Microsoft Longhorn To Support HD DVD Format 265
MSDVD writes "Microsoft's Japanese Division reported that its upcoming operating system, code-named Longhorn, will support HD DVD format. HD DVD is an enhanced version of the standard DVD technology. According to online reports, Microsoft is pushing the next-generation blue-laser DVD technology like NEC and Toshiba. Blue-light technology can read and write data much faster and at higher densities, which is needed for high-definition content. Few Japanese companies said they will have HD DVD content based DVDs by next year to support the players."

Microsoft likes HD-DVD because it uses their hacked up MPEG-4 CODEC. Microsoft "supporting" it in Longhorn doesn't mean much as both formats are supposed to start shipping years before Longhorn exists (2005). No doubt any PC drive manufacturers will have to write their own drivers.
The rest of the industry likes Blu-Ray because it has a higher storage capacity (54 GB vs. 30 GB), uses MPEG-2 so movie/television companies don't need to re-encode their HDTV streams and has Sony behind it (movie studio/music label).

That is, store only the difference between frames. Do this by spliting it into a series of blocks, and examining each block.
The devil is, as they say, in the details. I admit I'm fuzzy on a number of them, but this should be a respectable overview.
MPEG-2 uses a straightforward system of frames and partial frames (I frames, or key frames in DivX terms), and B and P frames (the two types of partial frames).
MPEG-4 adds a longer group of pictures (more P frames between I frames), additional encoding formats, and motion compensation. That last is the biggie - it means that if you're panning side to side, you just tell the codec to move the block a bit, and then give it the other bits. As compared to having to give it the scene shifted half a block.
MPEG-4 is also much more complex. I belive that any MPEG-1 or MPEG-2 bitstream is a valid MPEG-4 bitstream (or at least, is with a simple header rewrite). MPEG-4 has various additional bits, such as motioncompensation allowed to go out of frame, 1/4 pixel motion comp, B frames, variable sized motion comp blocks, mutlipe frame motion comp and other goodies. I don't think there is an actual codec that supports all of that lot, never mind the rest of the optional parts of the spec yet. That's why there are multiple MPEG-4 codecs - each can use a differnt goodie bag to try to be better than the others.
Other differences are the audio layers used. AAC is part of MPEG-4, in the same way that MP3 was part of MPEG-1.
As far as the best format for a disc goes - neither. In principle, the additional flexability of MPEG-4 should result in better picture / sound for same disk space. In practice, it's all perceptual anyway, so they turn the quality down until someone notices artifacts, and then nudge it up a touch. Sometimes, one might be better, other times the other, but as there is a human tweaking knobs at the backend, you can't tell in advance.

Wrong. (Score:5, Informative)
As explained [cdr-info.com] the main difference is that BluRay places the recording layer 0.1 mm below the surface of the media to maximize data capacity at around 27gb for single and 54 gb for dual layer. This will require disc manufacturers to build new factories because this is completely different from DVD and CD specifications. Because of this the layer of protective plastic will be very thin which some have speculated will initially require either a special layer of protective plastic which has been reported to decrease reliability or it will require the discs to be contained in a cartridge (think magneto-optical [storagebysony.com]). Carts would, of course, increase production costs and REALLY increase end user costs.
HD DVD places the recording layer at 0.6mm below the surface which is currently the standard used by DVD so that DVD manufacturing plants can make either format discs on the same assembly lines. This is at a cost, though, with a reduced capacity at 15gb for single layer and 30 gb for dual layer. And, of course, the existing protective layer will be sufficient as it is the same as the standard DVD.
The actual codecs supported will be the same for both formats. Both will support MPEG-2, MPEG-4, and (probably) Microsoft's WM9 codecs. As part of Microsoft's deal to get WM9 included in the HD DVD spec it was forced to open the specification to allow competitors to make products for encoding and decoding. Their benefit will be a share of the royalties for products that encode or decode HD-DVD content and sales of encoding/decoding software that they produce, but the deal does not include in any way a monopoly on encoder/decoder software.
The main difference, as stated, is the distance for the recording layer from the surface of the media which changes the maximal capacity because of the effect on the intensity of the laser as it passes through the media.

The "gift" is based on technology being developed by a consortium that includes IBM, Microsoft, Intel, Sony, Toshiba, Matsushita, Warner Bros. and Disney, and is being labeled Advanced Access Content System (AACS). Trying the usual PR stunt of passing a consumer right, upheld by most Worldwide copyright laws that for a long time have entitled consumers to private copy (something that has up to now, and as you will see, in the future, been denied), as their "gift" to society, they have just, as usual, forgot to mention some "little details".
The same industry that brought us region encoding, supposedly to avoid the possibility of buying a movie in a given place before it premieres at the cinema, although it is available elsewhere, in practice a cover-up to allow regional pricing of DVD (what else justifies 20, 30, 40 year old movies being region encoded?), has "forgot" to stress that this "feature" will only be available on the upcoming new-generation DVD format, still being cooked up by the DVD Forum, former DVD Consortium. So, to keep it short, they want us to buy all over again our DVD collection, now in a neat DRM crippled format.
After failing miserably with the CSS content encryption of current DVD, quickly cracked by the uber-reverse-engineer DVD Jon, and being at the present time little more than a nuisance, they want to have another go. But this time they are making their homework. Lets take the steps and see.
A little more than one year ago, Microsoft unveiled [slashdot.org] its plans for a new DRM system, nicknamed Janus. One year later [com.com] it is confirmed and Microsoft lets out a few more details on the features, licensing and partners. A few weeks later, the DVD Forum announces [com.com] it is going to include Microsoft WM9 codec in its upcoming HD-DVD specification (as a mandatory requirement). Although it may seem they are going down the same road and bound again to be reverse-engineered and fail miserably all over again, things are now different: of course Microsoft is going to patent its DRM scheme. So, while CSS was qualified as a "trade secret", not allowing the ones who cracked it to be prosecuted, reverse-engineering Microsoft DRM scheme will be violating patent law, and the all-mighty DMCA, what makes it a completely different scenario.
Microsoft has already shown it is very interested in the media turf. After developing its own audio and video codecs and using its dominating position to spread them to the web and hardware devices like portable players and even some standalone players, and after including its Media Player in all current Windows version (earning them the current EU law suit), that will of course support both the WM9 codec and the Janus DRM, we can already see they are trying to broaden their scope. This can be seen on their Windows XP Media Center Edition 2004 [microsoft.com], and it would not surprise me to see it ported to standalone devices, either on its current packaging or by porting it to Windows CE.
