She has been with you that the British TV series DVD that you have been for centuries after. Now you're at home, the United States. You are waiting to put in your DVD player and watch the series. There is something wrong! All you can see the display "Wrong Region" or words to that effect. You are very surprised to see. And the DVD player not working? Or is defective DVD? What is it? The box where the DVD came and saidThe disc is Region Free, which means that it is intended for Region 0 or All Region. Is not it mean that the DVD will play in the world? Well, good news is that there is something wrong with the DVD-ROM or DVD. Id The bad news that the wonderful world of DVD region coding region lock or sometimes experienced as you call it. You're asking me what is DVD Region Coding and why is it necessary?

A Free Region, Region FreeZero or Region All regions of the disc should be played on a player Region Locked, but there is the problem of compatibility between PAL and NTSC. For example, suppose you have a Region Free DVD received from the United Kingdom and try to play in an American NTSC players. The DVD will not play because the disc is in PAL video format. There is a misconception that because the DVD is based on a digital format, it matters less if your player plays NTSC or PAL. All digital video formats is basedIn either PAL or NTSC video systems.

But what is PAL and NTSC video systems? Let me briefly explain.

Countries around the world, use one of the three major TV broadcast standards. These three principles – NTSC, PAL and SECAM not. But these three rules are incomplete with others. Consider the region free DVD that was purchased in the United Kingdom. It did not play correctly on a U.S. NTSC DVD player because the DVD is in PAL video format. This misunderstandingI have somewhere in my discussion above, contains no good, and like I said, all digital video formats, including DVD are still based on PAL or NTSC video systems.

Let me briefly outline the PAL and NTSC for a better understanding.

The first broadcast in color arrived in the United States in 1953. It is based NTSC – National Television Standard Committee System. NTSC is used by many countries in the Americas and Asia and in countriesincluding Japan. NTSC runs on 525 lines per frame.

Phase Alternating Line (PAL) system was launched early in 1960 and is available in most European countries except France. PAL uses a bandwidth greater than NTSC-Chanel, which is a better image. This system operates at 625 lines per frame.

Sequential Couleur Avec Memoirs or sequential color with memory (SECAM), standard in 1960 and was introduced in France performed. SECAM transmit color informationsequential, but uses the same bandwidth as PAL. Standard runs on 625 lines per frame.

For a better understanding of the following is offered:

Corresponding to a multi-VCRs, DVD players can not video standards. A DVD player will accept a PAL DVD disc is not formatted in SECAM.

There is a point to consider if your end in despair. If you have a multi-TV that is capableto receive both PAL and NTSC signals, you can probably see that the DVD you have from the United Kingdom. You can also use a converter that would allow a PAL to NTSC and vice versa. This way you can see that the DVD from England, played on a standard TV NTSC converter of all that for you. You can buy a region free DVD player that also has a multi-region DVD player or a code free DVD player, which is known with a built-in video standardsconverter.

The so-called regions, which feels so much about when you buy a DVD or a player is catagorised follows:

1. Region 1 – The United States and Canada

2. Region 2 – Europe, Japan, Middle East, Egypt, South Africa, Greenland

3. Region 3 – Taiwan, Korea, Philippines, Indonesia, Hong Kong

4. Region 4 – Mexico, South America, Central America, Australia, New Zealand, Pacific Islands, Caribbean

5. Region 5 – Russia (okay, former Russia), Eastern Europe, India, most of Africa, North Korea, Mongolia

6. Region 6 – China

Traditionally, statistics say that people will see the first Region 1 DVD. Region 2 will have to wait 6 months, and Region 3 staff will be a year to download their favorite movies on DVD to watch.

DVD set, home entertainment to life. DVD players and movies soldhot cakes around the world, as prices tumble for both products. The concept of Home Theater has a higher quality of audio-visual equipment offered by DVD. Entire rooms in many houses kept confidential for the home .. But with the success of a DVD being dirty little secret: region coding region of the lock.

Why this code, you can find out more. Well, we were told that is the way they want to protectCopyright. Another aspect of the region encoding the surface recently. It is perhaps because of the price of confirmation of the various regions of the DVD.

According to many times, is a violation of the Code of maintenance in the WTO free trade agreement, reflecting the competition. The Australian Competition and Consumer Commission has seriously considered this encoding and warned that this code may violate the Trade Practices Act A similar declaration was made by the Government of New –Zealand. So basically, the DVD players sold in their countries, Region 0 Region 0 DVD players are required to take 1-6 region simultaneously, which means your ability to drive an apartment, regardless of which area they should.
