Becomes quite complicated when you try to describe the differences between systems and transmission systems for video, so stick with which video systems found in VCRs, camcorders, DVD and Blu-Ray, etc.
These are the basic standards and none are compatible with each other. Sometimes the A / C Hertz are 50 MHz (220-volt countries) and, sometimes, 60MHz (110-volt countries) and that changes the results of the scan of an electron tube or plasma, etc. LVD 60MHz, used in the U.S.This is the most soft, almost no flicker. With the double line and quad-double (100 and 220 MHz and then 200 and 440 MHz).
Line doubling actually linked the image in a single scan, which shows the entire structure and doubling again increases the scan lines to provide a finer resolution and there a better feeling for the reality to the human eye. Technically, the original structure with two fields and creates a progressive scan (single non-interlacedFrame) output. This produces a high resolution image is bright and smooth.
1365x1024, 720p, 1080i, 852x480, 1024x1024, 1024x768 and 1365x768 and above: some third party-line quadruples can can scale resolutions. If the latest technology in video images of the world will see hit, NHK pictures today of more than 6000 lines, from which a maximum of 1080p.
If you quadruple-line image like the one that reaches the mind can not know when it is connected to startdirectly into the motherboard of the future. Perhaps an expansion and improvement of human vision are needed in the order of 1,000 eyes, 360-degree views of both sides in the longitudinal direction and 100 million lines of resolution so far surpassed all human capacity today.
Go to PAL-NTSC for a moment.
These video systems for many because of incompatible standards, such as the electric Hertz, because of economic and even political reasons (for example, have been created, a country has notyour TV from another country, citizens are seen nearby, so they are not "ideas" to get!
With the advent of the DVD producers in Hollywood have decided to exploit the latest advances of electronic technology in this new step forward to better market their films.
For films released in the VHS versions, but in 5-6 different non-competition systems and the release of films around the world could be staggered as very useful for the best marketing practices to rakepossible from each country. A film in April, published in the United States had until the right time in South America and the idea of man in Argentina (PAL-N) was able to buy the film from an American retailer released a plan nearly useless when the 'Argentina will not have no TV and VCR to play the right system and with the images. NTSC and PAL-N, displayed properly on systems not only wrong, the speed of recording and reproduction are different. This means an NTSCTo see a movie on a PAL or other standards usually in black and white to have terrible problems of vertical scrolling, horizontal have a slope to the top of the image and the speed was wrong, so the voices too fast or too slow were . It 'a mess!
Until the Japanese VCR (and Sony BETA) leaders came up with multi-system VCR!
Most could only play tapes of different standards, but to see them you need a TV that was good TV or multi system 2, oreven three of each respective system, that you were out of the VCR.
To remedy this, that the purchase was a multi-system TV Panasonic AG-W1 model with unbelievable that play an integrated digital converters, may absorb and convert to / from all over the world, five current systems. Was $ 4,000, but it was a great device excellent results, though not for broadcasting purposes.
Many people who buy the AGW-1 (and later their descendants WEL-2 andAGW-3 through the purchase of a Digital Planet Omni Tenlab converter systems for a fraction of the cost of AGW-1 and the use of a multi-system VCR.) In this way, the image quality is the same or better and when the price to the consumer.
Soon came with the much cheaper AIWA MX-1 converting multisystem VCR, not a digital type, but use the analog conversion methods are much worse, then Samsung, GoVideo and a few others. Samsung was the actual PanasonicWEL-1 and 2 and under its own brand, have come up with a variety of models such as the SV-3000W, SV 5000S, SV-7000W (with the only French SECAM-L tuner built in).
Planet Omni has some of the Panasonic, Aiwa and Samsung for sale. No one has for 2-3 years and the death of the VCR will never be produced again made. People all over the world with old movies should check whether you can burn them to DVD, the converters are also from PAL to NTSC or NTSCPAL. All countries with any system, but the two find that their tapes can be converted to PAL, and is a perfect display on television, even if the TV is not necessarily PAL.
People can use in a surface-to-NTSC conversion services, such as Planet Omni tapes or DVDs and convert PAL to NTSC or vice versa, rather than buying PAL-NTSC-DVD (it does) and a converter TENLAB.
