In these areas, region coding is effectively leveraged to censor content that is considered to be unethical, improper, or undesirable. This is explained below to provide you with an accurate understanding. In total, there are 3 separate Blu-Ray region codes.
Blu-ray discs that have been manufactured in region A are embedded with region code A, and are therefore only usable with players from region A. The same is applicable for regions B and C. Below is a map showing how Blu-ray region codes are separated and administered by geographic location. Guide map of Blu-ray region codes.
This map shows the different Blu-ray codes and which areas they are utilized in. Click the map to view in full-size. There are 6 individual region codes with which DVDs are embedded.
These 6 region codes function in the same way as Blu-ray region codes. The rationale was that if too many Europeans bought the North American version, this would cut into sales of the European versions. For example, as of this writing the film Syriana Warner Bros.
Whatever the real reason for the introduction of region codes, there is no technical reason why they are necessary: From the perspective of people who want to watch DVDs from other parts of the world, region codes are merely an artificial obstacle that needs to be overcome.
However, this presents certain challenges. Fortunately, some manufacturers produce equipment that will run on either type of current.
It is also necessary to have a plug adapter, since the electrical outlets and plugs used in many foreign countries are different from those in North American. Such plug adapters are easy to find and inexpensive. However, there is another obstacle that is not so obvious and that is more difficult to overcome, namely video encoding standards see below.
These are hard to find in retail stores, but can be found on eBay. Notice that it has a North American power plug, so it is not even necessary to get a plug adapter:. I do not know how the features and price of this DVD player compare with those of comparable players, nor am I certain that every DVD player bearing this model number is region-free, so I am not recommending this one over other brands.
If you choose to purchase such a piece of equipment, you yourself should check the different models that are available, what features they offer, how much they cost, etc. However, apart from the question of brand, price, etc. It is also more straightforward to use, since it can definitely use North American electrical current and does not even require a plug adapter. Moreover, such players typically can also output signals encoded using different video encoding standards see below.
Some such players are supposed to be able to recognize what video encoding is expected and automatically switch over; however, whether this is switch-over is automatic or needs to be done manually is not very important, because it only needs to be done when the player is first connected to the display equipment television set , which is usually only done once.
Video signals can be encoded according to different video encoding standards. The details about these standards are beyond the scope of this article. Suffice it to say that video encoding standards are a true property of the video signal and have to do with the type of equipment that produces the signal: They do not represent an artificial obstacle as DVD region codes do.
Here is a map showing where the various video encoding standards are used. Although some newer television sets may be able to accept video signals in different video encodings, the typical television set currently being used in North America accepts only NTSC signals. If such a television set is connected to a piece of video equipment that outputs a PAL signal, the sound will be normal, but the picture will be in black and white instead of color, and it will "roll", as if the vertical hold were badly out of adjustment:.
One obvious, although expensive, way to overcome the video encoding problem is to purchase not only a DVD player but also a television set to display the video signal produced by the DVD player.
