Since the last issue of The Standard newsletter, one new document has been published on the ATSC web site — A/345:2023-11, “VVC Video Candidate Standard.” A Candidate Standard (CS) is a document that has received significant review within a Specialist Group. Advancement of a document to Candidate Standard is an explicit call to those outside of the related Specialist Group for implementation and technical feedback. This is the phase at which the Specialist Group is responsible for formally acquiring that experience or at least defining the expectations of implementation.
A/345 describes the video coding constraints on ITU-T Rec. H.266 | International Standard ISO/IEC 23090-3 (“VVC”) when it is used for video compression in the ATSC 3.0 Digital Television System. Any other video coding technologies in the ATSC 3.0 system are documented in their own ATSC Standard(s). ATSC A/300, “ATSC 3.0 System,” provides references to the various video coding technology document(s) in the ATSC 3.0 system. Signaling of the video compression technology in use is defined in ATSC A/331, “Signaling, Delivery, Synchronization, and Error Protection.”
A Candidate Standard may be updated from time to time by the originating Specialist Group, in this case TG3/S41. The A/345 CS period extends to 30 June 2024. The CS period may be shortened or extended by TG3.
Voting is an important element of membership in ATSC. All Standards, Candidate Standards, and Recommended Practices must be approved via one or more ballots, conducted on the Causeway workspace. Online voting is easy, but we sometimes receive questions about certain elements of the process; for example, how the Primary/Alternate voter protocols work. Details are as follows:
It is important for Voting Members of the ATSC to participate in ballots. Every ballot on a given document provides three options: Yes, No, or Abstain. Because there are minimum participation requirements for Technology Group and Membership ballots, all members are urged to carefully consider each ballot and vote accordingly. There may be instances where a member has no opinion on the question presented in the ballot. In that case, an Abstain vote may be cast. This is important, since Abstain votes count toward meeting the minimum participation requirements. ATSC staff is always available to answer any questions that members may have on voting.
