Our presentation will be AVB, AES-67 and AES-70 Presented by Al Salci, VP, Co-Owner of Sierra Automated Systems & Engineering Corp.

While AES-67 Audio over IP and now AES-70 (GPIO and Control over IP) are very poplular in the Radio Broadcast World, a fairly little known standard called IEEE-802.1 (also called AVB), is continuing to grow in the TV/Film, Production, Automotive and Consumer Industries.  AVB, which stands for “Audio Video Bridging”, is an Audio over Ethernet (AoE) mechanism with audio QoS, and, with its growing popularity in many other industries, the IEEE is currently positioning this technology to replace HDMI topology in Entertainment Systems, Gaming Consoles and TV Displays, etc.  AVB provides a well developed mechanism for intuitive control and discovery which is necessary for an HDMI alternative.  AES-67 is an Audio over IP (AoIP) topology, and while development is ongoing for “control and discovery”, (as is with AES-70), is poised to become the industry standard for Radio Broadcasting, (currently as a common platform for audio transfer).  We will look at a technology update on both of these paradigms outlining key differences between them, as well as, typical applications of how each technology is deployed.

Al Salci is a veteran analog and digital designer, and software engineer with over 30 years experience in broadcast communications. Originally from Toronto Ontario, Canada.  Al holds a Bachelor of Science from Mohawk College of Electrical Engineering &Technology.  Al started his career in Television broadcast designing vertical interval time code (VITC) editing systems for Evertz Systems and Leitch Video.  Al moved into radio in 1983 as Director of Engineering for McCurdy Radio Industries where he developed a wide range of products ranging from Audio Consoles, Large Scale Switchers, Intercoms, DAs and the original ATS-100 Audio Test Set.  Originally designed for ABC Networks, Al worked on the very first system utilizing large scaled switchers and RTOS automation for National programming syndication via Satellite to different time zones by sending control closures to trigger national or local breaks, ID’s liners, etc, many of which are still in use today known as NETCUE control.

Later, Al joined RTS systems in Burbank California as Senior Digital Design Engineer and developed Digital Intercom systems and 2-wire TV camera communications networks.

Al Salci joined up with Ed Fritz, another veteran design engineer in Burbank California and started Sierra Automated Systems & Eng. Corp. that specializes in high-density distribution, Radio Intercom systems, and Digital Audio Control console surfaces.  SAS is celebrating over 30 years of supplying high end, large scaled integrated digital audio distribution and console-networked systems.
