WMVHD High Definition Video
Microsoft has been making its own path into the high-definition
DVD market for quite some time now. We were able to
see a demo of WMV HD on a very nice plasma display (at
720p) which was simulcast on a computer LCD monitor
at 1080p (yes, that's 1080
p
- ah, the wonders of PC video cards). The format is
impressive and is a definite improvement over standard
480p DVD output. Apparently, Microsoft's codec is able
to produce incredibly clean high-resolution video with
a bandwith of only ~8 Mbit/s. The MS rep seemed to feel
that Microsoft is a contender for the HD DVD "war"
primarily because they have a solution that already
works... trouble is, I'm not sure a singularly PC-based
solution is the answer. At least not until grandma and
grandpa are buying home theater PCs at Best Buy. Some
quick points of interest:
- 720p and 1080p support
- Roughly 6x the resolution of DVD video
- Windows Media Audio Pro (WMA Pro) allows for delivery of 5.1 and 7.1 surround content
- Authoring solutions available from Playground, Sonic, Canned Interactive, InterActual, Mastery, and Shanghai Broadcasting Laboratories
- Digital Rights Management (DRM) available from SyncCast and Macrovision
- Testing and authoring companies are in place to produce content and test final DVDs
Addendum: According to some feedback we've been receiving (thanks, Wayne) WMV is trying to get DVD makers to license WMV technology so that DVD players are sold with WMV decoders. This is similar to how DVD players have MP3 decoders, and are now starting to appear with Divx decoders. What this would do is allow HD using the existing DVD structure - the problem is, you may not be able to fit one whole movie at 1080p on one DVD.
Software is always the breaking point, so we'll have to wait and see what happens.
