Supports 3D content in movies, games, broadcast
The HDMI organization has made the 3D portion of its 1.4 available spec for public download. HDMI spec v1.4 was completed in June 2009, but was only available to companies that had signed an HDMI Adopter Agreement. The announcement on Wednesday makes the new standards accessible to all other content producers and manufacturers.
The group also stated that an update to the specification, dubbed 1.4a, will be released in the near future, possibly to address a mandatory 3D broadcast format. The group had announced in December 2009 that HDMI v1.4 would add support for 3D content without the broadcast component.
HDMI v1.4 establishes protocols for several 3D display technologies including frame, line, or field alternative methods; side by side display modes, and 2D plus depth methods. It also includes data for the first time and supplies a 100Mbps Ethernet connection as well as two-way audio signals.
