3D-TV Broadcast Standard Development Making Good Progress
The ATSC’s exciting development of three-dimensional (3D) broadcasting – a new TV standard that will provide methods for transmission of 3D-TV content to both fixed and mobile devices – is making good progress. Chaired by Dr. Youngkwon Lim, the S12 Specialist Group on 3D-TV is finalizing requirements for 3D-TV services. Requirements under discussion cover 3D-TV services for fixed reception and hybrid delivery using non-real-time, broadband and mobile.
Urging members to participate in the important work of S-12, ATSC President Mark Richer calls standardizing 3D-TV over-the-air transmission “a key part of our ongoing effort to expand the capabilities of the ATSC suite of digital TV standards.”
S-12 has defined hybrid-delivery 3D as 3D-TV broadcasting service composed of two coded video images, where one image is transmitted via ATSC A/53 terrestrial broadcasting, and the second image is transmitted via another means. Service compatible 3D is defined as 3D-TV broadcasting service composed of two or more compressed video images, where at least one of them is the legacy 2D TV image having the same resolution as the production resolution.
Dr. Lim, who represents Korea’s Electronics and Telecommunication Research Institute (ETRI), reports that S12 has received technical proposals on service-compatible hybrid coded 3D-TV services, delivering an additional view compressed with an advanced codec in the same terrestrial channel, while using the legacy 2D service as a main view. S12 will start to draft technical specifications soon.
“The addition of 3D-TV capability to the DTV broadcast standard will foster new broadcast services while preserving the integrity of legacy TV receivers by adopting a system that allows for simultaneous delivery of 2D HDTV, Mobile DTV and 3D programs within the same channel while ensuring backwards compatibility,” Richer says.
Get involved! S-12 meets via conference calls roughly every other week. The next face-to-face meeting will be held May 23-24 in Korea. The meeting, on Jeju Island, kicks off May 22 with viewing of field trials of fixed and mobile hybrid service, hosted by the Jeju Technology Park.
