Projects assigned to this group but not mentioned here had no action requested or required - see www.aes.org/standards/meetings/project-status.cfm for details.
AES67-R - Review of AES67-2018 , AES standard for audio applications of networks - High-performance streaming audio-over-IP interoperability
AES70-1-R Review of AES70-1-2018: AES standard for audio applications of networks - Open Control Architecture - Part 1: Framework
AES70-2-R Review of AES70-2-2018: AES standard for audio applications of networks - Open Control Architecture - Part 2: Class structure
AES70-3-R Review of AES70-3-2018: AES standard for audio applications of networks - Open Control Architecture - Part 3: Protocol for TCP/IP networks
AES-X242 Streaming audio metadata over IP
AES-X243 Using AES70 connection management for AES67
AES-X251 AES74 Conformance Survey
Liaison with MPEG (John Grant)
Nothing new to report.
Liaison with mobile (John Grant)
Reporting on ETSY: NGP (Next Generation Protocols) now finished. As the group concluded that IP was not the way to go, a new group called Non IP Networking has been formed.
There are currently 19 member organizations, writing 3 documents.
The first one setting up the problem, the second one talking about how to do it over wireless (reliable delivery, low latency etc.) , and the last one is the network model setting the ‘mathematical axioms’ so to speak.
The goal is to be able publish these 3 documents before the end of this year and then start prototyping appropriate technology and test it out, starting by the end of the year.
Would welcome participation from anyone who is interested.
Liaison with AMWA (Anthony Kuzub)
Working on NMOS, involved in study creating profiles for equipment. Aim to find a generic way to describe the behavior of a device as it behaves within a certain family or class. This is the very same effort referenced above under AES70 in relation to NMOS.
Liaison with IEC62379-1 (Common control interface, orig. BBC project in 2004, ATM etc.) (Peter Stevens)
There may well be some amendments but then it will likely be stored away.
ST 2059 (Use of PTP for professional media sync.) (Paul Treleaven)
The use of the two parts -1 and -2 are getting close to being published as a revision, it has taken a long time. The good news is that it is close to being published. However, the base standard IEEE 1588 has undergone some major changes which will be published as version 2.1. The next big job for ST 2059 will be to incorporate those changes.
Liaison with Avnu ProAV AVTP (Morten Lave)
The Milan standard is published, it is an interoperability standard for pro-audio over AVB.
A test specification is also released.
Work is currently being done on the next version of the test specification.
The next meeting will be scheduled in conjunction with the AES 149th Convention, to be held online in October 2020
