IEEE P802.1Qav for Audio, Video Streaming Moves to Sponsor Ballot
August 3, 2009 // Published as a news service by IHS
The Institute of Electrical and Electronics Engineers (IEEE) moved a standard that will synchronize audio and video communications to sponsor ballot.
Experts said IEEE P802.1Qav - IEEE Standard for Local and Metropolitan Area Networks - Virtual Bridged Local Area Networks - Amendment: Forwarding and Queuing Enhancements for Time-Sensitive Streams will improve streaming audio and video applications over bridged local-area networks (LANs).
Improvements will come from performance guarantees that allow for time-sensitive traffic in a LAN and control delay, jitter and packet loss for wired, wireless and mixed wired/wireless L2 networks, according to IEEE.
When finished, IEEE experts said the standard will allow streaming audio, video and related content to be delivered with a very small and bounded delay.
"Current proprietary networks are hard to configure and very expensive," said Michael Johas Teener, task group chair for the Audio Video Bridging (AVB) Task Group within the IEEE 802.1 Working Group.
"Systems engineers want to use IEEE 802 standards-based networks such as Ethernet and Wi-Fi but they also want a guarantee of low delay," he said. "They need a more self-configuring system, which the IEEE 802 AVB standards will provide without the need for time-consuming resource management."
IEEE P802.1Qav is the first of the AVB standards going to sponsor ballot.
The next two are IEEE P802.1AS, which specifies how to do precise synchronization (allowing, for example, multiple networked loudspeakers playing the same audio signal to operate in phase, synchronized within one microsecond) and IEEE P802.1Qat, which specifies how to reserve resources in a network for delivery of video and audio streams.
IEEE P802.1Qav is sponsored by the IEEE 802 Standards Committee of the IEEE Computer Society.
