The Future of HDMI

by Tuan Nguyen

Is 2007 the year of the display format wars? A look at the licensing structures of these formats reveals more

HDMIUnfortunately, consumers will be faced a total of three display standards in 2007 -- and even more in 2008. Along with HDMI, computers will start to ship with DisplayPort and the Universal Display Interface (UDI) this year.  UDI is electrically compatible with DVI and HDMI, but does not carry the same licensing fees as either and has a stripped down feature set.  DisplayPort is not compatible with any existing signaling format.
One of the primary concerns for these new standards is cost and interoperability.  Expensive HDMI and HDCP certification is cited as one of the culprits delaying AMD 690G motherboards.
High fidelity signaling backers are split into two licensing camps: one supporting the DVI-derivatives (DVI-HDCP, HDMI, UDI) and the other supporting DisplayPort. AMD, Dell, Genesis Microchip, Hewlett-Packard, Molex, NVIDIA, Philips, Samsung and Tyco Electronics are supporters of DisplayPort; Hitachi, Panasonic, Philips, Sony, Silicon Image, Thomson and Toshiba compose the primary backers of HDMI. A significant portion of the DisplayPort supporters also have interests in HDMI.  Earlier last year, several manufacturers including Sapphire and PowerColor announced HDMI-enabled graphics cards based on ATI GPUs. MSI also announced HDMI cards based on NVIDIA GPUs.
When DailyTech asked why HDMI was taking a long time to appear in PC products, Leslie Chard, president of HDMI Licensing LLC, said "Right now most manufacturers are considering the cost of adding HDMI to their graphics products. Since HDMI is based mainly on DVI signals, the technology is already available in graphics processors. HDMI is everywhere -- consumer electronics, home entertainment and now companies are demanding the technology for smaller handhelds. You can't beat HDMI's cross platform compatibility."

Joe Lee, director of marketing for Silicon Image, added "Card manufacturers now only have to consider ways of grabbing the sound output through the PCI Express bus and adding the cost of the physical connector. If card manufacturers can finish writing the special [drivers] needed to grab the audio, everything would be set. Windows Vista should help drive HDMI forward."
According to initial reports, DisplayPort was heralded as a royalty-free technology. As it stands today, DisplayPort is royalty free but is composed with well over 200 patents. According to VESA, the committee that overlooks over the DisplayPort standard, the intellectual property (IP) holders are not held fixed and can and may charge a "reasonable" fee for the technologies used in DisplayPort.
Chard took a shot at DisplayPort, claiming "These IP holders are free to charge royalties under RAND [Reasonable and Non-Discriminatory] terms.  Until these IP holders make a public commitment, manufacturers have no idea what this rate will be.  Moreover, additional IP holders may come forward and charge additional royalties in the future; this is especially true if the DisplayPort standard ever evolves to incorporate advanced new technologies." 
HDMI's fees are already disclosed -- $0.04 per product and a small minimal fee for the HDCP keys, if used. HDMI Licensing LCC reduced the fees associated with using the technology late last year.
The largest hurdle DisplayPort faces, besides getting out the door, is interoperability with other devices.  DisplayPort is not compatible with HDMI, UDI or DVI.  The hurdle in jumping from one signaling protocol to the other is that the DVI-derivative protocols use HDCP, DisplayPort uses DPCP and HDCP.   VESA partners claim they will develop devices that allow HDMI to DisplayPort conversion, though doing so would mitigate DPCP.  Lee points out that this is essentially against the whole principle of a content protection protocol in the first place: if someone can freely negotiate between multiple or non-existent protocols that aren't under the same certification umbrella, then why have a certification process at all?
It has not been disclosed yet as to whether or not DisplayPort implementers may be required to pay royalties for the HDCP and Display Port Content Protection (DPCP) conversion either.
As of right now, the consumer electronics playing field is blanketed with HDMI-enabled products. The technology also recently entered its 1.3 revision, supporting features such as higher resolution and deep-color (wider color gamut) -- Sony's PlayStation 3 supports HDMI 1.3.  Philips, the inventor of DisplayPort's content protection scheme DPCP, recently announced a wireless version of HDMI.
AMD is expected to launch DisplayPort compatible GPUs later this year with NVIDIA opting for the standard as well. Early last year, Silicon Image stated that UDI will end up replacing both HDMI and DVI standards on the PC when it becomes available to reduce licensing fees, though it will still be compatible with the older standards.

CES 2007: Pioneer demos the future of plasma

Pioneer made some bold claims on Sunday about its brand spanking new plasma technology that should shoo of those pesky LCD and SED screens that have been sniffing around its turf. We were taken into a back room of the the Pioneer to witness the spectacle. Here, Pioneer had stood two 60" TV side by side, one using the current system, and the new one next to it.

