Audio Video Bridging (AVB) supports the deployment of professional quality audio and/or video (AV) over standard Ethernet while coexisting with other "legacy" (or non-AV) Ethernet traffic. This supports "Network Convergence," or using one simple standard Ethernet network for all communication needs.

To support AV applications, it is necessary for AVB systems to provide time synchronization and QoS.

Time Synchronization is needed so that multiple streams may be synchronized with respect to each other. For example:
QoS is needed to ensure:
The time synchronization and QoS requirements for AVB systems are defined in the following set of IEEE Standards:
