The AES Convention at the Jacob Javits Center in New York heralds a welcome return to in-person events for the Audio Engineering Society. As a leading event for all things audio technology-related, the two-day show, collocated with the NAB NY Show, offers a dense program of workshops, panels, demonstrations, training, papers and more presented by some of the leading lights of the industry. It is followed almost immediately – albeit on the other side of the country in Hollywood, CA – by the annual SMPTE Media Technology Summit, a four-day conference event dedicated to exploring the most exciting advancements in media and entertainment technology.
The OCA Alliance – represented by Bosch Communication Systems’ Senior Scientist, Jeff Berryman – will be presenting at both events. At AESNY 2022, Berryman will be delivering a presentation on AES70 Control for IP Media Devices which will summarize the AES70 control architecture for media devices and describe new features in the standard’s upcoming release.
It will also introduce available AES70 developer tools and information resources for implementers, most of which are free. The session will take place in the AIMS Media-over-IP Pavilion theatre on the main AES show floor and is scheduled for Wednesday October 19th at 3:30pm and Thursday October 20th at 12:30pm.
The presentation at the SMPTE Media Technology Summit in Hollywood, CA, is a more general discussion of audio networking and control applications in today’s production environment. The presentation will cover media network standards as they apply to production environments, with particular focus on the relevant AES standards: AES67 for audio streaming, and AES70 for device control and connection management.
As part of a joint presentation with Brian Vessa from Sony Pictures Entertainment and Leigh Whitcombe, Berryman will present an overview of the role of media networking protocols in a production context followed by a more targeted presentation of AES70 as an industrial-strength device control solution. The full session will take place on Thursday October 27th at 10:00am.
"AES70 is a full-featured control and monitoring architecture for both real and virtual (i.e. cloud-based) media devices. Currently focused on audio device control and monitoring, AES70 is not itself an audio transport scheme but is designed to cooperate with and complement modern audio transport schemes such as AES67, SMPTE ST 2110-30, Dante, and MILAN," explains Berryman. "AES70 is in fact a fully engineered design intended for professional media systems. It is lightweight to implement, yet suitable for critical applications of all scales from tiny to huge. AES70 and its toolset are a ready-to-use solution for industrial-strength control and monitoring of network-based media processing hardware and software. However, as media control is a less well documented subject than audio transport, it’s vitally important to take advantage of the opportunities offered by conventions such as the AES and the SMPTE Media Technology Summit to educate a wider public."
AES70 is an open control and monitoring standard for professional audio and AV media network devices. From a single device and controller, to networks with almost any number of devices and multiple controllers, AES70 provides for powerful, high speed, low cost, robust system control and monitoring of devices from different manufacturers. The architecture operates on commodity Ethernet networking hardware, or via standard 802.11 Wi-Fi.
Control functionality allows system professionals to change and monitor all operating parameters of a network device, including the creation and deletion of signal paths, parameter adjustments for signal processing objects, network device firmware updates and management of access control. Control can also be limited to provide simpler ‘operator’ functionality; for instance, providing just level, mute, power on/off and fault indication. AES70 is available free of charge to manufacturers, system integrators and designers, to implement with their own and third-party network devices, as they require.
