AVnu Alliance

The AVnu Alliance is an industry forum dedicated to the advancement of professional-quality audio/video by promoting the adoption of the IEEE 802.1 Audio/Video Bridging (AVB), and the related IEEE 1722 and IEEE 1733 (which extends RTP for use on AVB) standards over various networking link-layers. The organization will create compliance test procedures and processes that ensure AVB interoperability of networked A/V devices, helping to provide the highest quality streaming A/V experience.
