ATSC members have ratified the Link Layer Protocol and Audio and Video Watermark Emission standards to be part of the ATSC 3.0 suite of 20 standards and recommended practices. At the same time, three new Proposed Standards and two new Candidate Standards are moving forward within TG3, the ATSC Technology Group charged with developing and documenting ATSC 3.0.
“The latest ATSC 3.0 standards will help future devices transport incoming data and provide for both audio and video watermarks in future content broadcasts. These are each important elements that will give ATSC 3.0 remarkable flexibility,” says ATSC President Mark Richer.
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. Other parts of ATSC 3.0 are “rapidly moving through the standardization process,” Richer adds, highlighting the technical details on the three newest ATSC 3.0 standards:
TG3 just approved the Scheduler and Studio-to-Transmitter Link (STL) Candidate Standard (A/324). This standard specifies the protocol on the Studio to Transmitter Link (STL) interface from studio side infrastructure to transmitters (including Single Frequency Networks (SFN)). It also defines possible interfaces among the studio infrastructure, specifies certain constraints on the scheduling of content and signaling on the physical layer, and describes controlling transmitter operation parameters with protocols over an STL.
In October, TG3 members are voting to elevate three ATSC Candidate Standards to Proposed Standard status:
Another new TG3 ballot would move the A/360 Security draft document to Candidate Standard Status. This document specifies the mechanisms for security and service protections in ATSC 3.0 systems.
