AVB Ethernet Features
AVB uses the concept of streams and channels. A stream is a connection from one
talker to one or more listeners. One stream can be made up of 1- 60 audio
channels. The Ravenna option supports the following AVB features:
1)
AVB 1722 AVTP with multiple subtypes:
a)
IEC 61883-6 MBLA
b)
AM824, 24-bit Audio Encapsulation
c)
Support up to 2 streams
d)
Up to 8 channels per stream
e)
512+512 Channels of audio
f)
48kHz and 96kHz sampling rates
2)
IEEE 802.1Q/SRP
3)
IEEE 1722.1/AVDECC control
4)
IEEE 802.1AS/gPTP
5)
Compatible with Apple OS X devices, such as MacBooks and MacMini computers
6)
Media clock per the AVnu specification
BACH™ Controller Interface
The BACH board includes a Graphical User Interface to review and manage
the Bach board. It provides an interface to:
3)
Manage connections with ease
a)
Display discovered devices and streams
b)
Connect streams from network to local destinations
c)
Start, stop and monitor stream health/status
4)
Enable local BACH™ device configuration & status reporting. Examples include:
a)
Receive buffer statistics
b)
Ethernet statistics
c)
Alarms
The context is device-specific, meaning that:
1)
A stream “source” refers to this device’s source
