“This spec release marks a great step in the commercialization of 3-D TV because it is the first public specification that fully describes the coding and signaling for these top-and-bottom and side-by-side 3-D video formats,” said Tony Werner, CTO of Comcast.
Ensuring that content from all programming sources and cable systems is prepared in a uniform way will ensure interoperability with set-top boxes and 3-D TVs in the home.
“A key part of this specification includes the definitions for signaling 3-D content over existing digital video infrastructure that uses either MPEG-2 or MPEG-4 coding,” said Jim Occhiuto, vice president of technology and engineering at Showtime Networks. “This signaling is critical for the receiver/decoder to enable automatic format detection and simplified user experiences when going between 2-D and 3-D programs.”
The CableLabs 3-D content specification was developed with support from cable operators, programmers and equipment vendors and is freely available. It replaces the previous VOD-Content Encoding Profile 2.0 specification that has been widely adopted within the industry.
The specification represents the first step in a continuing process to define 3-D formats for cable TV that works with existing equipment and infrastructure. Work continues at CableLabs on the development of standards for the delivery of future 3-D delivery systems that will expand the resolution and the quality as new equipment becomes available.
