CTA’s Markwalter Won’t ‘Speculate’ When 3.0 Receiver Practices Will Be Complete

The ATSC 3.0 receiver “guidelines work” that CTA is conducting “is an open standards project,” Brian Markwalter, CTA senior vice president-research and standards, emailed us. “The working group, under our Video Systems Committee, develops recommended practices for ATSC 3.0 receivers (mirroring ATSC’s work on ATSC 3.0),” he said. “The recommended practices are being developed as a suite.” Documents addressing the physical layer, logical layer, video and audio are complete, and “others are in process,” he said. “We do not speculate on the schedule” for when work on the entire suite will be finished, he said. Markwalter, an ATSC board member, said in the fall the “pace of work” was accelerating on the CTA-CEB32 “family” of recommended 3.0 receiver practices that would consist of 11 parts plus an overview that will be “easily mapped” to the suite of 3.0 standards (see 1709050038). CTA “has an associated group, where they’re writing recommendations” for 3.0 receivers, said Winston Caldwell, Fox Networks Group vice president-spectrum engineering and advanced engineering, at an NAB Show workshop on maximizing 3.0's future business potential (see 1804100048). “We’ve been involved there just to make sure that those receivers support a lot of the capabilities that we’re interested in.”
