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."

It's a little-known but equally intriguing subchapter in the year-long 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.”
