Hardware ATI Makes False Claims on HDCP Support

ATI, most of its partners, retailers claiming shipping consumer cards are HDCP-ready. These claims are untrue
Last week, our very own Alan Dang posted a report about the current state of HDCP support in graphics cards. The article touched on several topics, such as what is HDCP, what cards currently shipping supported HDCP, and why were cards being advertised as being HDCP ready, were in actually not ready at all.
According to the HDCP specification, high-definition video content that is transported using a HDCP-DVI signal will be encrypted to prevent copying. If an attempt at copying is made, the video is scaled down to low resolution to deter copying. For a manufacturer that wishes to use HDCP technology on its products, a signup with the HDMI committee is required. Upon a signed agreement, the manufacturer must pay the committee an annual fee of $15,000 and a royalty fee of $0.15 per product sold. If HDCP protection is implemented, and a logo is used, then the fee is reduced to $0.04 per product. To actually implement HDCP protection, unique keys are required on a per product basis which is provided by the committee and requires implementation at the manufacturing level. According to NVIDIA, an extra chip is required that stores unique decoding keys.
Most of ATI's recent retail products are currently shipping with advertisements claiming that the products are HDCP-ready. On ATI's website, the term HDCP-ready was also used, for example on the X1900 series specifications page. Curiously, ATI's professional products such as FireGL list "HDCP-compliant". We spoke to ATI and asked it why the terminology difference and what the difference was in its view, between compliance and ready. Unfortunately, we did not receive a sound response to that question. In an interesting turn of events, today ATI has begin to silently remove references to HDCP-ready on its consumer products.
The image to the right is a screenshot that shows a Google cache of ATI's X1900 specifications page compared to what the specifications page is today. Google's cache clearly highlights the missing HDCP-ready claim that was present since launch. While FiringSquad's article presents a significant problem with ATI's claims of HDCP support, the problems go much deeper than expected.
A quick search on etailers such as NewEgg, CompUSA, Best Buy, and a host of other stores also list ATI's specifications, and most of ATI's recent products are listed as supporting HDCP. In fact, many of ATI's add-in board partners like Boxxtech, Connect3D, Diamond MM, HIS, PowerColor, VisionTek, and even Apple's online store, all list HDCP-ready. We've included screenshots of some of the websites boasting identical information to ATI's spec-sheets.
We spoke to a number of ATI's partners and asked if the boards were ready to output a HDCP-DVI signal and unfortunately the general answer was no. Some board manufacturers said that the boards that are currently shipping do not contain the HDCP decryption keys necessary to support HDCP at the board level. Regardless of the GPU, if the board does not have the necessary component and key, HDCP will not work. We further asked ATI's partners as to what possible reason board level support for HDCP was left out but the same reason was given almost unanimously: ATI did not consider HDCP to be ready because copy protection for Blu-ray and HD DVD was still up in the air, and therefore did not feel it was worth it to pay the licensing fees necessary to be fully HDCP-compliant.
This is where ATI's professional products differentiate from consumer level products. So if no money was spent on including HDCP support, why claim HDCP-ready? More AIB partners explained to us that upon the release of Vista, a driver update can be applied to enable HDCP output. Unfortunately, we already know that this is not the case as information can be found on hdmi.org. To enable HDCP, a board must include the necessary hardware and key at the time of manufacturing. NVIDIA stated that a BIOS upgrade, a driver upgrade, or retrofitting a board after the fact will not work.
AIB partners say ATI claims the uncertainty of Blu-ray and HD DVD is the reason why keys were not purchased. However, according to Microsoft's HD content protection documents, it is clearly defined that Windows Vista will ship with HDCP support and will also contain support for both high-defintion formats. ATI argues that HDCP may end up not being required for Blu-ray and HD DVD playback but according to the MPAA, this is not the case. Considering how hard the RIAA is pushing on MP3 copyright issues, the MPAA will be very adamant that high-definition movies be protected.
Visiting hdmi.org, several hundred supporters of the technology are listed on the adopters page, and ATI Technologies is one of them. With a significant amount of industry leaders backing HDMI/HDCP, and ATI's clear presence on the HDMI members board, the argument that HDCP might not be required is far fetched. Audio/Video products such as home receivers, flat panel TVs and other devices have been shipping with HDMI and full HDCP compliancy for well over a year now. In fact, Sony is already shipping PCs with full HDCP compliancy.
According to Godfrey Cheng, ATI's marketing director, it is up to the board partners to put in the necessary keys for HDMI-DVI decoding. Unfortunately, this still does not explain why ATI's own "Built-by-ATI" video cards also claim HDCP support when this is clearly not the truth. Users who visit ATI's latest website revision, especially for the X1900 series, are now greeted with a "fixed" specifications page that omits any reference to HDCP support. However, those who visited ATI's website before yesterday and purchased a any one of ATI's cards will be disappointed to know that they will not be able to play back HDCP-DVI signals, either from Blu-ray, HD DVD, or Windows Vista. A search on ATI's website on various consumer products now show "HDMI interoperable", which means there is either a physical HDMI connector available or a DVI to HDMI adapter supplied. This solution however, only outputs a standard DVI signal. ATI does not currently ship a consumer video card with an HDMI output.
The bottom line: ATI has publicized that many of its consumer products are HDCP ready, when in fact are not. Some products boast HDMI connectivity, when they do not even have a physical HDMI connector nor do the products ship with an adapter. Even if they do, having a HDMI connector does not mean the board is able to output a HDCP-DVI signal. Customers who have any one of ATI's currently shipping consumer (enthusiast, mainstream, gaming, entry level) products that were advertised to support HDCP were mislead. Many of ATI's add-in board partners also repeated the same specifications as those listed by ATI.
ATI was unreachable for comment at the time of publication. Instead, ATI's website has been changing gradually to remove any previous mention of "HDCP-ready" and specifications have been replaced with a more generic "HDMI interoperable" spec.
ATI has sold millions of products with a claimed feature that does not and will not work and most customers will not find this out until they attempt to play Blu-ray and HD DVD titles. As a company with an incredibly loyal following, this is a big issue that ATI needs to address to its customers immediately.
