Microsoft goes to Hollywood

That could mean disappointment for some of the tech industry's biggest names, particularly if other studios follow suit. Companies such as Microsoft and Apple Computer have been betting that their work on advanced video software formats, called "codecs," will help them sell their own products."
The lexicon of video technology often sounds like a foreign language. Here are a few key terms.
Codec A technology for squeezing audio or video into smaller packages for easier storage or transmission. The name is derived from a blend of either "coder-decoder" or "compressor-decompressor."
Moving Picture Experts Group (MPEG) An international industry organization that ratifies standards for audio and video technologies.
MPEG-2 A set of multimedia technologies finalized by the MPEG group in 1994. Typically used as shorthand for the video codec, finalized in 1994, that is used today on DVDs, cable networks and in many other places.
MPEG-4 AVC A later video standard finalized by the MPEG group. Also known as H.264 or Advanced Video Coding.
VC-1 The version of Microsoft's Windows Media 9 video codec submitted to industry standards bodies for use on DVDs and elsewhere. Was temporarily known as VC-9.
It's a little-known but equally intriguing subchapter in the yearlong fight between Blu-ray and HD DVD, two incompatible hardware technologies for high-definition DVDs, backed, respectively, by consumer-electronics manufacturers Sony and Toshiba.
Video codecs (a contraction of "coder-decoders") are important because they determine what quality of video can be squeezed into a given amount of digital storage space, or can be sent over a DSL or cable television line. The codec is an essential part of a DVD.
Microsoft surprised many two years ago when it submitted its Windows video technology, called VC-1, to technical standards bodies in hopes of seeing it appear on the new DVDs. Other technology giants hold patents in a rival advanced format called MPEG-4 AVC.
Last week, studio giant Sony Pictures quietly voted for "none of the above," and took a swipe at the new codec formats. The new advanced codecs aren't immediately necessary for discs released in Sony's high-capacity Blu-ray format, Sony Pictures executives said in an interview with CNET News.com, and the studio would instead use the 11-year-old MPEG-2 video codec used on today's DVDs.
"Advanced (formats) don't necessarily improve picture quality," said Don Eklund, Sony Pictures' senior vice president of advanced technology. "Our goal is to present the best picture quality for Blu-ray. Right now, and for the foreseeable future, that's with MPEG-2."
None of this alphabet soup of acronyms is likely to mean much to the average consumer. Once the discs come out, it will be a matter of matching a Blu-ray disc with a Blu-ray player, or an HD DVD disc with an HD DVD player. The discs should play as simply as they do today, no matter which underlying video format is being used.
But the studios' decisions could mean a great deal to companies that have invested heavily in creating or supporting the new video technologies. Microsoft has been betting that the adoption of its advanced video format by Hollywood studios, cable networks and satellite TV companies will help Windows-based devices capture a bigger share of the home entertainment market.

- Sony's Scared
- by bcsaxman November 29, 2005 3:44 PM PST
- All this talk about MPEG2 being cost effective or having better DRM misses, I think, the most obvious point this article brings up. Namely, that Warner Bros was going to make a BluRay hybrid based on cheaper DVD manufacturing techniques. With the better compression codecs, they would be able to fit a high def movie on one of these 9GB discs. Both things drive a stake in the heart of Sony's argument regarding BluRay's superiority to HD-DVD.<br /><br />We all know HD-DVD is the most cost effective of the two formats. However, BluRay champions constantly, and thus far effectively, use the greater capacity argument to offset that serious cost disadvantage. Now here comes one of your own backers with a plan that pretty much negates that assertion. I mean come on - if you can get even a 780p version of a movie on a 9GB BluRay hybrid disc, then the 15GB minium of HD-DVD is looking pretty damn good - especially for the money. 30 and 45GB discs are positively decadent! The whole house of cards Sony has built in justifying their push to make BluRay dominant just comes crashing down. <br /><br />When you factor in the other issues - such as the 3-5yrs either format will need to become as popular as DVD currently is, and the extreme likelihood that some other technology (maybe holodiscs, maybe high capacity flash memory) will supplant them both in that time - then the high investment costs of BluRay look even more ridiculous than sober assesments already make them out to be. If I'm Sony, I need to find some way - any way - to end the capacity discussion in my favor and get the cats herded once and for all. Enter MPEG2.<br /><br />With MPEG2 Sony has, finally, a legitimate case to make regarding capacity issues. Certainly Warner's 9GB disc plans are stopped in their tracks. And just as certainly, while HD-DVD will probably get a high def MPEG2 movie within 15GBs, it will be at a real disadvantage in terms of extras. That would be fine for a hybrid BluRay disc, but NOT for a technology that's trying to present itself as a full-fledged challenger to BluRay.<br /><br />Sony is adopting MPEG2 in order to bolster it's case that HD-DVD isn't 'big enough', and that the increased costs of 'going blue' are thus worth it. With MPEG4 or H.264 alone, that argument slowly reveals itself to be a red herring. With the same codecs on an even smaller hybrid BluRay disc, it's a big honking red light for any studio's CFO (not to mention the buying public). Sooner rather than later, all those companies - and the public - would wake up and give less support to Sony's format.<br /><br />Sony turning to MPEG2 is a last, desperate measure by them to keep their rhetoric in line with reality. If what this article says is true - that the studios will follow Sony's lead on this - then it may even succeed. But, all other considerations aside (which I think also favor HD-DVD in general) if this is what it takes to make BluRay a success, I'm becoming more and more convinced that HD-DVD is the better alternative.

