Advanced Television Systems Committee Approves New Standard
WASHINGTON, D.C., September 15, 2008 – The Advanced Television Systems Committee, Inc. has approved and published A/72 which details the methodology to utilize Advanced Video Coding (AVC) within an ATSC DTV transmission. AVC which was developed by the ITU-T Video Coding Experts Group together with the ISO/IEC Moving Picture Experts Group is also known as H.264 and MPEG-4 Part 10. The A/72 Standard defines constraints with respect to AVC, compression format restraints, low delay and still picture modes, and bit stream specifications. In addition it specifies how CEA-708 closed captions are to be carried in an AVC bitstream. The new standard is in two parts, Part 1 is titled “Video System and Characteristics of AVC in the ATSC Digital Television System,” and “Part 2 “AVC Video Transport Subsystem Characteristics.”
“AVC compression provides increased efficiency and flexibility”, said ATSC President Mark Richer. “The new standard will be especially important for those countries which have not yet implemented digital television. AVC will also be used with standards in development such as ATSC-M/H for mobile and handheld applications and ATSC-NRT for non-real-time delivery of programming.”
The Advanced Television Systems Committee is an international, non-profit organization developing voluntary standards for digital television. The ATSC member organizations represent the broadcast, broadcast equipment, motion picture, consumer electronics, computer, cable, satellite, and semiconductor industries. ATSC creates and fosters implementation of voluntary Standards and Recommended Practices to advance terrestrial digital television broadcasting, and to facilitate interoperability with other media.
ATSC-M/H is being developed to support a variety of services including free (advertiser-supported) television and interactive services delivered in real-time, subscription-based TV, and Non-real-time content download for playback at a later time. The standard may also be used for transmission of new data broadcasting services such as real-time navigation data for in-vehicle use.
ATSC-NRT addresses the new reality that consumers are increasingly in control and want information and entertainment content, when and where they want it. By leveraging the low cost of storage in receivers, broadcasters utilizing the ATSC-NRT Standard will be able download content to a new generation of products.
ATSC-2.0 will define a complete suite of “Next Generation” services for the conventional fixed DTV receiver viewing environment.
