Balloting Begins on ‘Main Elements’ of ATSC 3.0's Physical Transmission System
Balloting began this week on the “main elements” that will compose ATSC 3.0's physical transmission system, ATSC President Mark Richer said Wednesday in ATSC’s monthly newsletter, The Standard. If approved, those elements will be elevated to the status of a…

candidate standard, he said. That's significant because it will provide “a strong foundation for the industry to begin considering the launch of next-generation television broadcasting,” and will help “kickstart manufacturers to begin developing prototype ATSC 3.0 equipment,” he said. Within a month, ATSC will have a complete physical layer that manufacturers can start building to, ATSC insiders told us. The expectation is that perhaps as early as CES in January, the industry will have prototype physical devices for ATSC 3.0's transmission system available to the market, they said. ATSC will make an announcement when the ballot is voted and it’s expected that the vote on the system will pass because the companies that were involved in harmonizing ideas around a physical transmission system agreed the industry now has something that’s ready to be built, they said. CEA’s R4WG18 working group created a “gap analysis” of current and proposed ATSC 3.0 video formats for over-the-air broadcast and broadband streaming video “use cases,” said Brian Markwalter, CEA senior vice president-research and standards, in the same issue of the newsletter. From that gap analysis, R4WG18 recently reached consensus “on a lower limit for video formats that should be supported by ATSC 3.0 receivers, primarily fixed, larger screen devices, for the OTA use case,” he said, referring to over-the-air broadcasts. “With some yet-to-be-determined details, an initial list of broadband video formats has also been proposed.” The first section of the recommended practice will focus on recommended video formats for “baseline” and “advanced” fixed TVs, he said. “The final document is expected to address the audio, runtime and other aspects of both baseline and advanced ATSC 3.0 receivers.” R4WG18 hopes to complete the video formats list and give CEA’s R4 video systems committee a “progress report” at face-to-face meetings this month, he said.
