New York, NY (November 9, 2012)—The Audio Engineering Society and OCA Alliance have founded an AES standards project to consider OCA for a public standard for control and monitoring of professional media networks.

The goal of this project, identified as: AES-X210, “Open Control Architecture (OCA),” is to produce a public, open and royalty-free communications protocol standard for reliable and secure control and monitoring of interconnected audio devices in networks of 2 to 10,000 elements.

OCA will be a control and monitoring standard, not a media transport standard. It is intended to operate with a range of media transport standards such as AES-X192, “High-performance streaming audio-over-IP interoperability” - currently in development - and IEEE AVB. Together, these standards could offer a path to network application solutions for future media networks that include both media transport and system control functionality.

OCA is partially based on work done in the early 1990s by the AES24 project, a pioneering effort in network system control. Although AES24 never reached full standards status, it offered a number of advanced concepts, which have found their way into various developments over the years.

In the coming months, the AES-X210 task group, part of AES working group SC-02-12 on Audio Applications of Networks, will be meeting to render the current OCA 1.1 specification into standards form and to shepherd its processing through the AES's open standards process. Interested individuals are encouraged to participate. The full standards participation policy is available from the AES Standards website. During this period, the OCA Alliance will undertake various initiatives to support the work of AES-X210, and to define proposals for future extensions to the standard.

Crystallizing the focus of the new alliance, AES Standards Committee Chair, Bruce C. Olson remarked, “AES Standards has been deeply involved with standards for digital audio since starting work in 1977. The AES-X210 project to standardize OCA takes us to the next important milestone by integrating control with transport of audio over a variety of networks. Combined with a number of other projects in this exciting area of audio, the AES continues to lead the world in audio standards, which enable a thriving marketplace for compatible products from competing manufacturers. We are very pleased to collaborate with the leading manufacturers in the OCA Alliance on this standards project.”
