False information in the articles: No UVD in R600

UVD is decoder, Xilleon is encoder to send data across Digital interface, like HDMI. I myself add UVD to Xilleon engine, to make one whole part of the HDTV 2D engine ATI has had on the market for quite some time.

http://ati.amd.com/products/dtv.html

Now, this is all part of HDCP schematic...each device, whether sending or recieving needs to have specific parts of HDCP compliancy. As Xilleon was already on the market, it was only a natural progression of this technology that would come to be known as "UVD", as Xilleon should have been set up properly in order to deal with the HDCP requirements. ATi has long been in the market for set-top boxes for cable broadcasts and HDTV, although not selling specific parts other than video decoders, RAMDACs and the like. Most peopel would be pleasantly surprised at the number of products that feature ATi parts...it wasn't videocards or chipsets that "sold the farm" on the AMD purchase.

Anyway, sorry for the confusion about Xilleon...that's entirely my fault.

But my card reads Theater not Xilleon. Or did I miss it on the card somewhere?

I´m just worried R600 simply dont do any, or just as X1950XTX. In that case you need a good CPU.

http://www.anandtech.com/video/showdoc.aspx?i=2886&p=4 (last chart)

A E6600 can barely do it with the help of the x1950XTX.

No..Theater/Xilleon are teh same technology, a UVD that provides copy-protection schemes/connectivity to digital devices.

The X240S & X240H are the first chips to integrate all the major components necessary for manufacturers to build digital integrated televisions at lower costs. The Xilleon 240S TV-on-Chip™ includes a Digital Front End capable of demodulating and decoding 8VSB for ATSC terrestrial broadcasts or 64/256 QAM for digital cable, a HD/SD capable MPEG video and audio decoder, a NTSC video decoder featuring a 3D comb filter, and a powerful MIPS® CPU (central processing unit). The X240S supports both digital and analog SD (Standard Definition) outputs.

the Xilleon is of course much more advanced.

This field proven chip includes an analog front end (AFE), Advanced Physical layer (PHY), Programmable DOCSIS 2.0 media access control (MAC), and an ARM 9 communications processor. Embedded interfaces include Ethernet 10/100 MAC/PHY, MII, USB 1.1 MAC/PHY, Silicon or Can Tuner interfaces as well as an I2C master for controlling additional AMD physical layer devices.

---

Both devices are "systems on a chip" featuring differnt functionality, altohugh the base "tech design" is the same, providing SECURE connectivity.

This is why UVD using no system resources(CPU) is such a big deal...at least to me...with it's included processor(which made me think this card would have "clock domains" such as nV's cards do), all processing tasks are done on the card; decode, encode, and post processing. All the cpu does is provide connectivity between the media device and the vidcard.

What this means is that like nV's G8x I/O chip, ATi's R600 should have either had this integrated within the gpu, or on a seperate device, as nV does. "Missing Mul", anyone?

The Theater chip you think of IS an input/out chip...and possibly what's alluded to in the "UVD", but "Theater 2xx" devices do not provide hardware decoding...nor do they provide HDTV connectivity...this chip is merely for the s-video/composite input/outputs.

HD 2900 XT decodes all HD formats even better then 8800. The way it is done is ATI problem not user problem. The decoding is working very good.

Also making a siticky of a thing like this doesn´t make much sense, but ok....
At least put in the first post those slides that show that the deconding made by 2900XT is very good, and not bad as some people want that it be....

Have you tested decoding yourself? With current drivers (8.37) there is absolutely no benefit of Radeon HD 2900 XT when decoding HD-DVD movies (VC-1 and H.264). Nothing like the figures you posted.

What about the HD2400vs8500 for h264/avc and vc1 hardware accel ?
which one batter ?

