ATSC 3.0

A/330, “Link-Layer Protocol”

Posted on October 3, 2016 in

This standard defines the ATSC Link-Layer Protocol (ALP). ALP corresponds to the data link layer in the OSI 7-layer model. ALP provides a path to deliver IP packets, link layer signaling packets, and MPEG-2 Transport Stream (TS) packets down to the RF Layer and back, after reception. ALP also optimizes the proportion of useful data […]

A/322, “Physical Layer Protocol”

Posted on October 3, 2016 in

This Standard describes the RF/Transmission of a physical layer waveform. This waveform enables flexible configurations of physical layer resources to target a variety of operating modes. The intent is to signal the applied technologies and allow for future technology adaptation. Download current version: A/322:2024-09, “Physical Layer Protocol”, 13 September 2024. Previous Versions There are multiple […]

A/335, “Video Watermark Emission”

Posted on September 13, 2016 in

The video watermark technology described in this document provides the capability to robustly embed ancillary data in the transmitted pixels of a video signal. It is intended to provide a data path for its ancillary data payload that can readily survive changes in video compression data rate, transcoding to other video compression codecs, and delivery […]

A/334, “Audio Watermark Emission”

Posted on September 13, 2016 in

This document specifies the VP1 audio watermark for use with systems conforming to the ATSC 3.0 family of specifications. The document specifies the format in which the audio watermark resides in a PCM audio signal. Emission by a broadcaster of the audio watermark is optional. Download current version: A/334:2024-04, “Audio Watermark Emission”, 3 April 2024. This […]

A/321, “System Discovery and Signaling”

Posted on March 24, 2016 in

This document describes the system discovery and signaling architecture for the ATSC 3.0 physical layer. Broadcasters anticipate providing multiple wireless-based services, in addition to conventional broadcast television in the future. Such services may be time-multiplexed together within a single RF channel. The bootstrap provides a universal entry point into a broadcast waveform. The bootstrap employs […]
