Now THAT is a useful feature.

That does sound like a useful feature lets hope they are right. For people that do alot of encoding that would be a big plus for nvidia over Ati if they don't offer the same thing.

Does R420 have something similar?

ATI theater chip (Theater 200 I think is the most recent) which is similar (but not as advanaced), but usually only comes on the AIW (it is available on ASUS cards, and maybe a few other VIVO cards).

The interesting thing is how much of the transistor count is taken up by this ('s on chip) or is it a separate chip like ATI does? The more stuff you add on-chip the higher the transistor count. And this may explain some of the number differences.

None the less very attrative, and hopefully worthy of some competition to the runaway favourite AIW.

The PCI-EX bus should really help with video transfer so it'll be very interesting to see what an R423-AIW and and NV45-personal cinema edition have to offer.

I hate the term <i> "High-bandwidth Digital Content Protection" </i>, sounds like digital-rights management, which makes WDMP/WMV9 suck right now.

Today I've read this at <A HREF="http://www.doom9.org" target="_new">Doom9.org</A> news.

<i>Then I got an email from an ATI PR rep about MPEG encoding and decoding support in GFX card. It appears that ATIs Radeon 9800 contains hardware DCT and iDCT blocks that can be used for MPEG-2/4 encoding and decoding. Furthermore, the chip does also support WMV9 decoding. However, at this point I'm still waiting to get a link to an official documentation on those features as the ATI website only mentions MPEG-2 decoding acceleration in the Radeon 9800 specs.</i>

I'm pretty sure they will find a trick to "optimize" benchmarks based on Video encoding/decoding to get the best scores against ATI...

And as usual, the image quality will be worst! But that is not important, because nVidia wants to be the BEST in every benchmarks!

Kind of sarcastic here...

Yeah, I wonder if these are exploitable in future Catalyst releases?

I'm surprised that they didn't do that already as I thought on board encoding and decoding was a requirement of the MediaEdition of Windows. Perhaps that's why it was built-in, but it hasn't been exploited because the demand didn't form.

Or it could be in there but broken perhaps and they just cant enable it just yet? Thats also a viable reason I would think.

Recent versions of DivX player support accelerated post-processing with R3xx series card. But there's no other application like this

I read that a few days ago.. not bad news but nothing I'm excited about..
wouldnt ever need it or need to have it.. my cpu does fine. And CPUs are astronomically great on price/performance since the original athlon release.
I could never get excited about the ati theatre features either... not a super selling point imo.
Those who need it, or could put it to use will be excited.

Nice to see NV putting some interest in the area... must be thinking of goign against the AIWs, waste of time IMO.
Just put out the fastest card with "the usual" in the software department, I dont even care if the filtering looks bad in a still screenshot at 8X zoom in fotochop.
Thats why I'm willing to drop $400US or more for the NV40.

Extra speed bump in encoding is always handy
