o Listener: AVB endpoint receiving audio from the network. (Sink/ Destination)
o Talker/Listener: AVB endpoint that is both transmitting and receiving. All AVB endpoints used on Dana series
are by default Talker/Listener devices.
o Precision Time Protocol (PTP): Allows devices on the network to get a notion of global time in the effort to
synchronize with each other. PTP component in each AVB module can act as a Grand Master (providing
clock) or as a slave (receiving clock). Once a grand master negotiates and is selected as a sync source, all
units will synchronize to it.
o Streams: General term describing packetization of one or multiple audio/ video channels over the network.
Stream can be unicast or multicast. For the time being, the AVB module only supports unicast streaming.
Future revisions will provide additional features.
o Stream ID: Unique 64-bit stream identifier used by AVB transport protocols to identify streams.
1.3.2 Digital Signal Processing
E-power is fitted with a small fixed point Digital Signal Processor (DSP) providing basic filtering tasks such as gain
