It was then indoctrinated as VC1. VC9 is a public codec, VC1 its formal MPEG release, and WM9 a Microsoft PC-specific version for which they retain the right to make changes to the WM9 codec. MPEG-2 video coded is old, ineffecient, etc. and I've know a couple of high-end projector manufacturers that were more than delighted to use WM9 HD clips instead of MPEG-2 based HD clips for demonstrations at exhibitions and conferences. Using MPEG-2, a standard 19.1-Mpbs HD broadcast feed would require about 9GB of storage space and half that for VC1. And unless you have actually seen some of the Microsoft HD WM9 clips I think you would be standing on a thin foundation of bashing the codec. A video codec is independent of the copy-protection and playback system being used.

XBL2009 ------ join:2001-01-03 Chicago, IL ·AT&T Midwest	reply to audiog said by audiog : Yes I agree. WMP 9/10(MPEG 3) are up for DVDHD certification as the file format for the next gen DVD players. The other format is Blueray( MPEG 4) backed by Sony and the other computer hardware manufacturers. Half of the DVD governing body wants WMP 9(MPEG 3) format and the other wants MPEG 4 video and audio. This has caused the MPEG 4 backers to break from the DVD governing body and to form the Blueray group a independent governing group. Now the IEEE guys are trying to mend the breakup and now the Blueray group is considering supporting WMP 9 and MPEG 4 as file formats. So WMP 9( MPEG 3) is a natural test bed for IP TV but they should be looking at MPEG 4 also. MPEG 4 is 30% more coding power the MPEG 3. This link will explain the difference between MPEG 4 and 3: »www.telos-systems.com/?/techtalk···ault.htm HD-DVD and BluRAY support WMV9, the differeces between the two formats is surprisly little except the size of the storage.

HD-DVD and Blu-Ray can support anything because the arrangements of the bits are irrelevant to the disc's physical format. HD-DVD uses 35GB and requires very little retooling work to be done in manufacturing to get the drives out. Blu-Ray uses 25GB on a single layer disc and 50GB on a dual layer disc and requires some changes to existing factories so they can manufacture the drives. It supposed to be initially more expensive to manufacture than HD-DVD. -- "The bad news is that we are told that Michael Powell, one of Washington's better bureaucrats, is calling it quits today after four years at the helm of the Federal Communications Commission." - WSJ 2005/01/21
