Bonus March Chapter Meeting: SAS and Recent Digital Audio Protocols

While AES-67 Audio over IP and now AES-70 (GPIO and Control over IP) are popular in the radio broadcast world, a little known standard called IEEE-802.1 (also called AVB), is continuing to grow in the TV/Film, Production, Automotive and Consumer Industries. AVB (“Audio Video Bridging”) is an Audio over Ethernet (AoE) mechanism with auto QoS. With its growing popularity many other industries, the IEEE is positioning this technology to replace HDMI in entertainment systems, gaming consoles and TV Displays. AVB provides a mechanism for intuitive control and discovery. AES-67 is an Audio over IP (AoIP) topology, and while development is ongoing for “control and discovery”, (as is AES70), it’s poised to become the industry standard for radio broadcasting. We’ll outline key differences and typical applications for each protocol.

Al Salci of Sierra Automated Systems and Engineering Corp. visits us Wednesday, March 27 at 12 noon at iHeartMedia, 9660 Granite Ridge Drive, San Diego. He provides lunch, then will give the presentation. Members and guests are all welcome.
