Just a few short weeks ago, Atlona threw in its support for DisplayPort by promising to deliver cabling for the freely licensable format. Lookee here, the AT16010-X cable lineup will be available at the end of the month in lengths from 1- to 10-meters, with either male or female terminations. Prices start at $39, which seems reasonable. The bigger question, of course, is whether DisplayPort will thrive in the HT marketplace; if it only exists alongside HDMI, its license- and royalty-free nature free-license nature is moot. As much grief as we give the HDMI connector, we don't relish the thought of swapping out equipment for a new cabling standard, either.

Move over HDMI, DVI and DisplayPort, here comes DIVA (Digital Interface for Audio and Video). Cooked up by the above group of Chinese manufacturers, they say this standard can improve on HDMI by enabling bi-directional data connections above and beyond HDMI-CEC protocols, creating easy DLNA connections between devices with a single cable. Forward channel video speeds of 13.6 Gbps provide plenty of room for 1080p and higher resolutions with Deep Color, plus the two-way connection at up to 2.25Gbps that can simultaneously handle multichannel audio, control or other data. With a working demo shown over a single 8 wire CAT6 cable, it's got specs that interest us, and with a growing AV market in China maybe these companies have enough pull to get wider support. Still, until someone produces a platinum cable measuring 3-feet long that costs $200 we won't be sure of its success.

Make no mistake, Atlona's a bona fide supporter of HDMI, but it's making absolutely sure you know that it will also be throwing its support behind DisplayPort. Of course, all it's saying at the moment is that it will soon be providing DisplayPort cabling "for as long as one of its customers has a need for one," but it looks like we'll have to be patient before finding out what other sort of DisplayPort contraptions the firm has up its sleeve.

Ugh, is DRM coming to shackle USB too? You betcha. The USB Implementer's Forum is planning to rollout a variant of tethered USB in 2008 to carry compressed high-def video between TVs and mobile devices. It appears unrelated to USB 3.0 and targets both laptops and personal media players -- however you might choose to define that. A spokesman for the organization said that developers "could layer HDMI's HDCP encryption on top." So it's not definite. But with the studios fighting hard to "protect" their content, well, it's a given that some form of DRM will be there. The new USB linkage is meant to complement HDMI which primarily carries uncompressed video between living room A/V equipment... and an increasing number of media-centric laptops. Thing is, DisplayPort, expected to make a big showing at CES in January, already comes with a slathering of HDCP and is the purported VESA standard for moving HDTV from your laptop to a digital television. To confuse matters more, Kleer Corp is also working on a mid-2008 wireless and wired technology for carrying SD video based on its existing wireless audio technology. Proof that the best part about having standards is that there are so many to choose from.

Get ready for hot, hot convergence kids 'cause the DisplayPort 1.1 specification was just approved. The new VESA-approved digital interface standard is meant to replace DVI and VGA ports while co-existing with HDMI for HDTV connectivity. As you can see in the picture above, it's about the size of a USB connector yet offers 2x the performance of DVI in a much smaller package. They also bake in a nasty dollop of HDCP 1.3 content protection to keep the Blu-ray and HD DVD kiddies happy. The wee size allows the interface to be included in smaller handheld electronics while enabling direct-drive LCD panels thereby eliminating the need for non-panel LVDS electronics in the monitor designs. Of course it also supports pass-through of DVI and HDMI signals via simple adapters similar to DVI-to-HDMI variety on the market today. So which of our esteemed manufactures will bite first? We're not sure, but VESA isn't shy about using Dell's high-end XPS systems in their marketing collateral. Of course, the question they don't answer is, why not just move everything to HDMI? For that, you just have to look at who backs royalty-free DisplayPort (the PC industry) and who backs HDMI (the consumer electronics industry). Yeah, we know.

Analogix Semiconductor just announced its first receiver chip for the DisplayPort interconnect. Yeah, DisplayPort, the latest video interconnect standard which looks to replace HDMI, DVI, and even analog VGA connectors currently found in monitors, TVs, laptops and other portable consumer electronics. What's more, it's fully supported and even, preferred by the Video Electronics Standard Association (VESA) as a low power, low pin count, license-free video interconnect standard. The ANX9811 chip is now available to manufactures for sampling and, when paired with the company's existing ANX9801 transmitter, supports a full 10.8 Gbits/second data rate and WQXGA (2560×1600) resolution over a 15-meter cable. Fine. But the real news here is that the chips will support the DisplayPort 1.1 spec which was proposed in November and should be finalized by VESA in early 2007. The modified spec brings support for DisplayPorts own copy protection technology and now, finally, HDCP. It's not that we're big fans of HDCP or anything, but if we have to be saddled with wire-line encryption, let's choose one and be done with it, eh? Expect to hear more about DisplayPort at CES where Dell, HP, Lenovo, and Samsung will be laying out the interconnect's roadmap in an fractured industry love-fest. Still, like any good standard, you'll have choices: Intel's also pushing their UDI (Unified Display Interface) interconnect to replace both DVI and HDMI in PCs. If we're lucky, Adam Smith will grab whole lot by the throat to shake out a unified standard before the decade is up.

Ok fess up, who requested another digital interface for video and audio content? Since UDI, HDMI & DVI weren't complicated enough, VESA has come out with their own digital connector to replace VGA, DisplayPort. They originally announced it a year ago, but it is now ready to go, the only question is does anyone care?

This article from Digitimes breaks down the challenges DisplayPort faces and what (few) benefits it offers. Unlike DVI/HDMI/UDI, it isn't backwards compatible with anything. If you replace your PC, DVD player TV or monitor with a DisplayPort device you'll have to replace anything connected to it. It also has it's own content protection scheme, much like HDCP, but once again not compatible.

We don't really see this standard taking off with no backwards compatibility (however this release from Dell/HP/Lenovo indicates it is "possible" to have legacy compatibility with DVI 1.0) and both high definition DVD formats using a different copy protection format. With its only apparent advantage being a lack of licensing fees, is there a space for DisplayPort?
