ATSC Standard A/52:2018 ATSCA/52:2018 Digital Audio Compression (AC-3, E-AC-3) 25 January 2018 ATSC Standard: Digital Audio Compression (AC-3, E-AC-3) Doc. A/52:2018 25 January 2018 Advanced Television Systems Committee 1776 K Street, N.W. Washington, D.C. 20006 202-872-9160 i ATSCA/52:2018 Digital Audio Compression (AC-3, E-AC-3) 25 January 2018 The Advanced Television Systems Committee, Inc., is an international, non-profit organization developing voluntary standards for digital television. The ATSC member organizations represent the broadcast, broadcast equipment, motion picture, consumer electronics, computer, cable, satellite, and semiconductor industries. Specifically, ATSC is working to coordinate television standards among different communications media focusing on digital television, interactive systems, and broadband multimedia communications. ATSC is also developing digital television implementation strategies and presenting educational seminars on the ATSC standards. ATSC was formed in 1982 by the member organizations of the Joint Committee on InterSociety Coordination (JCIC): the Electronic Industries Association (EIA), the Institute of Electrical and Electronic Engineers (IEEE), the National Association of Broadcasters (NAB), the National Cable & Telecommunications Association (NCTA), and the Society of Motion Picture and Television Engineers (SMPTE). Currently, there are approximately 140 members representing the broadcast, broadcast equipment, motion picture, consumer electronics, computer, cable, satellite, and semiconductor industries. ATSC Digital TV Standards include digital high definition television (HDTV), standard definition television (SDTV), data broadcasting, multichannel surround-sound audio, and satellite direct-to-home broadcasting. NOTE: The user's attention is called to the possibility that compliance with this standard may require use of an invention covered by patent rights. By publication of this standard, no position is taken with respect to the validity of this claim or of any patent rights in connection therewith. One or more patent holders have, however, filed a statement regarding the terms on which such patent holder(s) may be willing to grant a license under these rights to individuals or entities desiring to obtain such a license.

A/52B 14 June 2005 Revision B corrected some errata in the detailed specifications, and added a new annex, then titled “Enhanced AC-3 Bit Stream Syntax” which specified a non-backwards compatible syntax that offers additional coding tools and features. Informative references were removed from the body of the document and placed in a new Annex B. This version added new definitions for terms such as “frame” and “synchronization frame” that extended their original meanings without clearly noting the extensions. A/52:2010 22 November 2010 The 2010 revision of this standard restored the document structure to place the Scope as Section 1, restored Informative References, and made significant adjustments to Annex A in response to a request from CEA to clarify the semantics for AC-3 Elementary Streams in the MPEG-2 TS. Minor textual adjustments were made in as well. A/52:2012 23 March 2012 The 2012 revision of this standard changed the title of Annex E from “Enhanced AC-3 (E-AC-3) Bit Stream Syntax” to “Enhanced AC-3.” In addition, it added two new Annexes, Annex F titled “AC-3 and Enhanced AC-3 bit streams in the ISO Base Media File Format” and Annex G titled “Enhanced AC-3 Elementary Streams in the MPEG-2 Multiplex “(intended to match Annex A in structure and scope). It also clarified the “overloaded” terms added in Revision B; e.g., older versions of this standard used the terms “frame,” “synchronization frame” and “syncframe” interchangeably and had the same meaning. Subsequently the term “audio frame” was added and has a different meaning thus addressing some issues left by Revision B. Note: An updated version of this document was published on 17 May 2012 that corrected prefix letters in the table of contents. Corrigendum No. 1 17 December 2012 This corrigendum addresses service_type term overload by renaming the field in A/52 Annex G to audio_service_type. A/52:2015 24 November 2015 This revision added documentation for all of the audio service types matching the signaling in the “bsmod” data field, as well as documenting the use of an optional new structure defined by ETSI. A/52:2018 25 January 2018 This revision was developed to address various errata, update the external references as needed, and perform editorial updates as needed. The revision also expands Annex H to add a citation to the new ETSI TS 103 420 (“Backwards-compatible object audio carriage using Enhanced AC-3”). iii ATSCA/52:2018 Digital Audio Compression (AC-3, E-AC-3) 25 January 2018 Table of Contents 1.

