Just read this article and know most interesting and most important facts about this amazing disc! Intro. 'Blu Ray' name comes from the colour of the laser that reads and writes this type of disc - blu laser. Because the wavelength of this laser is shorter than the red one, which is used to DVD format, more data can be stored at the Blu Ray DISC. Consumer got to know this kind of disc in 2006 but it was known earlier as a format od programs released in the TV. In short time Blu Ray won a war with HD DVD format. Compatibility. As it was said, at first Blu Ray appeared to the world as a format of TV programs, films. Those specifications were defined in 2003. Blu-ray Disc ROM format specification was defined in 2004.

Blu-ray discs are here to supersede DVD in every way, be it quality of picture (1080p), interactivity (BD-J), size (50Gb) and now protection. CSS Conventionally the DVD used CSS (content scrambling system) as its encryption, although mediocre, the development of a new encryption would have been time consuming and would have caused delays. Hackers decrypted the system in little time inducing a loss of billions. The main decryption known today is DeCSS created by Jon Lech Johanssen (alias DVD jon), who proclaims in his defense that he simply wanted to back up his own collection of legally purchased DVD. Blu-ray Initially Blu-ray was introduced by Sony as a larger recording media for back up purposes but as there was demand for high definition movies that required high capacity media, the amalgamation of the two was inevitable. Having learned from the mistakes of CSS a better encryption method was needed. AACS AACS (advanced access content system) jointly developed by Sony, Toshiba, Warner, Panasonic, IBM, Microsoft and Intel will be used with both HD-DVD and Blu-ray. This system can stop a device from playing any more movies causing it to be useless. This is done if the machine is hacked to perform an illegal rip. What AACS can do is disable the decryption keys unique to that device. AACS also incorporates an image constrain token (ICT); this applies to analogue video outputs downgrading the HD video signal to a maximum resolution of 960 x 540. ICT is only an option for the video content owner. An audio watermark is another feature of AACS again being optional to the video content owner which is an inaudible signal inserted into the audio track. ROM-MARK In addition to AACS the Blu-ray association have decided to add another two layers to the BD-ROM the ROM-Mark and the BD+. The latter is something we will discuss later. The ROM-mark is another layer added to the protection of the disc from pirates. It is an analogue level mechanism of bit-by-bit copy protection and will be embedded in pre-recorded ROM media such as movies, music and games. The ROM-mark is invisible to the consumer and requires special Blu-ray manufacturing equipment to be created. BD+ BD+ is a variant of a technology called self-protecting digital content (SPDC). This provides dynamic renewable protection. Title specific code is extracted from the disc and embedded into a virtual machine, security software checks are done by the disc to secure its own playback. Inevitably what this does is allows video content providers to renew content protection on BD-ROM players which have been hacked. Conclusion The future of Blu-ray protection is important and imperative in an age of hackers. Their philosophy at getting back at the big movie corporations and their rip-off to consumers not surprisingly has the majority vote with people who want to pay less. Whether this protection will suffice in this day and age is difficult, we must remember that hackers have a lot of time and resources to achieve their goal; however this time round the developers of Blu-ray protection have been working on a better time schedule to come up with something water tight. Unfortunately I believe it will only be within a year before some technique is found to copy Blu-ray movies as very feasible ideas have already been posted on the internet.

With the Blu-ray format becoming more and more popular, there are now many different versions of Blu-ray DVD Players in the marketplace, all having their own set of features and functions. Combine this with the fact Blu-ray is a relatively new technology, it can get a little confusing for us consumers to figure out exactly what to look for when buying a new Blu-ray player. To help you decide, here are four features every good Blu-ray DVD Player should have: BD LIVE All Blu-ray Players are divided into Profiles and each Profile offers certain functions and features. Older profiles are 1.0, 1.1, 2.0 and BD-Live is the latest and newest Profile. It is the best profile and contains all the functions and features of 1.0 and 1.1, as well as a few new ones. Most Blu-ray Players manufactured today are Profile 2.0 or BD Live, but not all of them. BD-Live allows you to access a wide variety of bonus material found on the web, such as online movie related games, latest trailers and other content. It allows your movie experience to be interactive since you can go into chat rooms and discuss movies online. Ethernet/Wireless Blu-ray Players are not sorely about the Blu-ray disc anymore, it offers so much more. Being able to connect your Blu-ray Player to the Internet or your home computer is no longer a convenient perk but a definite must. In the beginning the Ethernet port was mainly used as a nice and fast way of upgrading your Blu-ray Player's firmware. Although this is still the case, having your Blu-ray Player connected, now offers so much more. There are many services out there that have online streaming of movies and TV shows in High Definition. Services like Hulu, Netflix and Amazon-on-Demand offer a wide variety of movies and TV shows in HD. Therefore, you no longer have to pay for specialty HD cable channels in order to watch your favorite TV shows or movies; you can Stream them online for free. The Blu-ray DVD Player having a wireless connection is big plus since you don't have to deal with all those annoying cables. Blu-ray Players with wireless Ethernet, once you turn the power on, will automatically pick up your wireless home network and connect you to it. Streaming movies and pictures from your home computer is also something you can do via some Blu-ray Players. Fast Load Times Blu-ray DVD Players have a reputation of very slow disc loading times. In the past, and to some extent still today, this has been a main criticism of Blu-ray DVD Players. It may seem like an insignificant feature, but most people when they insert a disc want instant playback and waiting around for a few minutes before you can access your disc can get rather annoying. Adding to the annoyance is you get different loading times with each movie Blu-ray disc. The good news is that Blu-ray Players are improving their load times. Players like Sony's PlayStation 3, OPPO's BDP-83, and Samsung's BD-P3600 have very fast loading times, and most Blu-ray movies have the exact same loading time. Remember, updating the Blu-ray Players firmware can increase loading times, as manufactures are always trying to improve playback. Audio/Video Lastly, but certainly not least, it should come as no surprise that a Blu-ray Player should have great audio and video. Having a clear, sharp, crisp image/sound is a very important feature and Blu-ray Players can deliver this if they have Full HD 1080p video output. Every Blu-ray Player will have Dolby Digital, DTS, and PCM audio formats. However, if you want the best, Dolby Digital Plus, Dolby TrueHD, DTS-HD High Resolution and DTS-HD Master Audio; these are the formats you should look for in a Blu-ray DVD Player. These will bring you the best possible sound and most blu-ray movies will be encoded with these audio formats. Of course, there are other great features and functions that a Blu-ray Player might have, but these four features are the core basics to every good Blu-ray DVD Player. Having all four of these features will make for a solid, dependable Blu-ray DVD Player, fully allowing you to get the best enjoyment out of your movie viewing experience and even a little bit more.
