The existing purpose of blu-ray and HD-DVD is to have as a lot public support rapidly as in the long run it will be the customer who will decide which format arrives on top. With the unification talks failing it really is under your control to make the selection of which format to adopt. To assist an individual with this hard selection is the lowdown on just how each and every format matches below.
History
The blu-ray format's head manufacturers are Sony and Philips with Toshiba as well as Hitachi going up the HD-DVD format. This scenario is not the first time when these two sides have gone at each other with opposing formats. The DVD format came to be through the cooperation of the Multimedia Compact Disc by Sony/Philips (MMCD) as well as the Super Density Disc (SD) coming from Toshiba. Although it ended well to the consumer with the DVD format being broadly adopted as well as being the newest standard, it was Toshiba's camp that came out top most in regards to royalties.
This led to the work on modern formats by either sides with Sony planning to take back a number of its lost market. The two projects though had been in production though not really heading anywhere at the moment. Sony's Professional Disc for Data (PDD) became the blu-ray format while Toshiba's Advanced Optical Disc starting to be HD-DVD. This leads us back to the original situation wherever you will find two competing formats with a unification looking a lot less likely.
Technical
Together blu-ray and HD-DVD use a wavelength of 405nm however the smaller track pitch on blu-ray (see Blu-ray Disc) makes it possible for a lot more information to become squeezed on as well as gives the larger capacity. However it may be the differing track pitch that makes these two formats incompatible. The surface layer of the 2 is various also as HD-DVD utilizes a .6mm layer like DVD while blu-ray uses a .1mm clear plastic layer.
This kind of difference may be the main reason prices are greater with blu-ray. Expensive production methods are needed to be able to make the discs and also a hard coating must be applied to create the discs suitably resilient to dust and fingerprints.
Capacity
Blu-ray right now provides discs in 25gb for single layer and 50gb for dual layer. On the other hand TDK has began work on a 200gb disc that is 6x33gb layers.
HD-DVD is available in 15gb for the single layer as well as 30gb to the dual layer. Best tests so far have attained 45gb although 60gb could be the theoretical limit. This illustrates that the maximum for HD-DVD is merely 10gb a lot more than what blu-ray can already offer.
Codecs
Each formats use similar codecs to play video as they are both equally able to play standard and high-definition. Which means MPEG-2, Microsoft Video Codec 1 (aka VC1, WMV HD, etc.) as well as H.264 / MPEG-4 AVC are all supported on together formats.
Security
Together blu-ray and also HD-DVD have to make use of HDCP encrypted output as well as the Advanced Access Content Technique (AACS). Equally HDCP and also AACS are mandatory for any discs with HD video.
Blu-ray furthermore comes with ROM-Mark watermarking technology and also BD dynamic crypto that creates special keys for batches of discs.
HD-DVD uses the same technique in the Volume Identifying technology.
Support
Together formats are heavily supported in equally the Consumer Electronics (CE) and also Facts Technology (IT) industries. Nonetheless blu-ray has a better portion of the big name movie and also game studios supporting it that is essential for there to become a ready amount of content at launch. See below for that list of Supporting studios: Blu-ray: 20th Century Fox, Buena Vista House Entertainment, Electronic Arts, MGM Studios, Paramount Pictures, Sony Pictures Entertainment, The Walt Disney Company, Vivendi Universal Games, Warner Bros.
