ATSC Standards Update: Four Updated Documents Published

Posted on December 16, 2022 in ATSC News

Four updated documents have been published on the ATSC website since the last issue of The Standard:

• A/322:2022-11, “ATSC Standard: Physical Layer Protocol.” This version includes an amendment that clarifies time expressions and references.
• A/327:2022-12, “ATSC Recommended Practice: Guidelines for the Physical Layer Protocol.” This version includes anamendment that added an Annex documenting issues identified in fielded receivers. Certain performance issues in fielded ATSC 3.0 receivers have been observed, and the listing of these issues—along with potential solutions that broadcasters can adopt to avoid the issues’ occurrence—can be useful to optimize the user experience of consumers who own such receivers.
• A/331:2022-11, “ATSC Standard: Signaling, Delivery, Synchronization, and Error Protection.” This version includescorrections and clarifications to the protocol for interaction between an ATSC receiver and a broadband signaling server.
• A/360:2022-11, “ATSC Standard: ATSC 3.0 Security and Service Protection.” This version removes references to CTA 2053, which has been withdrawn by CTA.

The ATSC workspace system (Kavi) sends out a notification to members when each ballot opens. Reminders are sent to members who have not already voted one week before the ballot closes, and again one business day before the ballot closes. After a ballot has closed, voting details are available to members of the group. Comments submitted during the ballot period also may be viewed. Notification of a closed ballot and the results of that ballot are sent to members on the business day following closure by ATSC staff.