Because Hollywood producers were OK with the world's most incompatible VHS video standardIt 'was a new problem with DVD movies.
Since all PAL SECAM countries are also countries as far as their televisions will go multi-system and the same for PAL-M (Brazil) and PAL-N (Argentina, Paraguay and Uruguay) countries, this means that the film DVD just yet either NTSC or PAL to be and could be seen all over the world.
That was not very good for Hollywood directors, though, because too many countries could buy the discs from another country and watch movies directly from their first release on CDsometimes anticipated official release films in cinemas. This meant that a citizen of a country like Italy, PAL was able to buy a new film from New Zealand (PAL) source and see the film (with subtitles if necessary), perhaps months, before the film was actually released in theaters or on DVD in Italy. This violates the natural markets of established theater owners and retailers in Italy.
In general, if a European country is a film on DVD, evenat the same time in other euro area countries, but not always. But then a person speaking English in Australia could buy the film from a source in English on the English and it's PAL TV.
Not very good for business and bean counters.
So a new technology in every Hollywood film from various countries around the world sent embedded. This is called the region code.
They divided the world as best they could in six regions on the release filmProtocols.
These regional codes are integrated both the DVD player and DVD-Video discs.
6 regions, 2 video standard (PAL-NTSC), things pretty complicated.
For example, Europe is PAL and Region 2, but Japan is NTSC REGION 2 yet!
This means that Japan would play a DVD player on a Japanese DVD, but well, even if it is REGION 2, should not have to play a European PAL TV, even if you have the Japanese DVD players in Europe, has raised the voltage of 100Vto 240 and then tried to play it. The disc should run, the player could play, but the TV can not show ... unless the TV was also a multi-NTSC TV.
So how do you get these video standards and regional codes?
The invention of the REGION FREE DVD player (also known as free code, code free, zone free, all zones, universal throughout the region, etc..) But this is against the law and how can you do? What does it mean?
It is permitted by a license agreement, no manufacturer of DVD playersa region free player. Everyone must be committed to a particular region. It can be either PAL or NTSC, but the region code should be specific to a region. The U.S. is Region 1 ... and here are all:
Region codes and countries
Region Code
0 informal term for "the whole world." Region 0 is not an official institution, the discs that bear the symbol 0 or the region have no flags or region 1-6 flags set.
1 Bermuda, Canada, Cayman Islands, United States of America and the United StatesAreas
2 of the European Union, Albania, Andorra, Bahrain, Bosnia-Herzegovina, Croatia, Egypt, Faroe Islands, French Guyana, Georgia, Greenland, Guernsey, Iceland, Iran, Iraq, Isle of Man, Israel, Japan, Jersey, Jordan, Kosovo, Kuwait, Lebanon, Lesotho, Liechtenstein, Macedonia, Moldova, Monaco, Montenegro, Norway, Oman, Qatar, San Marino, Saudi Arabia, Serbia, South Africa, Swaziland, Switzerland, Syria, Turkey, United Arab Emirates , the State of Vatican City, Yemen

7 Reserved for future use (found in use protected screener copies of MPAA-related DVDs and "media copies" of pre-releasesAsia)
8-seat organizations, such as airplanes, cruise ships, etc. [1]
All Regions All the discs are all 8 flags set so that the disc can be played on any player in any room.
All Regions All the discs are all 8 flags set so that the disc can be played on any player in any room.
So it's against the law to change and make a DVD CODE FREE?
No, not at all. PLANET OMNI sold many places as they have for years. The quality of the changerarely varies, usually is a perfect model so that each play DVD movies, but there will be a PAL-NTSC TV or a video converter to display both PAL and NTSC DVD movies.
Remember that a movie on DVD not a DVD-R or DVD + R, although it may have a movie that has been registered.
Most DVD players code free play most DVD-R and DVD-RW, DVD + R and DVD + RW discs are homemade.
99% also play regular music CDs for playback, and many others play a variety ofFormats like MP3, WMA, DVD-Video, Video CD, DVD-Audio, SACD, CD, audio CD-R and CD-RW, WMA, JPEG, JPEG and JPEG and Kodak.
Thus, a REGION FREE DVD players play all regions and both PAL and NTSC discs, which is any known type of DVD movies on earth, but if you do not have a standard TV PAL or NTSC video converter
Besides the fact that you can buy these items, but also CONVERTING DVD player region free.
