ATSC Expanding Video Compression Options for ATSC 3.0

WASHINGTON — The Advanced Television Systems Committee (ATSC), the broadcast standards association, is working to add the international video compression method Versatile Video Coding (VVC) as an option in addition to the High Efficiency Video Coding (HEVC) technology used in the current roster of ATSC 3.0 broadcast standards. Even more efficient than current methods, VVC could provide a path to 8K broadcasting via ATSC 3.0 and might also be utilized to efficiently deliver broadcast video services while simultaneously conserving bandwidth.

“Since the first work began on the third-generation of the ATSC broadcast standard, we’ve considered ATSC 3.0 to be a suite of global technology standards that could evolve and be easily adapted for new technology developments. The rigid parameters of the original ATSC 1.0 standard in the 1990s led to the development of a more flexible system that we utilize today,” said ATSC President Madeleine Noland.

As an ATSC “Candidate Standard,” VVC is currently being evaluated as a possible additional advanced compression system for ATSC 3.0.

“Later this year, ATSC members expect to vote to elevate the VVC Candidate Standard to a full Standard, which will make this new codec part of the ATSC 3.0 suite of nearly 20 standardized options for broadcast delivery of data. ATSC adds new technologies to add value to the standards suite, to enable future deployment, and to adapt to regional needs. The addition of VVC makes ATSC 3.0 even more appealing for adoption internationally and is not expected to impact U.S. broadcasters or viewers in the near term. Over time, this standardization effort helps guide integration of VVC into future devices,” Noland explained.

VVC has been standardized for other types of media delivery, outside of broadcasting, and could be used for delivery of niche or private video services. The VVC compression standard is recognized by cable operators and also in other countries outside of the U.S. Brazil has indicated, as an example, that it intends to utilize VVC for its video base layer, as part of its “TV 3.0” initiative that is now in development.

“We believe it’s important for ATSC to continue to innovate and take full advantage of the latest technology developments, which is why members are interested in adding VVC to ATSC 3.0. We want to make certain that ATSC 3.0 is well positioned for the future, and we look forward to continued progress during the Candidate Standard evaluation period that will culminate with VVC being considered as a full ATSC 3.0 Standard,” Noland added.