  • Ensuring PMCP/PSIP Interoperability
    June 30, 2008 Ensuring PMCP/PSIP Interoperability Recognizing the need for improved industry-wide PMCP interoperability, and thus more accurate PSIP, the ATSC has formed a new Working Group on PSIP Workflow Interoperability, PC-7. This group, reports to the ATSC’s Planning Committee and is chaired by Chris Lennon of Harris Corporation, who provided this contribution to TV TechCheck. For those not familiar with it, PMCP (ATSC Standard A/76B) is the Programming Metadata Communication Protocol. It provides a standardized means of communicating PSIP-related data among the systems that manage it. PMCP has been around for some time, and has recently enjoyed a significant uptake in the industry as interest in and awareness of the need for dynamic, accurate PSIP increases. Part of the scope of the ATSC Planning Committee is to “support the use of ATSC standards and recommended practices through activities such as education, training, demonstrations and fostering interoperability.” The goal of the PC-7 Working Group is to assemble a group of broadcasters and vendors who are implementing (or plan to implement) dynamic PSIP by way of PMCP interfaces between systems such as listing services, program management, traffic, automation, and PSIP generator systems. The group will work to improve interoperability of these systems by way of information exchange regarding PMCP and implementation issues, both on regular conference calls, and at one or more in-person interoperability sessions in Toronto in late Fall 2008. The PC-7 Working Group hopes to provide members a forum in which vendors and broadcasters can work out interoperability details in an open, cooperative environment, benefiting not only the vendors, but the broadcasters who will be implementing these interfaces.

(“Sinclair”) (Nasdaq: SBGI) and ONE Media 3.0, LLC (“ONE Media”) applaud the Telecom Standards Development Society, India (TSDSI) and the Advanced Television Systems Committee (ATSC) for signing an agreement to enable adoption of ATSC standards for broadcast services on mobile devices in India. As members of both standards organizations, Sinclair and ONE Media have actively supported co- operative efforts between TSDSI and ATSC on this agreement as well as detailed standards contributions and joint U.S. and Indian activities. Of particular significance, ATSC 3.0, the world’s first Internet-Protocol-based television broadcast standard, has many elements of convergence and compatibility with international telecom standards that have been recognized by this agreement as a strong candidate for Direct-to-Mobile broadcast for the billion strong mobile user base in India. Developed by the Advanced Television Systems Committee, the ATSC 3.0 standard has been adopted in both the United States and the Republic of Korea. Unlike other digital terrestrial broadcast standards including the European DVB-T, Japanese/Brazilian ISDB-T, and Chinese DTMB platforms, it is purpose-built for the modern 5G telecom era of convergence with the ability to introduce new waveforms and features for rapidly evolving use cases. “We’re delighted that leaders in broadcast and telecom standards are charting a way forward to break traditional walls between these verticals in the interest of creating the most cost-effective broadcast solution for massive cellularized deployment.

No part of this publication may be reproduced, by any means whatsoever, without the prior written permission of ITU. Handbook on digital terrestrial television broadcasting networks and systems implementation iii Editors’ Foreword In 2002 ITU published its first Handbook on digital terrestrial television under the title Digital terrestrial television broadcasting in the VHF/UHF bands1 as guidance to engineers responsible for the implementation of digital terrestrial television broadcasting (DTTB). In the Handbook, new digital broadcasting technologies were explained in detail, for example a splendid description of the Discrete Cosine Transform (DCT) coding that is the basis of all past and present TV compression systems, as well as a very instructive chapter on signal power summation. Most of that content are not repeated in this new Handbook on digital terrestrial television broadcasting networks and systems implementation. Therefore, the version 1.01, which was published by ITU in the year 2002, has not lost value and should still be consulted. Since 2002, DTTB has tremendously evolved, not only in technical but also in regulatory aspects. For example, at the turn of the century, MPEG had just started to develop the compression scheme MPEG-4, and HEVC was not known at all. In two sessions, in 2004 and 2006, the important ITU Regional Radiocommunication Conference RRC-06 was held in Geneva and agreed a new frequency plan for digital broadcasting in Region 1 (except Mongolia) and in Iran.
