Audio Video Bridging (AVB) is a common name for the set of technical standards that provide improved synchronization, low-latency, and reliability for switched Ethernet networks. AVB embodies the following technologies and standards:
AVB was initially developed by the Institute of Electrical and Electronics Engineers (IEEE) Audio Video Bridging task group of the IEEE 802.1 standards committee. In November 2012, the Audio Video Bridging task group was renamed to Time-Sensitive Networking task group to reflect the expanded scope of its work, which is to "provide the specifications that will allow time-synchronized low latency streaming services through IEEE 802 networks". Further standardization efforts are ongoing in the IEEE 802.1 TSN task group.
To help ensure interoperability between devices that implement the AVB and TSN standards, the AVnu Alliance develops device certification for the automotive, consumer, and professional audio and video markets.
