The Advanced Television Systems Committee (ATSC) has standardised three more components of the next-generation television system that is expected to transform the ability of broadcasters to deliver mobile, interactivity and higher quality content.
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 the technical subcommittee 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 broadcast content. These are each important elements that will give ATSC 3.0 remarkable flexibility. The three new standards join two others (the A/322 Physical Layer and A/321 System Discovery and Signalling standards) already approved by ATSC members. Other parts of ATSC 3.0 are rapidly moving through the standardisation process,” said ATSC President Mark Richer.
Technical details on the three newest ATSC 3.0 standards:
This week, ATSC Technology Group 3 (TG3) members have begun voting to elevate three ATSC Candidate Standards to Proposed Standard status (the final step before ATSC member approval):
TG3 members also are voting to elevate the A/360 Security draft document to Candidate Standard status. A/360 specifies the mechanisms for security and service protections in ATSC 3.0 systems. The A/324 Scheduler and Studio-to-Transmitter Link is now a Candidate Standard. Among other things, it specifies the interface protocol and operation parameters for Single Frequency Network transmitters.
