Is this hilarious or what?
You have to be wary when manufacturers claim they will continue to
support something that is going to become irrelevant. HDMI's future
might not be so assured. Time to move on to other IP.
Then again, I also laughed out loud when I first read about UDI, not
long ago, and how long did it last?
What a circus.

UDI dies as Intel, Samsung back DisplayPort

LAS VEGAS - Intel and Samsung officially put their weight behind the
Displayport 1.1 specification at a press conference at the Consumer
Electronics Show here Tuesday (Jan. 9). With their support the competing
Universal Display Port (UDI) effort is essentially dead.
DisplayPort backers see the interconnect as the digital successor to
analog VGA, the Digital Visual Interface used on TVs and PCs and the Low
Voltage Differential Signaling links used inside notebooks and monitors.
UDI, a variant of the High Definition Multimedia Interface seeing rapid
uptake in HDTV sets.
Intel and Samsung, along with chip designer Silicon Image which owns
much of the intellectual property to HDMI had supported UDI. UDI was
publicly launched in late 2005. But UDI activity slumped after the
DisplayPort effort emerged with backing from major PC makers including
Dell, Hewlett-Packard and Lenovo as a standard of the Video Electronics
Standards Association (VESA).
"Samsung has been the only panel makers involved continuously in both
efforts," Brian Berkeley, vice president for advanced technology, in the
LCD unit of Samsung Electronics said at the CES press event.
"At this point we have received many inquiries about DisplayPort support
from major computer companies and no inquiries about support for UDI,"
Berkeley added.
Simon Ellis, an Intel technology manager whose business card still reads
"UDI Champion," said his company also now backs DisplayPort 1.1 as the
way forward.
"We realized two PC technologies could not be successful," Ellis said.
"The connector is the stickiest component in the PC. There is huge
resistance to any new connectors because once you put them in and have
third party products linking to them, it is very hard to take them
away," he added.
Intel has been quietly working in the background for about a year to
port its High-Bandwidth Digital Content Protection (HDCP) software from
HDMI to DisplayPort which uses a very different architecture, said Don
Whiteside, director of technology standards and policy at Intel. HDCP
version 1.3 is now available for both HDMI and DisplayPort.
Three chip makers are working to integrate HDCP 1.3 into their sampling
chip sets. They included Genesis Microchip. (Alviso, Calif.), Analogix
and startup Parade Technologies Inc. (Sunnyvale, Calif.) which is
focused solely on DisplayPort silicon.
Bruce Montag, a technology strategist for Dell, made the case for
DisplayPort. Because it can replace VGA, and DVI external and LVDS
internal links it will support large volumes and thus low costs PC
makers like. It has an extensible micro-packet-based architecture,
unlike the raster-scan architecture of HDMI and thus can support novel
features for video and voice calling. And it supports a road map to quad
HD displays and beyond.
Bob Myers, a distinguished technologist in HP's display unit, said HDMI
will continue to be an interface well suited to HDTV sets where it was
used in as many as 60 million systems last year. DisplayPort, but
contrast will be used on PCs, PC monitors, projectors and notebooks, he
said.
"We don't see competition between HDMI and DisplayPort. They will both
be used in different markets," Myers said.
However, in today's convergence markets companies such as Dell and HP
sell big-screen TVs to link to Media Center PCs as well as set-top
boxes. That means the two will ultimately come into some market
conflict, a reality for which HDMI backers are already gearing up.
Les Chard, head of HDMI Licensing LLC, said HDMI has been and will
continue to be used in a growing group of PCs and has unique advantages
over DisplayPort.
"We are every bit as fast as they are, and we are not limited on data
rates in the future," said Chard in an interview at a separate CES event
on Sunday (Jan. 7).
Some OEMs have chafed at the four cent per port royalties and $10,000
annual fee charged for HDMI licenses. Chard said although VESA is making
DisplayPort available freely, companies behind the spec are allowed to
charge reasonable and non-discriminatory royalties, which are yet to be
determined.
Some have also charged HDMI lacks ac coupling which prevents the silicon
from going into fine process technologies needed for future integrated
chips. AC coupling is "what's next on our road map," said Chard.
