# Audio Video Bridging (AVB)
|
|
|
|
|
|
A set of IEEE standards that aim at providing time-synchronized
|
|
|
low-latency streaming services through IEEE 802 networks. The currently
|
|
|
in use AVB technology is called *Gen1* and consists of the following
|
|
|
IEEE standards (or standard amendments): 802.1AS, 802.1Qat, 802.1Qav and
|
|
|
802.1BA. However, ever increasing need and requirement for low-latency
|
|
|
time-synchronized communication resulted in on-going works on *Gen2* of
|
|
|
AVB. The requirements for *Gen2* are no longer shaped only by
|
|
|
audio-video industry but also by others (e.g. automotive).
|
|
|
It seems that AVB *Gen2* and White Rabbit have some commonalties and
|
|
|
these are investigated below. Firstly, the main features of AVB *Gen1*
|
|
|
are described briefly. Then the requirements, plans and features of AVB
|
|
|
*Gen2* are described.