- You really got down to brass tacks and hit the nail on the head (I love these overused cliches).<br /><br />I completely agree. This is the core issue of the matter.

- Thanks for the well written insight on the HD-DVD vs BluRay fight. BC Saxman I'm sure you must be a blogger or writer because your thoughts on the subject left me with a better understanding of the core issues then the News.com article. <br /><br />Good Job!

- If you look back at the history of the current DVD format, you'll see how the various studios have balked at the idea of providing a perfect digital copy. For those of us that were enjoying DVD back in 1998, you'll recall that many studios were very reluctant to release their prized movies. <br /> <br />I'm convinced that Sony is more than happy to use a 11 year old codec to distribute "HD" content just because it knows full well that the picture will remain less than perfect, and basically marginally better than current DVD's upconverted. <br /><br />Then when you figure that 80% of the US population hasn't even got around to fixing the default red-bloom color cast on their TV's, that almost half of them still prefer full-screen movies, and many only switched to DVD's because the video store/Wal*Mart did, means that the movie studios know the MAJORITY of consumers don't care about perfect quality anyway, hence MPEG2 becomming the easy standard. The less than perfect copy will keep the studios happy to relase movies in "HD".<br /><br />The videophiles amongst us will just look on this as a joke, and that in itself could kill the whole deal, since it's the early adopters who'll decide if HD DVD's take off at all.

- Taiwan just put their 'FVD' format into production. It is basically a tweaked DVD system using red laser and WMV HD - aka VC-1. The dual-layer discs hold just shy of 12GB.<br /><br />At that capacity they claim you can squeeze 135 minutes of 1080i HD content on the disc. Just video, no extras, etc.<br /><br />Warner wants to use VC-1 to put movies on an 8.7GB DVD. I've seen that done, for example the Terminator Windows HD disc, and the results aren't pretty. First of all, forget anything but the raw movie - much like Superbit. But even then, the longer the movie is, the worse it looks. The compression has to be turned up very high to get it to fit. For some of the longer movies out there, you couldn't get them on one disc.<br /><br />15GB is a bit better, but that's just a bit more than the FVD format. When you start talking about long movies (think Lord of the Rings), it is still tight.<br /><br />Blu-ray's 25GB on a single layer gives more room for HD extras, interactive content, etc. The kind of thing most consumers want. If all people wanted was the movie, all DVD's would be Superbit releases. But given the choice of a Superbit release or a standard release with extras, most people buy the latter.<br /><br />With home video sales dropping off, studios are looking for new hooks - so we'll see more games, extras, interactive content, etc. And that needs space.<br /><br />Blu-ray also offers a superior hybrid solution with the BD layers 'over' the DVD layers, for a single sided disc. No need for HD-DVD's compromise of HD-DVD15/DVD5, or the dual-sided discs no one likes.<br /><br />MPEG-2 is a better codec when there aren't space and bandwidth limits. I'd rather have a 1080i (or better, 1080p) video encoded with MPEG-2 with minimal compression over something squeezed into MPEG-4 or VC-1, especially if they have to compromise and drop it to 720p, raise the compression level, and drop all the extras.

- THE BIG PICTURE

- I disagree with your statement. Let's call it what it is. Microsoft wanted BLU-RAY to support it's codec, but in doing so, SONY would be indirectly "consenting" to HD-DVD standards. This battle is more than storage, it is a war for the next lucrative market, High Definition. There is a lot at stake, and for SONY to choose a trusty standard like MPEG2 over other compressed codecs, I perceive it as keeping something simple in the already complex world of BLU-RAY (new format, new manufacturing techniques, new media).<br /><br />Also I believe this has to do with the PC and Video Gaming industries. Microsoft's XBOX360 is the latest and greatest. It is not, however, fully "Next-Gen" since it uses an OLD TECHNOLOGY known as DVD, instead of the rumored HD-DVD drives when it was first announced. So Microsoft is NOT immune to it's own hypocrisy. When SONY's Playstation3 comes out, it will be a true "Next-Gen" console, and to deliver on that promise, SONY is possible taking a shortcut. MPEG2 is an easy and familiar technology that will ease the transition for the movie studios and duplication houses. And when it comes to PCs, when these drives are available for your PC, we will gladly welcome the additional storage space, especially those who use their multimedia features on PCs. Besides, Nero and Roxio support BLU-RAY burning. SO if you need to see your video in these other formats, get you a BLU-RAY PC Drive, with either Nero 7 or Roxio 8 installed, and have at it!<br /><br />Finally, I believe that BLU-RAY is the perfect marriage for HD for it has, to coin a phrase, "something old (MPEG2), something new (50GB Discs), something borrowed (DVD Backwards Compatibility), and something blue (LASER)"!
