AVnu is A-OK for AVB

STANDARDS COME AND GO, but when something comes along that’s picking up widespread support in the consumer, automotive and pro audio markets, and sponsored by well-known names such as Broadcom, Cisco, Harman, Intel, Samsung, Xilinx, Analog Devices, Applied Micro, Audinate, Avid, Barco, Biamp, Meyer, Shure, Sennheiser, and others, you gotta take notice.

Founded just a year ago—and celebrating its first birthday at InfoComm—the AVnu Alliance is dedicated to advancing pro-quality audio video by promoting IEEE 802.1 Audio/Video Bridging (AVB) standards over various networking link-layers. AVnu promotes the benefits of AVB technologies and will create compliance test procedures and processes that insure AVB interoperability of networked A/V devices, with the goal of better A/V experiences for end users. For anyone involved in the installation/manufacturing/sales/distribution/operation of A/V products—meaning everybody in our industry—AVnu is a good thing.

And learning more about AVB is a good thing. This month’s InfoComm show is the ideal opportunity for contractors to learn more about the practical benefits of the emerging AVB standards. To that end, the alliance will host a technology and product pavilion in the main hall at Booth C7934 on the show floor with various Alliance companies demonstrating their use of AVB. The Alliance members also invite all InfoComm attendees to their first-birthday celebration at the pavilion on Thursday, June 10 at 4:00 pm.

Keeping with education theme, “Designing The World’s First Ethernet AVB Systems with HiQnet System Architect�—a training session hosted by Harman—will focus on configuring an Ethernet AVB system in a House of Worship system design. It happens Wednesday June 9 from 2:30 to 4:30 at Room N208.

Also not to be missed is a panel discussion on Friday, June 11 moderated by InfoComm’s Dan Goldstein, presenting a detailed explanation of AVB, the advantages of this open, non-proprietary technology and the importance of a compliance program in promoting the interoperability of AVB devices.
