Washington, DC (September 14, 2016)—The Advanced Television Systems Committee (ATSC) members have approved the Physical Layer transmission system for ATSC 3.0 next-generation television broadcasting as a Final Standard by ballot, signaling that the standardization process for the entire ATSC 3.0 process is nearing completion.

“The hundreds of technology experts from around the world who have contributed their time and expertise to this process have selected the best and most flexible transmission system as the foundation of ATSC 3.0. While other ingredients of the ATSC 3.0 standard are still in the final stages of standardization, the approval of the over-the-air transmission system is a foundation for the future,” said Mark Richer, president, ATSC.

The new ATSC 3.0 Physical Layer (ATSC A/322) allows television broadcasters to choose from a wide variety of transmission parameters so that each station can tailor its signal to best serve its local market by providing the combination of services and coverage area best suited for the market and its terrain. Key capabilities of the ATSC 3.0 Physical Layer include use of Single Frequency Networks, multiple physical layer pipes and channel bonding. Selected technologies allow for data transmission with a wide range of guard intervals, forward error correction code lengths and code rates.

Work continues apace on the other elements of the suite of approximately 20 ATSC 3.0 standards. Earlier this year, the A/321 System Discovery and Signaling (colloquially called “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.

These Proposed and Candidate Standards will include video and audio compression, high dynamic range (HDR), wide color gamut and immersive sound, closed captioning, advanced emergency alerting, security, companion devices, personalization, applications & interactivity, watermarking & fingerprinting, and Internet Protocol delivery.