You mean to tell me that I am missing Xilleon as well as UVD??? :confused:

Back at CeBIT ATI announced that R600 WILL have UVD:

http://www.bit-tech.net/news/2007/03...deo_processor/



And I just saw this in wikipedia:

Among other details, the R600-series graphics cards features dual-link DVI output with HDCP, and provides an special designed DVI-to-HDMI dongle for HDMI output with dongle carrying sound data. However, as ATI stated that the Radeon HD 2900 XT (the R600 core) was developed earlier, the UVD features will not be presented, and graphics cards based on the R600 core will feature only basic AVIVO hardware decoding features for video streams.

http://en.wikipedia.org/wiki/Radeon_R600

I wonder where they got their info from.... And this site has reports of naming schemes/features, and they only list RV630 as having UVD:

http://www.answers.com/topic/radeon-r600

So now its clear R600 does NOT have UVD (or does not have UVD enabled). I think this is due to the fact that its already at 720million transistors, and seeing that UVD is ondie, it would just decrease yeild. That is why it will be present in lower models. Which would also make sense as to why original samples had UVD (hence CeBIT info).

So I think ATI did not inform AIBs that they had ditched UVD in the final retail revision of the R600.

PS. Add this to the front page sampsa :D

EDIT: There is one review that said it won't have it, and that is:

http://www.hardware.fr/articles/671-...d-2900-xt.html

Notez qu'AMD annonce l'UVD avec les Radeon HD2000. Il s'agit d'un moteur dédié à l'accélération vidéo et certifié capable de prendre en charge tous les médias Bluray et HD-DVD. Cependant l'UVD n'est pas intégré au Radeon HD 2900 XT, et se limite donc aux HD2600 et 2400, un peu comme le Pure Video 2 qui n'est pas présent sur 8800 mais sur 8600.

---

This makes no sense to me. This article is about 1 week old clearly stating that UVD (etc) would be added to the video card. This makes no sense to me because at the time of the interview video cards were already sent to stores for sale. How do we go from "using UVD" to "not using uvd" in a week's time frame?

In addition, the R600 is the first GPU that integrates the Universal Video Decoding (UVD) engine for hardware video decoding, plus a 3D engine for rendering. According to AMD, this configuration offers a significantly higher performance, since the workload of CPU during play-back of HD video is transferred to the GPU and specifically the UVD engine itself. In addition the shaders are off-loaded since video decoding is not dependent on the 3D engine.

Here something else, if you don't have UVD what's the point of the audio processor?

Its quite clear that UVD has nothing to do with HDCP/HDMI playback. It is something ATI introduced to remove the need for calculating the bitstream on the CPU, thats it.

http://media.bestofmicro.com/3/P/15685/15/15685.jpg

It helps with playback, but its not part of it. AVIVO works in a fashion similar to that of PureVideo2.

Offcourse. Look to your first post and read all David Bauman info:

You need ate least 8.38 to try something. Beside the drivers you have to have a HD player that suports Hardware decoding. Generaly those players are not free.
Also maybe you can have to install some software from Microsoft site. At least in Windows XP.

You are looking at the bark of the tree instead of the forest here. What I mean is that both UVD (etc) and the audio component compliment one another as a whole package. When UVD (etc) is removed it appears that you are not getting the whole package, IMO. If UVD (etc) was used you would have both a gaming rig and a HD/BR HTPC without worrying about having a high end processor and have a silent video card.

8.38 RC7 drivers were published yesterday to press and I tried decoding HD-DVD decoding with Radeon HD 2900 XT today. HD-DVD movie with H.264 codec was completely corrupted with Cyberlink PowerDVD and Avivo acceleration. With VC-1 HD-DVD movie CPU load dropped a little bit compared to 8.37 drivers (55 % -> 46%) but it's still alot worse than with 8800 Ultra and 8600 GTS (31 - 33 % CPU Load).

Sure. Now after rereading your comment it could be understood that way as well.

Delays, lacking specified features, bad drivers, not so great performance from such a novel chip.. why does this carry all the characteristics of the PS3?

NO, the Xilleon should have been the UVD integrated within the chip itself, or at least that was the plan.

Xilleon=UVD!

But UVD in r600 does not have to be Xilleon! Xilleon is current UVD tech already owned by AMD/ATI.

Do you have these RC7's, if you do any chance you could find a host for them?

I had a nice conversation with tech support. From what I am told Xilleon/UVD is integrated in the GPU. However, there is no driver that supports it yet. I asked him more then twice if that was accurate information. He appeared to be very sure about this. Only time will tell at this point.

Yes, we know Dave works for ATi.

Also, AMD's own press release states only the 2600 and 2300 have UVD, the 2900 lacks it.
