Nvidia to present Pure Video tomorrow

So basically, the only GPU's that have "full" HDTV (MPEG2 + WMV9) support are the PCI Express 6600, and 6800 NU & LE

The rest of the GPU's have a reduced featureset in one way or the other. Most annoying thing imo is that the 6200 w Turbocache have a reduced featureset with HD decoding only up to 720 p. I wanted a fanless cheap 6200 in my HTPC but i want full 1080p support. Though i guess that you could make a 6600 fanless if you downclock it a bit and add a heatpipe solution.

And finally, no encoding support ?

I believe Gigabyte offer a selection of fanless heatpipe cooled 6600 cards (and 6600GTs + X700 Pros, too):

Well, this is rather interesting...and maybe perfect timing...

Yesterday, just for giggles, I connected up my 6800 GT based comp to my Sony KF60WE610 60" Grand Wega HDTV. After putzing around with it for about 30 minutes, I finally got the resolution somewhat right and text clear enough to read.

It was not as cut and dry as I would have thought, but then again my first attempt at using Nvidia's HDTV options. After all said and done, the picture looks reather impressive. Dvd's played rather well, in fact, better than my toshiba I'm replacing. Gaming, well, Doom 3 looked stunning and World of Warcraft, well - I don't think I can go back to my 17" lcd...

I have not tried any of the new Microsoft HD media samples but since everything is connected, I can putz around with that tonight.

The comp in question uses a PNY 6800 GT at stock clocks, Intel 865 motherboard, 3.0C P4, 1 GB ram, and 80 GB sata HD. Nothing to write home about but serves as a pretty good gaming and digital photo rig.
 
I'm just waiting for someone with a 6600 that can test the CPU usage with some 720p & 1080p movies.
 
ATI have sent out a document suggesting that the the MEdia Player 10 update sent out by NVIDIA only include their updates, not ATI's - the final will include both. They have indicated how to turn the WMV9 acceleration on throug the reg. Does Anand mention this at all?

NVIDIA sent us elements of a forthcoming update to Windows Media Player 10 that will further take advantage of PureVideo's hardware acceleration. At the same time, ATI sent us information on how to enable hardware acceleration of WMV9 on their cards before the forthcoming WMP10 update. The improvements are nothing short of impressive, full hardware decode acceleration cuts CPU utilization almost in half for both vendors.

Anyone here who knows if the HW accelerated WMV9 decoding will work on all Ati DX9 cards ? (at the same CPU utilization rates as seen in the Anand review)

I believe so, however I would imagine the performance could differ dependant on the number of pipes as they use the shaders to accelerate.

That's what i would expect too. Will be interesting to see if it's useful on the low end, f.e 9550 (a friend of mine has a 9550 in his HTPC and he's very interested in HDTV). And perhaps my 9600 Mobile.

All the test's I've done so far indicate that there is very little performance variation between a 4 pipe and 16 pipe board in video acceleration, however that is before the WMV9 acceleration which should put more onus on the graphics.

From what I've seen the AGP 6600 series will work too .. the 6800 Series won't though.

What did you test then, MPEG2 HDTV 720p & 1080p or ?

Btw, have any of the other sites done tests with a 1080p WMV9 ? Cause i noticed that Anand only used 720p examples.
 
Decoding, smoding. The big win we were sold on with the NV4x video processor was the ability to ENCODE. This opens up the ability to not only do a HD-PVR for 720p and 1080i, but to accelerate work in apps like Adobe Premiere.

Where's my accelerated MPEG-4/H.264/AVC encoding? :)
