The Benefits Of The Blu Ray Disc



The benefits of​ the Blu-ray disc.
this​ article will give you​ an​ overview of​ the benefits that the next-gen blu-ray format will offer over conventional formats such as​ DVD.
The blu-ray format is​ going to​ push forward the limits of​ current media substantially which allow you​ to​ enjoy a​ host of​ great benefits which include:
• Improved Capacity,
• High-Definition​ Video,
• Enhanced Interactivity,
• Enhanced Copy Protection, and​
• Being Future Proof​ .​
The most obvious benefit is​ the larger capacity .​
With 25gb/50gb to​ use, movie and​ game studio's will be able to​ offer much more in​ terms of​ extra features and​ longer gameplay .​
Also many new DVD titles require 2 discs for​ added features whereas only one will be needed for​ blu-ray which will lower the prices for​ you.
High-Definition​ (HD) video playback is​ perhaps the most useful aspect of​ the next-gen formats .​
As HD becomes more mainstream (Sky launched there HD offering recently and​ more households are buying HD ready TV's) the ability for​ disc formats to​ support it​ is​ imperative .​
Blu-ray offers space for​ 2hrs/4hrs respectively of​ HD video (different encodings will allow more and​ less) with space for​ interactive features still available .​
The enhanced interactivity features are another step forward compared to​ DVD .​
By incorporating the java platform (called BD-J), blu-ray players can have dynamically changing interactive menu's that can be updated via an​ internet connection​ built into the player .​
These updates can include extra subtitles tracks and​ promotional features not available at​ purchase .​
this​ could effectively eliminate the 'special editions' studios tend to​ use as​ users could simply download all the extra features they wanted though its not clear if​ this​ will be free.
The enhanced copy protection​ is​ one aspect you​ won't notice as​ much but is​ very important .​
Blu-ray utilizes a​ variety of​ copy protection​ methods such as​ Digital Rights Management (DRM) and​ Advanced Access Content System (AACS) .​
The DRM method used on​ Blu-ray is​ called BD+ which creates dynamically changing keys to​ protect the discs .​
this​ means that if​ a​ key is​ cracked only a​ select portion​ of​ the discs are compromised .​
The AACS can effectively disable players which are deemed 'bad' .​
i.e .​
if​ copied discs are used frequently, the AACS could disable the player for​ the user and​ stop it​ working even if​ bought by someone else .​
The final copy protection​ which may affect you​ is​ the Mandatory Managed Copy System (MMCS) which limits users to​ a​ set number of​ copies of​ discs by making the user register the 'right' to​ copy the disc.
Finally the blu-ray disc has been designed to​ be future proof​ .​
this​ means that by buying all the new equipment needed, you​ will not need an​ upgrade in​ the near future (5 yrs) as​ these next-gen formats evolve .​
Also TDK has announced work on​ a​ 200gb blu-ray disc (6 x 33gb layers) which will future proof​ the format even more.
this​ is​ just an​ overview of​ the benefits that blu-ray offers .​
There are many smaller improvements but the benefits listed above are the ones that you​ are most likely going to​ affect you.
