AVB Glossary
AVB Endpoints
A device used at the edge of the network that has correct hardware to receive
or send signals into or out of an AVB network. These will then be configured
as talkers or listeners on the network. A common application will be to have
a talker transmitting a microphone audio signal to a listener elsewhere on the
AVB network.
AVB Timing Domain
The boundary between an AVB-capable bridge/switch and non-AVB-capable
bridge/switch.
Bridge
Ethernet appliance with the AVB standards implemented. Acts as a conduit
between talkers and listeners. Also referred to as a switch.
Switch
Commonly used to refer to an AVB bridge.
BMC Algorithm
The Best Master Clock Algorithm is used as part of the Grandmaster election
process.
Clock Synchronization
AVB devices each contain a time-of-day clock, and these clocks are
synchronized to the clock of the chosen grandmaster clock in the system. Each
AVB source device is master-capable. This master is either dynamically chosen,
or can be statically configured. This clock synchronization allows multiple
data streams to be synchronized, and provides a common time base for the
sampling (at a stream talker) and presenting (at the stream listener) of stream
data.
gPTP
Generalized Precision Time Protocol
Grandmaster
Refers to the network wall-clock time provided by the 802.1AS protocol.
Talker
An AVB endpoint capable of transmitting one or more streams to the network.
