IABM Report and Executive Summary from the AES May 2018 Standards Meetings

The AES standards meeting round is held in conjunction with each of its two annual conventions (one in Europe, one in the USA). This convention was held in Milan, 23 26 May.

The IABM has produced a report of the meetings that can be downloaded from this webpage (member login required). Below is a short Executive Summary of the meeting round.

The most important work, as far as most IABM members will be concerned, is all in the Audio Applications of Networks working group:

AES67 related projects. A new revision of AES67 was published in April 2018. It incorporated issues that had been identified at AES67 plugfests as well as implementation problems that had been reported. The main change was the addition of a Protocol Implementation Conformance Statement (PICS) as Annex G. It is a large table that allows a simple YES / NO answer for all of the conformance statements in AES67. It differentiates the mandatory and optional requirements. The AES67 group continues to work on further development topics, including the definition of AES67 profiles.

Open Control Architecture (OCA, AES70). The 3-part AES70 suite was published January 2016. A revision to the suite has been completed and will soon be issued for public Call-for-Comment. There has been substantial improvement to connection management and support for UDP and Websockets has been added (existing version is only TCP/IP).

Network Directory Architecture. This group is awaiting industry feedback on its statement of requirements document for a highly scalable directory service architecture, possibly including automatic network discovery, suitable for professional media networks.

AES70 Recommended Practice for AES67 Connection Management. This new project has the following scope: Publish an informative document that recommends the way to implement AES70-CM3 connection management for AES67 unicast and multicast connections.

Other work. AES5, on preferred sampling rates, has undergone some revision for clarification. A new project has been started to define use cases for RJ45 connectors to carry analog and AES3 signals on its 4 pairs. There is work to harmonize AES60 Core audio metadata with the latest EBUcore (v1.9).
