ATSC Ratifies Three More ATSC 3 Standards Suite Components

October 5, 2016 by Diana Marszalek Leave a Comment

ATSC 3.0Three more standards making up the ATSC 3.0 suite of next-gen TV standards — one that links the physical layer to the network layer and one each pertaining to audio and video watermarking — have been ratified, the Advanced Television Systems Committee said today.

Separately, three new Proposed Standards and two Candidate standards are advancing through the technical subcommittee responsible for the overall standard, ATSC said.

The three newly approved ATSC 3.0 standards are:

  • A/330 — The Link Layer Protocol Standard, which defines the layer between the physical layer and the network layer. The link layer transports the data from the network layer to the physical layer at the sending side and transports the data from the physical layer to the network layer at the receiving side.
  • A/334 — The Audio Watermark Emission Standard, which specifies the audio watermark encoding to be used.
  • A/335 — The Video Watermark Emission Standard, which lays out the emission format for the video watermark.

“The three new standards join two others (the A/322 Physical Layer and A/321 System Discovery and Signaling standards) already approved by ATSC members,” said ATSC President Mark Richer.

Voting among members of the ATSC Technology Group 3 (TG3) has begun to elevate three ATSC Candidate Standards to Proposed Standard status. They include: A/322 Service Announcement, A/333 Service Usage Reporting and A/343 Captions and Subtitles.

According to Richer, “other parts of ATSC 3.0 are rapidly moving through the standardization process.” When complete the ATSC 3.0 suite of standards will consist of about 20 separate standards.

More information is available on the ATSC website.
