ATSC 3.0 Standards


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 […]

A/330:2016, Link-Layer Protocol

Approved 19 September 2016

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/334:2016, “Audio Watermark Emission”

Approved 19 September 2016

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.

A/335:2016 “Video Watermark Emission”

Approved 20 September 2016

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 over […]

This document specifies methods by which receivers may recover content that is available from a broadcaster, but not delivered directly to the receiver through the RF broadcast signal. This method may be useful in the use case when the receiver is connected to a set-top box via an HDMI cable and is only receiving uncompressed […]

A/338:2017, “Companion Device”

Approved 17 April 2017

This document specifies the communication protocol between an ATSC 3.0 primary device and an ATSC 3.0 companion device. In this context, the primary device is the primary receiver and is used to present the primary content. The companion device communicates with the primary device to present related, supplementary content, or even the same content as […]

A/342 Part 2:2017, “AC-4 System”

Approved 23 February 2017

This document standardizes the AC-4 audio system for use in the ATSC 3.0 Digital Television System. It describes the characteristics of the AC-4 audio system and establishes a set of constraints on ETSI TS 103 190-2 for use within ATSC 3.0 broadcast emissions. The ATSC 3.0 audio system provides an enhanced feature set and improves […]