The first me thing that struck me was that while the TVs sat idle, with nothing showing on the screen, you could still see the faint glow of luminance on the older tech one. The new plasma screen, however, actually offers such dark blacks that you can't tell whether it is showing a blank screen or has been switched off.

We kicked things off with a demo movie designed to show off all of its new features, such as the contrast ratio (which apparently is so good it can't be measured with standard equipment) and the richer colours. Then it was time for the side by side comparison and it became clear quite how much difference the new system makes. The colours are so much more vivd, skintones are a lot more distinctint and of course blacks look quite considerably darker.

To demonstrate how much better the new contrast works, the lights were turned up and down, and it was only when lights came up quite a long way that you could even begin to see any effect on the new screen.

One thing I did notice was that the new plasma was perhaps a little too black, and the colours a little too deep, which meant that the demo started to gain an unreal quality to it. Of course, you're unlikely to ever watch anything that even remotely resembles what they showed on the demo, so it might be best to take the results of this comparison with a pinch of salt. However, as it currently stands, it looks like Pioneer has delivered on its promises.

Westinghouse Quad HD on display


In the all hype that built up before CES this year we were really excited to check out the Quad HD display from Westinghouse. We went by the Westinghouse booth to check it out, the odd thing was the display was in the back of the booth and not marked very well. After receiving some help we found the display with some scientific data showing. Other than industrial uses we're not sure what we would use this 52" display with a resolution of 3840 x 2160. It would take one good scaler to scale the image that big.

Nakamichi Kimono LCD display

Nakamichi Kimono LCD display

CES 2007 - Nakamichi is well known for its line of home entertainment systems (especially those on the audio front), and this 42" LCD display comes with a hand-lacquered display which shimmers like the finish of a grand piano (read: fingerprint magnet). According to Nakamichi, the Kimono LCD display is pretty hardy as the 7-coat lacquer bezel is more than capable of standing against the test of time while retaining its beauty. You get the full 1080p experience as well as SRS TruSurround multi-channel audio which ought to keep you entertained for hours on end. The design looks rather weird to me, but it was still enough to pick up the Design and Engineering Showcase Award for a Video Display. I suppose I don't have a knack for appreciating abstract art. What do you think?

Meccano to unveil WiFi-enabled Spyke Robot Set

Meccano is all set to unveil a WiFi-controlled, Erector-branded robot kit at CES. The Spyke certainly improves on Meccano's earlier metallic attempts at robot sets: this little fella is capable of feeding a webcam video stream to a PC over the aforementioned wireless connection, as well as climbing stairs with its triangular tank-track; that's right parents, your staircase can no longer keep your kids safe. These basic specs combined with the teaser image on the right should be enough to perk up the ears of all the consumer robot enthusiasts out there -- who are now no doubt waiting to hear how competitively priced the Spyke will be in comparison to Lego's Mindstorm series of robot kits -- but unfortunately there's no other information (availability, pricing, etc.) about the Spyke as of yet. Don't fret though, because when CES kicks off in a couple of days, all will be revealed.

Norcent readies new plasmas / LCD HDTV for CES

by Darren Murph

While it seems we really only hear from Norcent when CES is approaching, the California-based outfit is kicking it up a notch this year as well, as it plans to showcase a duo of new plasmas and a flagship LCD HDTV as well. Both PDPs will feature integrated ATSC / NTSC tuners, HDMI, component / S-Video / composite, VGA, 160-degree viewing angle, SRS-enhanced stereo speakers, and a "3D digital comb filter" for color processing. Additionally, the 50-inch PT-5045HD plasma will sport a 1,366 x 768 resolution, 1,000 cd/m2, and a 10,000:1 contrast ratio, while the 42-inch PT-4246HD gets stuck with a 1,024 x 768 resolution and 8,000:1 contrast ratio, but picks up a Clear-QAM tuner and a 1,200 cd/m2 brightness rating. Over on the LCD side, the 37-inch VION LT-3790 one ups the LT-3725 we saw just recently by touting a larger panel, 1,366 x 768 resolution, 1,000:1 contrast ratio, 500 cd/m2 brightness, 176-degree viewing angle, built-in ATSC / NTSC (Clear-QAM) tuners, HDMI, component / S-Video / composite inputs, VGA, and the same SRS-enabled speakers as on the plasmas. For those interested in picking one up, the PT-4246HD is on the streets right now for a very reasonable $1,199.99, while the 50-inch flavor will land next month for $1,899.99, and the $1,199.99 VION LCD will hit stores sometime Q2 2007.
