|In January 2010, the AVnu Alliance announced the IEEE's (Institute of Electrical and Electronics Engineers) ratification and publication of IEEE 802.1Qav, the first of the core Audio/Video Bridging (AVB) standards. IEEE 802.1Qav defines forwarding and queuing for time sensitive streams and is part of a suite of standards developed by the IEEE 802.1 AVB task group. AVnu Alliance, a group of industry leading companies dedicated to promoting the emerging AVB networking standards across a broad range of markets including automotive, consumer electronics, and professional A/V, commend the IEEE 802.1 AVB Task Group for their hard work.
“We are pleased by the progress of the IEEE in completing the first of the foundational AVB standards” states Rick Kreifeldt, AVnu Alliance chairman and president. “With IEEE 802.1Qav published and two additional standards nearing completion, AVnu has the confidence to move quickly in developing our AVB compliance and interoperability programs which are vital for widespread commercial adoption.”
"The approval of IEEE 802.1Qav as a full standard is a major milestone in the development of interoperable time-sensitive networks, as it is the first time the core technology of Ethernet switches and network bridges has specific methods defined for traffic shaping. This allows an IEEE 802 network to provide assured (and low) delays for streaming data with minimal dropped packets,” states Michael Johas Teener, Chair of the IEEE AVB Task Group. “When combined with the almost-finished 802.1Qat Stream Reservation Protocol,” continues Teener, “IEEE 802.1Qav will be the fundamental toolkit to provide the kind of virtual plumbing needed for professional-quality audio/video networking."
Tony Jeffree, IEEE 802.1 Chair, further comments "The approval of IEEE Std 802.1Qav marks a significant milestone as it is the first of four 802.1 standards under development in IEEE 802 that support audio and video applications over local area networking technologies."
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) standards over various networking link-layers. Members of the AVnu include companies ranging from pro audio manufacturers like Harman, Shure, or Meyer Sound, to big brands like Samsung, Cisco, and Intel. The non-propriety AVB standard supports compatibility through the use of widely available products like very affordable network switches and wiring. Therefore AVB might have a similiar impact for audio/video distribution as MIDI used to have for keyboard instruments and recording technologies in the 80s.
