Comment Resolution Underway on First ATSC 3.0 Candidate Standard

Posted on June 3, 2015 in ATSC News

The first Candidate Standard approved for ATSC 3.0 (A/321 System Discovery and Signaling), has moved into the comment resolution phase in the S-32 specialist group. This so-called “bootstrap signal” portion of the Physical Layer will be important to the future evolution of ATSC 3.0. Updates to the published Candidate Standard are expected in a timely manner, possibly later this month.

Elsewhere in the TG-3 Technology Group driving the ATSC 3.0 process, work is continuing to wrap-up a number of key Working Draft documents in preparation for TG-3 ballots to be elevated to Candidate Standard status during the summer months.

In other ATSC standards news, two new standards from the TG1 Technology Group have been approved by the membership and are now published.

• A/72 Part 1:2015 (Video System Characteristics of AVC in the ATSC Digital Television System) describes the video encoding constraints on ITU-T Rec. H.264 (“AVC”) video compression in the ATSC Digital Television System.

• A/78:2015 (Recommended Practice: Transport Stream Verification) provides a common methodology for describing Transport Stream conformance criteria. This recommended practice explicitly describes the elements and parameters of A/53 and A/65 that should be verified in an ATSC Transport Stream for it to be considered a proper emission.

In addition to these newly-approved revisions, two other membership ballots are currently open on new documents that are part of the ATSC 2.0 suite of backward-compatible enhancements to the current standard: A/106 (ATSC Security and Service Protection Standard) and A/107 (ATSC 2.0 Standard). These membership ballot items are set to close in mid-June.
