HDMI Jumps on 3D TV Bandwagon
HDMI Licensing, the licensing entity behind High-Definition Multimedia Interface, is working to ensure that television programmers will be able to deliver upcoming 3D broadcasts to new 3D-capable HDTV sets.
The organization, which is a consortium of Hitachi, Panasonic Corporation, Philips, Sony, Thomson (RCA), Toshiba, and Silicon Image, announced that it is currently making the 3D portion of its latest HDMI specification, version 1.4, available for free public download on its Website so that television networks and and transmission vendors can get the necessary information to deliver compatible 3D pictures to new 3D sets.
According to Broadcasting & Cable, although these companies haven’t traditionally been licensees of HDMI technology, they need to know how the 3D aspects of HDMI function to ensure that early 3D broadcasts are up to snuff, which is why HDMI is making the information freely available.
The 3D compression techniques detailed in the new version include Frame Packing; Field Alternative; Line Alternative; Side-by-Side (Half); Side-by-Side (Full); Left + Depth; and Left + Depth + Graphics + Graphics-depth. The organization also announced in December that it will add the “Top/Bottom” frame-compatible technique, which ESPN plans to use for its 720p 3D HD pictures, to the updated 1.4 specification.