Some may convert a DVD movie on NTSC and PAL can do a little 'that a disk drive and U.S. NTSC to PAL.
And some can do both, but if you ever get a PAL-NTSC TV you can turn off the conversion and see everything, all DVD movies from all countries in all the standards on any TV in the original image quality. Here too the online stores such as Planet Omni this type.
This free code, players can also use the conversion of the most modern equipment with the latest bells and whistles and certainly things such as stereo DTS, Dolby willDigital, HDMI and DVI output, 5.1 channel stereo and high-output, progressive scan and so on.
But now consider what this means in terms of Blu-Ray Multi-region.
Because HD DVD is dead as a Hi-Def format, whereas the Blu-Ray discs and movies on Blu-Ray to stay here until the next true leap into the future with us, perhaps around 2012 entry happen in the last line 6000 Super Hi-definition TV, and about 6 x Realistic 3Dappear as a Blu-Ray and 1080p technology.
As for Blu-Ray DVD players and, for each region, called Region A, B and C.
These regions are not compatible, PAL-SECAM-NTSC and other systems contain.
The beauty of a region A or B Blu-Ray, when in a multi-region Blu-ray Disc player via HDMI output (which is a single cable connects all audio and video) is played, the TV PAL should not be-SECAM-NTSC or anything specific at all. WhileTV has an HDMI input, all Blu-ray Disc from regions A and B will play in their full glory, and, probably, depending on the maximum resolution possible from any TV with the highest quality. PAL and NTSC is no longer present in the world HDMI, the problems of Hertz, government controls and so on, it Up!
However, there are still regions A, B and C.
For production companies in Hollywood these 3 regions are still important, but not as they once were.
They know thatBlu-ray Disc from the regular component, S-Video or composite (A / V RCA) or reimburse the appropriate standard for films with a vision, PAL for PAL and NTSC on NTSC discs disk. But there are no televisions in the regions as a PAL-NTSC TV is not PAL or NTSC DVDs can be viewed.
In the case of multi-region BDP-S300 Sony version now available (110 volt version) you can see in every Blu-ray Disc from countries A and B under the pop and on any TV with HDMI You can enter theEntirety of each library.
The BDP-S300 player Sony Multi-region with many reviews as already highlyrated: .. "I'm with my Sony BDP-S300 Blu-ray Disc, it looks excellent acoustics and visual definition of crystal clarity of 1080p Blu-ray Disc and DVD upscaling brings your DVDs with the highest possible resolution. The purchase of this product and will not be disappointed. "
The Blu-Ray regions as follows:
A North / America, Central AmericaAmerica, South America, Japan, Taiwan, North Korea, South Korea, Hong Kong and Southeast Asia.
W / Europe, Greenland, French territories, Middle East, Africa, Australia and New Zealand, and all of Oceania.
C / India, Bangladesh, Nepal, China, Pakistan, Russia, Central and South Asia.
The future of Blu-ray-type of technology?
In January 2007, a preview of Hitachi 100 GB Blu-ray Disc, which has four layers of 25GB each. Unlike TDK and Panasonic 100 GBRecords, says that this CD is readable on a Hitachi Blu-ray Disc player, a firmware update is the only requirement to make it readable to current players and drives.
Many iterations and variations of the Blu-Ray plunge new concepts of environment, such as BD9 / BD5 Blu-ray Disc, AVCREC, Blu-ray, HD DVD / Blu-ray Disc Hybrid HD VMD / Versatile Multilayer Disc (new low-profile entrant ) AVCHD, Digital Multilayer Disk - the successor technologyFluorescent Multilayer Disc, Enhanced Versatile Disc (EVD), Forward Versatile Disc (FVD) - standard with 200 and 300 GB of memory in the development of optical storage of 3D data - - Taiwan backed red laser format, Fluorescent Multilayer Disc Holographic Versatile Disc The next-generation technology should provide TB disk capacity, protein coated plate, Tapestry Media, Ultra Density Optical LS-R - a "layer selection" technology that allows storage of large number of DVD-like dataLayers on one disc, Professional Disc for Data (PDD and sewer) and much more.
Yes, there are still regions? Who knows, but it is always better to be a genius to overcome.
