AVB In

The AVB Input and Output are on the same physical card but are represented in the Q-SYS design by an AVB Input Component and an AVB Output Component.

The AVB Intput component provides connections for inputs up to 32 channels in 4 streams for devices supporting the AVB protocol. Other combinations of input/output are described in the Properties section below. Connection is made with CAT-5 / RJ-45 connector.

For hardware information, see CAN32 – AVB Audio Video Bridge Card.

Status

Control	Function	Default / Range
Status	Displays the current text and color status of the component: OK: The device is functioning normally. Initializing: The device is in the process of a firmware or configuration update, or the design is starting. Compromised: The device is functioning, but a non-fatal problem exists. Missing: The device cannot be discovered. Fault: The device is malfunctioning or is not properly configured. Unknown: This status appears during a Core reboot (for example, during a firmware update), or when a design is being pushed to the Core and before it has started running. Not Present: If applicable to the device, this status appears when the device is not connected to the network and its Is Required component property is set to 'No'. This status also appears if the device component's Dynamically Paired property is set to 'Yes', pairing has not been assigned in Core Manager, and the device component's Is Required property is set to 'Yes'. See Dynamic Pairing.	N / A

Listener Stream Connections

There are two ways you can connect an AVB Listener to an AVB Talker:

AVDECC (1722.1) (see https://avb.statusbar.com/article/1722.1-features/): This is the typical method and it involves a 3rd-party AVB management software for example: Riedel AVB Manager or Pivitec's AVDECC Controller. There are others available.
Directly via "Full Stream ID": Each stream on the network has a unique 64-bit stream ID (Full Stream ID). If you know the Full Stream ID you can just tell your Listener to listen to that stream and bypass AVDECC and any related 3rd party software.

Control	Function	Default / Range
Clear (Momentary button)	Removes all Listener/Talker mapping (AVDECC or Full Stream ID), disconnects the Listener from the Talker and audio stops.	N / A
AVDECC Entity and Unique ID	Read Only. IEEE-defined 64-bit Extended Unique Identifier of an AVDECC Entity. These codes are automatically derived from the Talker Stream connected to the Listener.	N / A
Full Stream ID	Read/Write. Enter the Unique 64-bit stream ID of the Talker Stream. When this information is entered, it removes the AVDECC information for that stream.	N / A
