Incomplete 3DTV products in CES spotlight
HDMI upgrade one of latest pieces in stereo 3D puzzle
by Rick Merritt

SAN JOSE, Calif. — In a wide range of demos, companies will claim at the Consumer Electronics Show in January that stereoscopic 3D is ready for the home. In fact engineers face plenty of work hammering out the standards and silicon for 3DTV products, most of which will ship for the holiday 2010 season.

Hollywood studios are driving 3D to the home as a way to make more money on a growing number of successful 3-D titles at the theater ranging from "Avatar" to "Up." A standards effort launched in June to define a content format for stereo 3D movies was one of the first major actions in this direction.

Much more is still ahead. Observers expect many demos at CES of 3DTV sets using content from stereo-3D enabled Blu-ray players, thanks to a newly minted Blu-ray spec for stereo 3D. However most of the players and many of the TVs will not be available until later in the year when new chips for the spec are available.

Beyond the Blu-ray effort, multiple standards and chips based on them are still in progress. The latest is an upgrade of the HDMI interface that will pave a way for future stereo 3D broadcasts to be available on new and existing HDMI links.

The HDMI Licensing group is adding support to its version 1.4 spec for the top/bottom format that many broadcasters are expected to use. The format squeezes information about left and right eye images on to a single frame to save bandwidth, albeit at a loss of some resolution.

An HDMI implementation of the top/bottom format will be defined in meeting of the group in January. "I have been told by the technical team that this is not a hard exercise," said Steve Venuti, president of HDMI Licensing LLC.

So, this time around they realized they missed top/bottom formats, then they will come to realize they also missed row interleaved format, then they will realize they missed TI's checkerboard (quincunx) format, and then again they will realize they missed 120 Hz frame sequential format (since it's out of maximum possible bandwidth), etc...

It seems like HDMI Licensing LLC are just happy to collect multiple licensing fees for each subsequent revision of the standard. Why can't they apply some forward thinking and define all these formats right from the start? Instead, they are just fighting with the fact that very few devices adopt the features they specify, by forcing the licensees to never mention the version of the specification and list individual features instead.
You shall not use HDMI version numbers in the labeling, packaging, or promotion to consumers and consumer-related customers (such as retailers and retail distributors) for any non-cable product after January 1, 2012, except for components - see 2.3 below.

This includes releases of the HDMI specification (for example, HDMI 1.4, 1.3, etc.), interim version numbers (for example, HDMI 1.3a, etc.) and CTS (Compliance Test Specification) version numbers (for example, 1.2, 1.3c, etc.).

(On a positive side, they forbid assigning brand-specific names to HDMI features - which many brands did with the HDMI CEC command set, creating (incorrectly) an impression of a brand-only feature which will only work with similarily branded devices).

i Swear these people behind HDMI are reatarded.

Do they even remmember the incredibly underused optical cables for audio? why not just build on that. Take the optical cable, and put your stupid HDMI interface in it, bandiwdth problems solved for eternity.

HDMI has brought nothing but trouble, it makes something that should be so simple, into something overly complex, all this just to "fight" piracy, which we all know has done nothing like that.

SUNNYVALE, Calif., December 23, 2009 – HDMI Licensing, LLC, the agent responsible for licensing the High-Definition Multimedia Interface® (HDMI®) specification, today announced, on behalf of the HDMI Founders, the following regarding 3D formats and the HDMI Specification Version 1.4:

1.In order to respond to recent input from the industry, the HDMI Consortium will meet in late January 2010 to add an additional 3D format (tentatively named “Top/Bottom”) to the HDMI specification, supporting the use of this format over HDMI.
a.The exact date for this announcement is undetermined. The Consortium has committed to resolving this issue in January 2010 and publishing a document soon thereafter.
