DVD in the future. Although the specification was established, CEMA, the American Consumer Electronics Manufacturers Association, and Motion Picture Association of America, which has the most video resources, strongly urged Japanese DVD player manufacturers to install an "anti-copy control system" at this time, and the discs should be marked with different "area codes" for identification.

The Motion Picture Association of America aims to protect the software of the film industry from piracy, but the illegal film industry can still copy the whole CD. The circuit equipped with "anti-copy control system" not only failed to achieve the purpose of anti-copy, but also increased the cost of hardware manufacturers and even increased the complexity of software design.

As for the area code identification, the world is divided into six regions, and the DVD-Video released in each region can only be played by locally made CD players. The Motion Picture Association of America insists on using area code identification, mainly because each film has a different release time around the world. In order to avoid the loss of the benefits of DVD-Video listing before the film is staged, the area code is used to control it, so that after the film in an area is released, the DVD that has been overweight can be re-released. In order to take care of the rights and interests of the industry, the Motion Picture Association of America is quite strong, but the latest resolution is to let the optical drives in North America, Japan and Western Europe enjoy the freedom from regional code restrictions.
