Anandtech made a hint about bitstreming in the azuntech review. Something about not having to wait to long before its intergrated into graphics.


Could it be that the 5000 series support PAP?

Iam very excited to see the idle power consumption of the 56xx series. Propably it comes with GDDR5. I would bet that idle power consumption is around 6W.


Renexth, maybe it is worth to have a bandwidth column...

Finally we will be able to get a cheap solution for bitstreaming HD audio! (You need a copy of PowerDVD 9 Ultra.) But you have to wait until Q1 2010 if you want a midrange/low-end cards (HD 5670/5650/5550/5350). The following cards replacing the current HD 4770 are expected in October 23, 2009 and are relatively inexpensive:


- HD 5750: $149

- HD 5770: $199

My question is will the driver's DirectShow audio renderer support the WAVEFORMATEXTENSIBLE_IEC61937 format?

If the driver suppors it, media player developers can implement HD audio bitstreaming easily, right? If so, that's an interesting question.

Yeah, that's the plan.

Now MKV files with untouched TrueHD/DTS-HD MA audio tracks would be a viable option.

Yup. If they implement support into the driver. The Xonar did not not support the extentions on their DirectShow renderers (I was hoping they did). I don't know if the Auzen offering does or not (my wife would kill me if I tried to spend any more money just to see).


If the new ATI cards support the extention, you won't be able to sell a used Asus or Auzentech for the cost of shipping.


ffdshow tryouts supported the extentions for a while but they have been removed since no cards worked and it couldn't be tested. I also have my own "test" filter ready.
(Test meaning it doesn't actually bitstream but just checks if the renderer supports the extentions. I'll add the rest once a card supports them.)

BTW how do you check if the driver's DirectShow audio renderer supports the WAVEFORMATEXTENSIBLE_IEC61937 format?

I coded an audio "decoder" filter that, when connected to a TrueHD source from either the MPC demux or the ArcSoft demux, will set it's output pin for TrueHD bitstreaming according to that developer document. If it connects to the audio renderer, the renderer supports that extention. If the renderer does not connect, then the extention is not supported.


I've tested with the Xonar and, just for kicks, the 4760. Neither supported it (I didn't expect the 4670 to though).


Short of using a decoder that supports the extention, there is no real way to test.

I wonder how James is planning to make Slyplayer bitstream with 4000 cards.


In any case, it would also be interesting to see how the HDMI device shows up on the Windows panel, and if WASAPI exclusive works as well (or better) as the 4000 series. Unfortunately this card is too expensive for me, I'll have to wait at least until the 5750.

As long as PDVD9 (or 10 for the matter) is required to bitstream I'll stick to the TMT3/HDAV solution.

Isn't there still a problem with ATI cards passing proper 24p? Renethx, I think your guide indicates as much. I thought NVIDIA's cards could do 24p but were inferior to ATI in SD processing? Am I reading your charts incorrectly?


Thanks,

Alex
