| Post subject: | H.264 Decode Acceleration CES |
I was doing a little reading about CES this weekend and came across this on Anandtech http://www.anandtech.com/tradeshows/sho ... i=2665&p=2 It appears that NVIDA was giving a demo of H.264 HDTV using hardware acceleration on a Geforce 6600GT with a Pentium D 830. Before hardware acceleration it tanks the system at 100%. However, once hardware acceleration is turned on it drops the system to 50%. I realize that the demo is on Windows XP but this looks promising to lower future Knoppmyth HDTV CPU requirements. That should be reason to cheer... |

As long as this feature makes it into the binary drivers and isn't limited to Intel processors (one never knows...). |

Bastards... It also requires Windows DVD playback software. |

well not only that, but the broadcast standard for hdtv is MPEG2 not h.264, I suppose it might help for some newer iptv (if we can get it on linux) and downloaded videos. |

I was thinking that Mpeg2 could be transcoded more effectively to H.264. Then you could playback the video without many for the current problems like studdering, jitter, dropped frames, etc. on more moderate hardware. |

well I guess that would be possible, however if you don't already have a powerful enough computer to playback the MPEG2 hdtv it's going to take a day or so per show to transcode. |

There were several IPTV set-top box makers at the show. It was kind of funny actually. I wandered around and asked them all about content. "Uh, well, we have this box you see, so you can play your OWN content." They're all hoping to sign a deal with SBC or some other DSL network to provide their hardware. Nobody has content. |
