4.4 IP Redundancy
4.4.1 Introduction
Redundancy provides an alternative transmission route for video streams in case of a (partial)
network failure or when maintenance needs to be carried out on (a part of) the network
without interrupting operation.
The XCU supports IP Redundancy for the Media Network. The Media Network bay has two
ports (B1 and B2) that are used for redundant media transport over IP networks.
The XCU offers redundant video, audio and intercom outgoing streams from the unit to a
redundant media network (primary and secondary network).
Transmission redundancy is achieved by stream duplication. This means that the RTP (Real
Time Protocol) stream is duplicated and only the MAC addresses, IP addresses and UDP port
numbers are different for the redundant stream.
Note that the following streams are excluded from redundant operation:
•
All incoming streams from the network to the XCU (External video, Teleprompter video
and audio/intercom)
•
PTP locking
•
C2IP and AMWA-NMOS
