HDMI 1.4a supports 3D formats

The latest version of HDMI released March 4, features enhancements for 3D applications, including the addition of mandatory 3D formats for broadcast content.

According to the HDMI Licensing LLC, HDMI version 1.4a also adds support for the top/bottom format that many broadcasters are expected to use.

As reported, Hollywood studios are pushing 3D to the home as a way to make more money on a growing number of 3D titles that were successful in theaters, ranging from "Avatar" to "Up." A standards effort launched last June to define a content format for stereo 3D movies was one of the first major actions in this direction.

At the Consumer Electronics Show in January, many companies claimed that stereoscopic 3D is ready for the home. But much work is still required to hammer out the standards and silicon for 3D TV products, many of which are expected to ship this holiday season.

In a statement, Steve Venuti, president of HDMI Licensing, said the latest enhancements were published to support the market need for broadcast 3D content. "When we launched 1.4 in June of 2009, we deferred the selection of mandatory 3D formats for broadcast content until the market direction was more clearly defined," Venuti said. "The market has spoken and the HDMI Consortium has listened and responded to accommodate those market needs."

The complete HDMI 1.4a, along with the 1.4a version of the Compliance Test Specification, is now available to adopters on the HDMI adopter extranet, according to the statement. An extraction of the 3D portion of HDMI 1.4a is now available for public download on the HDMI Website.

In addition to the top/bottom format, the new spec adds a second mandatory format for broadcast content, side-by-side/horizontal, according to HDMI Licensing. It also adds formats for 3D movies and game content, the organization said.
