    News item over at NYTimes mentions the coming 'format war' getting more complicated with divx6's arrival or is this just PR hot air?

    Are they saying that in any event, even if DivX6 had commercial entertainment uses beyond PCs, you'd still require specialist hardware to play it anyhow? A normal DVD player wouldn't do the trick but normal DVDs would be able to be used instead of blu-ray technology? Is that what this is all about as I couldn't quite see what was so great about it myself...

    You can try out Divx HD now, there's trailers available on their HD site.

    As it says in the article, Divx HD material results in smaller files (more compressed), so that you don't need the extra storage of HD-DVD/Bluray - hence you can fit a Divx HD movie within the capacity of a DVD. You would need a Divx capable DVD player though (or a PC) to play it back.

    It also doesn't look quite as good as the other formats, since the compression is a little more lossy.

    Is Divx HD the same as Divx 6 (as mentioned in the article) ?

    There's nothing that the so called DivX can do that WM9 - HD (VC1) can't and has been able to do for a long time - encode and decode hi-def material using MPEG4 based high efficiency codec (including piracy activities). VC1 is part of the HD-DVD and BD specifications, DivX6, 7 or 100 will never be adopted by any studio and big name electronics manufacturer. It will only remain a piracy tool of lower quality than VC1.

    Though it is also important to remember that VC-1 is a Microsoft standard (and some broadcasters have expressed concerns about the licensing model proposed to use it)

    MPEG4 H264 AVC seems to be the best bet for future HDTV broadcasts via conventional broadcast delivery systems (over-the-air, satellite and conventional cable) - and AIUI MPEG2 and MPEG4, as well as VC-1, support are part of both the HD-DVD and BluRay proposed standards for pre-recorded HD stuff.

    VC-1 is gaining ground in the more IT-centric video over IP sectors (especially IP supported VOD)

    MPEG4 H264 AVC is also the standard chosen by the DVB consortium to accompany MPEG2 as the DVB HD encoding standard.

    AIUI MPEG4 H264 AVC codec hardware is going to be available before VC-1 hardware (as Microsoft have been slower providing reference streams etc.?)

    MPEG4 seems to have the edge over VC-1 at the moment.

    Divx is a much more PC-based standard - fine for downloads at OK quality - but not a proposed broadcast format for the mainstream AFAIK.

    Yes, I have pretty much the same expectations about the future of the mentioned codecs.

    Not actually true. WM9 is a Microsoft standard but VC-1 is the SMPTE name for the advanced profile which Microsoft are putting through SMPTE as an open broadcast standard.

    The licensing for VC-1 cannot be finanlised until the standard has been approved but it is likely to be similar to the H.264 license since it has many of the same patent pools. The licensing for WM9 is a different beast.
