There are six different official regions and two informal variations. DVDs may use one code, a combination of codes (Multi-Region), most codes (Region 0) or every code/no codes (Region All). The commercial DVD player specification requires that a player to be sold in a given place not play discs encoded for a different region; however, region-free DVD players are also commercially available. In addition, many DVD players can be modified to be region-free, allowing playback of all discs.

Any combination of regions can be applied to a single disc. For example, a DVD designated Region 2/4 is suitable for playback in Western Europe, Oceania, and any other Region 2 or Region 4 area. So-called "Region 0" and "ALL" discs are meant to be playable worldwide.

The term "Region 0" also describes the DVD players designed or modified to incorporate Regions 1–6, thereby providing compatibility with most discs, regardless of region. This apparent solution was popular in the early days of the DVD format, but studios quickly responded by adjusting discs to refuse to play in such machines. This system is known as "Regional Coding Enhancement". In turn, region-free players have all eight flags set, similar to Region ALL DVDs. Many also include RCE breaks, to skip repeating menus or bypass static images.

Region-code enhanced

Region-code enhanced, also known as just "RCE" or "REA", was a retroactive attempt to prevent the playing of one region's discs in another region, even if the disc was played in a region-free player. The scheme was deployed on only a handful of discs. The disc contained the main program material region coded as region 1. But it also contained a short video loop of a map of the world showing the regions, which was coded as region 2, 3, 4, 5, and 6. The intention was that when the disc was played in a non-region 1 player, the player would default to playing the material for its native region. This played the aforementioned video loop of a map, which was impossible to escape from, as the user controls were disabled.

However, the scheme was fundamentally flawed, as a region-free player tries to play a disc using the last region that worked with the previously inserted disc. If it cannot play the disc, then it tries another region until one is found that works. RCE could thus be defeated by briefly playing a "normal" region 1 disc, and then inserting the RCE protected region 1 disc, which would now play. RCE caused a few problems with genuine region 1 players.

many "multi-region" DVD players defeated regional lockout and RCE by automatically identifying and matching a disc's region code and/or allowing the user to manually select a particular region. Some manufacturers of DVD players now freely supply information on how to disable regional lockout, and on some recent models, it appears to be disabled by default. Computer program

is relatively small, allowing the distributor a great deal of flexibility in pricing.

Another purpose is controlling release dates. A practice of movie marketing threatened by the advent of home video is to release a movie to theaters, and for general sale, later in some countries than in others. Videotapes were inherently regional since formats had to match those of the encoding system used by television stations in that particular region, such as NTSC

, although from early 1990s PAL machines increasingly offered NTSC playback. DVDs are less restricted in this sense, and region coding allows movie studios to better control the global release dates of DVDs.

Thirdly, the copyright in some titles has different owners in different territories. Region coding allows copyright holders to prevent a DVD from being purchased from a region from which they do not derive royalties

) respectively. Strictly speaking, NTSC, PAL and SECAM are all analog chroma-encoding formats which have no relevance in the digital domain (as evident in the conflation of PAL and SECAM, which are actually two distinct analog color systems). However, these terms continue to be used (improperly) as a method of identifying refresh rates and vertical resolution.

NTSC is the analog color TV format historically associated with the United States, Canada, Japan, Mexico, Philippines, Taiwan, and other countries. PAL is the analog color TV format historically associated with most of Europe, most of Africa, China, India, Australia, New Zealand, Israel, North Korea, and other countries (and Brazil, but using the refresh rate and resolution commonly associated with NTSC). Some DVD players only play discs identified as NTSC or PAL, while others can play both standards.

In general, it is easier for consumers in PAL countries to view NTSC DVDs than vice versa. Almost all DVD players sold in PAL countries are capable of playing both kinds of discs, and most modern PAL TVs can handle the converted signal. However, most NTSC players cannot play PAL discs, and most NTSC TVs do not accept 576i video signals. Those in NTSC countries, such as in North America, generally require both a region-free, multi-standard player and a multi-standard television to view PAL discs, or a converter box, whereas those in PAL countries generally require only a region-free player. There are also differences in pixel aspect ratio

(720 × 480 vs. 720 × 576) and display frame rate (29.97 vs. 25). Again, NTSC discs can be played on most DVD systems worldwide, while PAL discs play on very few players outside of PAL/SECAM countries. However, as of 2009, around 80% of NTSC TVs and DVD players are capable of playing PAL DVDs, due to them being upgraded with converter systems.

Most computer-based DVD software and hardware can play both NTSC and PAL video and both audio standards.

NTSC discs may be output from a PAL DVD player in three different ways:

at the factory. This flag holds the region number that the machine is allowed to play. Region-free players are DVD players shipped without the ability to enforce regional lockout (usually by means of a chip that ignores any region coding), or without this flag set.

However, if the player is not region-free, it can often be unlocked with an unlock code entered via the remote control

Remote control

A remote control is a component of an electronics device, most commonly a television set, used for operating the television device wirelessly from a short line-of-sight distance.The remote control is usually contracted to remote...

. This code simply allows the user to change the factory-set configuration flag to another region, or to the special region "0". Once unlocked this way, the DVD player allows the owner to watch DVDs from any region. Many websites exist on the Internet offering these codes, often known informally as hacks. Many websites provide instructions for different models of standalone DVD players, to hack, and their factory codes.

Computer DVD drives

Older DVD drives use RPC-1 ("Regional Playback Control") firmware, which means the drive allows DVDs from any region to play. Newer drives use RPC-2 firmware, which enforces the DVD region coding at the hardware level. These drives can often be reflashed or hacked with RPC-1 firmware, effectively making the drive region-free. This may void the drive warranty.

In most computer drives, users are allowed to change the region code up to five times. However, if the number of allowances reaches zero, the region last used will be permanent even if the drive is transferred to another computer. This limit is built into the drive's controller software, called firmware. Resetting the firmware count can be done with first- or third-party software tools, or by reflashing (see above) to RPC-1 firmware.

Since some software does not work correctly with RPC-1 drives, there is also the option of reflashing the drive with a so-called auto-reset firmware. This firmware appears as RPC-2 firmware to software, but will reset the region changes counter whenever power is cycled, reverting to the state of a drive that has never had its region code changed.

(UOps).

In common region-locked DVDs (but not in RCE-DVDs), the region code is stored in the file "VIDEO_TS.IFO" (table "VMGM_MAT"), byte offsets 34 and 35. The eight regions each correspond to a value which is a power of 2: Region 1 corresponds to 1 (2⁰), Region 2 to 2 (2¹), Region 3 to 4 (2²), and so on through Region 8, which corresponds to 128 (2⁷). The values of each region that the disc is not encoded for are added together to give the value in the file. For example, a disc that is encoded for Region 1 but not Regions 2–8 will have the value 2+4+8+16+32+64+128=254. A disc encoded for Regions 1, 2 and 4 will have the value 4+16+32+64+128=244. A region-free or RCE-protected DVD will carry the value zero, since no regions are excluded.
