CableLabs publishes specification for
formatting 3D content into frame compatible format
CableLabs has published a new specification called the
Content Encoding Profiles 3.0 Specification (OC-SP-CEP3.0-I01-100827)
as a guide for producers, programmers and aggregators of
stereoscopic 3D programming.
This new specification can be found on the CableLabs website,
www.cablelabs.com, under OpenCable Specifications.
This new specification details requirements for formatting
or "panelizing" the 3D content into a frame-compatible
format for use by cable television systems.
"This spec release marks a great step in the commercialization
of 3D TV because it is the first public specification that
fully describes the coding and signaling for these top-and-bottom
and side-by-side 3D video formats," said Tony Werner,
CTO of Comcast. Michael Kazmier, CTO of Avail-TVN, said:
"Ensuring that content from all programming sources
and cable systems is prepared in a uniform way will enable
a nationwide footprint for 3D programming and enable interoperability
with STBs and 3DTVs in the home." "A key part
of this specification includes the definitions for signaling
3D content over existing digital video infrastructure that
uses either MPEG-2 or MPEG-4 (AVC/H.264) coding," said
Jim Occhiuto, Vice President of Technology and Engineering,
Showtime Networks. "This signaling is critical for
the receiver/decoder to enable automatic format detection
and simplified user experiences when going between 2D and
3D programs," he added.
"This new CableLabs specification was developed with
support from cable operators, programmers and equipment
vendors and will be publicly available for any industry
to use," said CableLabs President and CEO Paul Liao.
The new CEP specification replaces the previous VOD-Content
Encoding Profile 2.0 specification that was widely used
within the industry. This new specification builds upon
the existing 2D coding framework and will be used as the
reference for both 2D and 3D video coding going forward.
Work continues at CableLabs on the development of standards
for the delivery of future 3D delivery systems.
