ATSC 3.0 Physical Layer Standard Approved

“We’re likely to see both 4K Ultra HD broadcasts running side-by-side with robust mobile broadcasts to handheld devices, thanks to the innate flexibility of ATSC 3.0’s Physical Layer. The system will allow high-capacity modes when stunning video is more important. And it also permits lower-capacity transmissions with extremely high robustness for receivers on the go,” Richer said.

The ATSC said final approval of the A/322 Physical Layer standard reflected the momentum behind next-gen TV. Work continues apace on the other elements of the suite of ATSC 3.0 standards. In March of this year, the A/321 System Discovery and Signaling (the “bootstrap”) part of the Physical Layer was standardized, and a number of other ATSC 3.0 standards are nearing the conclusion of the standardization process. (See, “First Element of ATSC 3.0 Approved for Standard,” March 28, 2016.)

These Proposed and Candidate Standards will include Video and Audio Compression, high dynamic range, wide color gamut and immersive sound, closed captioning, advanced emergency alerting, security, companion devices, personalization, applications and interactivity, watermarking and fingerprinting, and Internet Protocol delivery.

All told, some 20 standards are expected to be part of the final ATSC 3.0 suite of standards by early next year.
