The AGOTTVS group has requested that the AES Standards Committee consider elevation of TD1006: Loudness Guidelines for OTT and OVD Content (Oct 2017) to an AES Standard, Recommended Practice.
This work has been assigned to the Task Group SC-02-12-P led by Jim Starzynski. The new document scope is:
This AES document addresses OTT and OVD Loudness challenges by leveraging already established Over-the-Air Television practices, providing new guidelines focused on the Loudness and Content Dynamic Range for connected set-top and mobile devices. When followed, these guidelines will:
· Provide consistent Loudness across different Programs, service providers and advertising Content
· Provide appropriate playback Loudness Range for different devices and listening conditions
· Prevent excessive Peak Limiting or other processing from degrading the audio quality
· Preserve the artistic intent of wide Content Dynamic Range (movies, drama, live music)
· Improve the listening experience
Interested parties are invited to download the original Technical Council document, review it and send their comments to the Task Group chair. Interested individuals are also encouraged to participate in the groups work.

The standards work of the Audio Engineering Society has been vital to the advancement of the audio industry. Numerous standards in development are driving an expansion of the AES standards operation. That necessitates an expanded base of funding. Unlike other technical societies with standards programs the AES does not charge participation fees. The Society believes that a completely open process ultimately produces better and more widely accepted standards. Consequently other sources of revenue are required.
The AES Standards Committee is soliciting industry support through a new program called "AES Standards Sustainers". Besides enabling the development of standards that underlie fundamental technology in the audio industry, the program offers participants significant marketing and public relations exposure. The Audio Engineering Society is a 501(c)(3) nonprofit organization and 100% of the contribution is tax deductible to the fullest extent of the law.
Donors may contribute at four different levels; a $1,000 basic level, $2,000 Silver level, $5,000 Gold level or a $10,000 Platinum level.
Founding Standards Sustainers include Netflix as a Standards Sustainer Gold, Eventide, Coveloz, Adamson Systems, The Telos Alliance, and Audio Precision as Silver Sustainers.
Founding Standards Sustainers also include Audyssey Laboratories, NTi Audio, MQA Ltd., KLIPPEL GmbH, Clair Global, Fraunhofer IIS, Audio Technica, NBC Universal, Metric Halo, Dolby Laboratories Inc., and USound GmbH.
All Standards Sustainers will have their contributions recognized on the inside covers of all AES Standards beginning July 1, 2017. Details on participating in the Standards Sustainer program may be found at the link below.

This report, AES-R17-2017, summarizes the AES67 interoperability test event ("plugfest") held at the headquarters of British Broadcasting Corporation (BBC), London on 13 to 16 February 2017. Twenty four companies tested 36 products against each other to confirm interoperability. The results are presented, together with the results of a range of tests of optional operational modes described in the standard.
The purpose of the plugfest was to demonstrate functional compatibility and interoperability between a number of different implementations of the standard AES67-2015, "AES standard for audio applications of networks - High-performance streaming audio-over-IP interoperability".
One goal was to achieve interoperability success between nodes from different vendors based on the current AES67 standard definitions. Another major goal was to identify ambiguities and shortcomings of the current standard definitions to be addressed in a revision of the AES67-2015 standard. The plugfest was not intended to verify full compliance to all requirements of the standard for each device under test.
This report follows the same pattern as the AES-R12 report of the 2014 AES67 plugfest, held in Munich and the AES-R15 report of the 2015 AES67 plugfest, held in Washington D.C.

AES67-2015, AES standard for audio applications of networks - High-performance streaming audio-over-IP interoperability has been translated into Chinese and published by the China State Administration of Press, Publication, Radio, Film and Television. Its publication is indicative of the wide acceptance of the AES-67 standard in professional and broadcast audio applications world wide.
This is the culmination of work begun in early 2016 by China National Radio, China Central Television, China Academy Of Broadcasting Science, China State Administration of Press, Publication, Radio, Film and Television, China Academy Of Broadcasting Planning, Suzhou Fortune Technology Co., Ltd., Digital Media Technology Co., Ltd., and Hanzhou Linker Technology Corporation.

The AES is pleased to announce that Dr. Richard C. Cabot will be assuming the duties of Standards Manager. A former President of the AES, he has been involved with AES Standards since its early years, having chaired the development of the AES17 standard on digital audio measurement. He was one of the founders of Audio Precision, and developed their digital audio measurement technology. In addition to his standards work, Dr. Cabot's company, XFRM, Inc., designs professional audio equipment, consults on Intellectual Property patentability and infringement issues, and evaluates technology to guide companies in their investment decisions. He noted "I'm excited by the opportunity to guide AES Standards development going forward".
Mark Yonge, standards manager since 2001 has announced his intention to retire after the Berlin convention. During Mark's 16 years in the post he has expertly shepherded dozens of standards through the process from initial concept to published document. Under his guidance the AES Standards organization has grown to become the premier venue for coordinating technology in the audio field. Mark commented that, "it will be a wrench to step aside from the work of audio standards development, but I am delighted that Rich is taking up the task."
Please join me in welcoming Rich to his new role, and I know you will assist him in the coming transition. Until the AES 142nd convention there will be a transitional overlap period when Mark and Rich will be working together.
I look forward to seeing you at our standards meetings in Berlin at the AES 142nd Convention.
AES Standards Committee Chair.

AES and SMPTE have both specified profiles for IEEE 1588-2008 Precision Time Protocol (PTP) for use in professional media applications; the respective standards being AES67 and SMPTE ST 2059-2. The design goals were somewhat different: the AES standard was aimed at interoperability of some existing networked audio systems and the SMPTE standard at meeting requirements of the EBU/SMPTE Task Force on Timing and Synchronization. Nevertheless, it is clear that there is significant overlap in the application space and that some users will want to use equipment conforming to AES and SMPTE specifications on the same network and in the same PTP domain.
Each standard defines a profile in terms of ranges and recommended default settings for parameters. The requirements of the two standards are not mutually exclusive and this report explores suitable parameter choices for interoperation. The overlapping operating conditions identified in this document are not intended to replace any profile, but rather to identify a common set of parameters and options that satisfy multiple applications.
This document is based on a reading of the two standards and the knowledge that interoperation was a stated development goal for both AES and SMPTE. Further experience with interoperation of these profiles may lead to revisions of this document or one or both of the involved standards.
