AES70 Gets an Update

The OCA Alliance calls it a “significant advancement”

The OCA Alliance said the AES has published the latest update to the AES70 suite of standards for control and monitoring of devices in professional media networks. 

AES70 is a system control approach intended to be paired with a digital network media transport mechanism like AES67, Dante and AVB/TSN.

The alliance described the latest release as “a thoughtful update that both enhances the standard’s usability and flexibility while expanding its capabilities to meet the dynamic needs of professional applications.”

In a press release, it wrote: “Making up the core standards, AES70-1, AES70-2 and AES70-3 form the foundation of the AES70 standard. AES70-2023 represents a significant advancement, bringing in a wave of new features and improvements. Fully backward compatible with all existing AES70 devices, a major focus has been on improving the understandability of the specification with revised, expanded documentation, more precise language and ten informative annexes to assist developers.”

It said the update also extends the connection management architecture with better support for redundant network connections and a clearer organization of functions. 

“There’s flexible support for connection negotiation and media transport sessions and this update sets the stage for the upcoming adaptations for media networks including AES67, ST 2110-30 and Milan.”

The alliance said AES70-2023 also defines various types of datasets such as media files, logs, parameter files and executables, allowing manufacturers to define custom dataset types as needed. 

“This extends to command sets and stored parameters. Devices can store predefined executables and operating parameter values for immediate or later use.”

This encompasses networks of all sizes including mission-critical applications, high-security applications, IP and non-IP networks, and local and wide-area applications. AES70 can control real or virtual devices located on premises or hosted by cloud services, consuming little computing power or network bandwidth.

The OCA Alliance is a not-for-profit that supports the AES70 standard for open control architecture.
