Re: .... no thanks
said by XBL2009  :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.

When Microsoft handed the VC9 video codec to the MPEG forum they did so giving them a gift. 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. |

The thing that pisses me off the most is when the article mentioned that SBC can prevent viewers from fast fowarding through commericals after recording to their DVRs. |

Re: greed and stupidity
Xvid? Oh please, this is not a serious codec. MPEG-4 is at least developed by serious groups (ITU's Video Coding Experts Group and ISO/IEC).

They are dumb to give up fiber.
They are even dumper doing it with microsoft.
Xvid codec is virtually royalty free and open source, and fully mpeg4 compliant.
Microsofts codecs are very expensive to use and lousy.
But who cares, you will pay for it. |

SBC executives in San Antonio have been testing the carrier's IPTV service for 45 days or so. The service is being fed from Austin, where five local San Antonio channels are being fed from Echostar, compressed with Windows Media 9, and sent via optical link to SBC's San Antonio offices. More fleshed-out residential trials for IPTV will begin in April. Yeah, so they do see the benefit of fiber -- just not for their peasant fiefdom? 'Frick'n genuises have no frickin clue how their meager f2 copper pairs behave when wet -- even at low 5mbs speeds. Their ratty f2 copper pairs are gonna choke at 20mbs. What fools. "If you can't afford to do it right (FTTP) -- you sure as hell can't afford to do it over". This'll be one of those MBA case studies in corporate stupidity. Incredibly SBC can afford $16 BILLION for some corporate incest with a dying company like AT&T -- but they're upgrading their cash cow on-the-cheap in hopes that their customers are too stupid to know the difference. I can tolerate idiots, but not fools.

Re: .... no thanks
pnosker is right, MPEG-3 doesn't exists.
Also, the Microsoft video codec is known as WM9 or VC-9 not WMP9 which refers to Windows Media Player 9.
Both MPEG-4 (H.264) and WM9 have been shown to achieve comparable quality to MPEG-2 at half the bit rate.

I thought that WM9 is the best codec available.
It may be because it is from Micro$oft (OMG!! I uzed doller sine l0l!) and everything they make sucks by default. |

Er.... this link is Audio (Layers referring to audio layers). AAC is a competiting standard against MP3. mpEG4 and mpEG3 are not the same.
From Wikipedia:
MPEG-3: Originally designed for HDTV, but abandoned when it was discovered that MPEG-2 was sufficient for HDTV.
MPEG-4: Expands MPEG-1 to support video/audio "objects", 3D content, low bitrate encoding and support for Digital Rights Management. A new (newer than MPEG-2 Video) higher efficiency video codec is included (an alternative to MPEG-2 Video), see H.264.
»en.wikipedia.org/wiki/Mpeg explains it a little bit. |

Look at my post above. MPEG 3( WMP 9/10) is not as good as the new MPEG 4 which is 30% more coding power. MPEG 4 makes MPEG 3 sound and look like MPEG 2. MPEG 4 is the first to pass some of the loss-less test. Very little phase shift. |

Unless its $5/month for 200+ channels, I don't think so.
Also, being that its running Media Playe, I wonder if they'll have cookies on it to track which channels you are watching

Also consider what they'll be competing against. Anyone who has used Time Warner's Scientific Atlanta digital cable unit and service knows that generally speaking with some exceptions, the image quality out there in the cable sector is not very high.....I think you could generally field crap and be competitive if it's marketed well. |
