The difference between an ordinary and high definition DVD player
It is not only the fact that a high definition DVD player provides us with the combination of very high quality audio and video. It also provides us with the ability to play the latest DVDs from any region of the world. A costly and good quality DVD player that is not region free or high definition can also provide quality audio and video. But the performance of such equipment is restricted in the sense that it can only play DVDs from that particular region, with that region standard built-in. The standard video resolution can be at best 480 visible lines of details. On the other hand a high definition DVD player enables you to view 1080 visible lines providing a greater detail of a picture or image. When it is a region free DVD player, it can play any DVD from any part of the world, with precision, on your TV, that might not be originally compatible with the standard of the DVD. Therefore, the differences are, that an ordinary DVD player will allow you visualise up-to 480 lines while a high definition, with its 1080 lines, provides a better picture clarity. The High definition DVD player also comes in two categories; one is of 720 pixels while the other is of 1080 pixels. Thus resolution and quality wise, there is quite a big difference between an ordinary DVD player and a high definition DVD player.
The High definition region free DVD player
Now we come to the object of our study, the high definition region free DVD player. After having a brief overview of the ordinary and high definition DVD player and their basic differences, we now move on to the term 'region free'. A region free DVD player is one that can play DVD of any standard to be viewed on your TV without going for the compatibility equipments. DVDs cannot be played on all players. Different regions in the world use different standards for a DVD, like PAL, NSTC, and SECAM, as used in Asia, Europe and North America, except that France with few of its neighbouring countries, use SECAM. A region free DVD player will play all types of DVD irrespective of whatever standard they might follow, which solves your problem of not being able to play a DVD of a different standard.
Generally, three standards are followed all over the world in case of DVDs. These are PAL standard, that are used in most part of Asia, Europe and Africa; the NSTC standard used in North America and major part of United States; and SECAM standard, followed in France and few other European countries and Middle East. The problem with these standards is that they are not compatible to each other. As a result, a DVD procured from Europe or Asia, is not compatible with your NSTC compatible TVs used in America. Similarly, the NSTC compatible DVDs from the United States cannot be played in most part of Europe and Asia since they use PAL compatible TVs. The same principle is applied to playing SECAM, the oldest of the standards, on non-compatible TVs elsewhere. A region free DVD player solves these problems by allowing you to view DVD with any standard on any type of TV with its inbuilt system of conversion to compatible standards.

Basic elements of a region free high definition DVD player
Now we may have a basic reference to the technicalities involved in a high definition region free DVD player. A region free DVD player is one, in which the manufacturer has not used the region based lock system. Ordinarily, the video game DVDs are always made free from region locking, because they are used universally. But other types of DVDs, especially movie DVDs, have the regional locks, which mean that DVDs of a particular zone will not be play in another zone. The high definition region free DVD players overcome these problems using a unique unlocking mechanism.
Internet and World Wide Web plays an important part here too, since a whole database of DVD unlock codes are available at the DVD code unlock website. In technical terms, a HD DVD or High Definition DVD is a optical disc fromat that can store both high definition video and audio data. In fact it is an expansion of the DVD optical disc format. Instead of the blue violet laser with 405 nm used by a standard DVD, a HD DVD uses a 650 nm wavelength red laser. Therefore, a high definition region free DVD player is an affordable alternative to the price of blue laser optical devices. One basic advantage of the high definition DVD player is its superior image display capability. The high definition region free DVD player is gradually gaining popularity and most of the leading companies in the business have come out with their respective models. Sony, Panasonic, Toshiba, Phillips, Sharp, Samsung, and NeuNeo are some of the leading companies producing high defintion region free DVD players.
Why buy a high definition region free DVD player
With the improvement in audio-video technology, almost all new TVs are high definition ready and compatible. If you do not have a high definition DVD player or not upgrade the existing one, it means you are not using your TV to its full potential. A high definition DVD player will provide you with 720, 768, and 1080i pixel resolutions. However, while purchasing a code free or region free high definition DVD player you must be careful of two things. First you must ensure that it provides a life time guarantee. Second, you should also opt for equipment with at least an 8 MB video converter that is good for any TV upto 27" size to give good picture quality. For larger TVs you may use 14 MB video converter. Once these aspects are taken care of, along-with the feature future up-gradations, you have a deserving equipment.
