DisplayPort-To-HDMI Cables May Be Recalled Over Licensing

Hugh Pickens writes "PC Magazine reports that the licensing company overseeing the HDMI specification has confirmed that existing Mini DisplayPort-to-HDMI adapters which are designed by several cable makers and sold by several PC OEMs, are apparently illegal and could be recalled. According to Charlene Wan, director of marketing for HDMI LLC, any cable that does not include HDMI connectors on both ends violates the specification. 'The HDMI specification defines an HDMI cable as having ONLY HDMI connectors on the ends,' says Wan. 'Anything else is not a licensed use of the specification and therefore, not allowed.' That apparently includes Apple's mini-DisplayPort-to-HDMI adapters, which are sold by Belkin on Apple's Web site. However a representative for Belkin denies that the cable it sells on Apple's Web site is illegal. 'Essentially, the product you mention in your post is not out of compliance because it is just an adaptor and not a cable,' the representative wrote in an email. 'We do not sell a cable with a male Mini-DP and male HDMI port, which is what falls out of compliance with the spec. HDMI does recognize a product that has a Mini-DP connector and HDMI receptacle with an internal active circuitry as it falls into the definition of a source device.' There may also be a glimmer of hope, in that HDMI Org understands that there is a need for this type of cable: 'We do recognise that there may be a market need for a cable solution rather than a dongle solution. However, at this time, there is no way to produce these cable products in a licensed manner.'"

      It works both ways. Phillips refuses to allow the use of the CD logo on DRMed CDs because it violates the standard and isn't necessarily compatible with all CD players out there. In this case, I'm not sure what the solution is, but considering that it's purpose is to convert between the two types of ports, I'm not sure how much can be done about the problem.

      I don't understand what you mean with "both ways". Phillips is not crippling technology with their stance on the CD, in fact, they are doing the opposite by telling manufacturers that DRM is not a part of the CD-specification and might prevent consumers from playing those discs. Thus they are not allowed to be called CDs. The DRM is the crippling part, not the fact that the manufacturers that insist on having DRM on their discs can't call them CDs.

      There are five HDMI types altogether (ie. A through E). In the majority of cases most people would only see the type A connector which is 19 pins, however what can be confusing are the specs which are 1 to 1.2a, 1.3 to 1.3c and 1.4 and 1.4a. Basically if you have a 1.0 to 1.2a spec you are ok on 720p but you may have trouble with 1080p. With the 1.3a on spec you should be fine with 1080p and even 1080p 3D (The first Playstation 3 had a 1.3a spec HDMI connector and works fine with 1080p 3D TV's).

      The 1.4 spec has exactly the same basic spec as 1.3a to 1.3c but supports ethernet and 4k by 2k screen resolution (If these exist they won;t be cheap).

      A simple guide to choosing HDMI cables for just about all HD TV's (includes 3D) is, if you have a 1.3a and above spec you should be ok although I would limit your cable length to between 1 and 3 meters. Most new HDMI cables are normally labelled as "HDMI high speed" (1.3a to 1.3c spec) or "HDMI high speed with ethernet" (1.4 and 1.4a spec). Paying more than $10 to $25 (US or Australian) for a 2 meter HDMI cable is wasting money because you won't see any difference in performance.

      The HDMI royalty is $0.04 USD per device and has an annual fee of $10,000 for high-volume manufacturers. The Display port cable is royalty free however it appears that Display port cables are more expensive than the equivalent length HDMI cable by between 20% and 40% (do a price comparison if you don't believe me). Yes I am sure the HDMI consortium are ripping off the public :)

That is, retailers and distributors will have to remove the product from the shelves. There is no plan under consideration to go after consumers who have already purchased the cables for personal use.

    I think the answer lies in the DisplayPort connector -- why do some computers have DisplayPort and not HDMI?

    My sense is that the adapters either undermine connector licensing -- Wikipedia notes that DisplayPort is a royalty free standard -- or somehow threaten copyright controls built into HDMI, or both.

    BluRay has to use HDCP for HD video, which pretty much mandates HDMI, so TV makers have put HDMI on TVs, and from there it became something of a home AV standard. Computer makers didn't need HDCP, so they went with the royalty-free solution, which in turn has been easy to connect to HDMI displays with an adapter. I note on Newegg that there are a number of monitors available with DisplayPort, so it's possible to go all-DP on a computer setup.

    My best guess is that with so many people wanting to plug a laptop (no royalty) into a TV and at least some display makers willing to add DP, the future for HDMI as a standard is perhaps threatened and revenue is certainly decreased by 50% in some future world when only half the devices use your connector.

    And if you think even not that further out, there may be a future where nobody buys a "TV" anymore -- you buy a display with either in-built intelligence to view programming from network(s) or you attach some computing device. If the latter has DisplayPort and this is what most people do, then the TV doesn't need HDMI and the standard withers, much to the chagrin of the people cashing royalty checks, and to the movie studios who want the DRM.

    The Cables used to extend USB Cables, which were bundled with hundreds of Consumer Devices were illegal too, according to USB 1.1
    That didn't stop manufacturers like Logitech and Apple including them with Peripherals. (Apple's extension cables were slotted to prevent anything but Apple Keyboards to connect to them)

    The USB-IF amended this clause in later versions once they realized that they couldn't do anything about the thousands of products already on the market that violated the license.
    Hopefully, either HDMI LLC wise up too, or Display manufacturers start including Royalty-free Display Ports on their devices. Display Port supports the xvYYC colourspace and even CEC now, which almost makes HDMI redundant.
