Regardless of the Automatic/Manual mode, the operator always has the ability to instruct
the unit to switch to the other transport stream.
An IP Input receives a transport stream over UDP/IP or RTP/UDP/IP, on a given IP
Address/UDP Port combination, with an optional Source IP address specification. For each IP
Input, the unit allows an optional backup IP Address/UDP Port/Optional Source IP Address
combination to be specified. If the transport stream disappears from the primary address/port
combination, the port can switch to the backup address/port combination (if configured for
automatic redundancy). The automatic switch timeout can be set to a value between 2 and 45
seconds.
This level of redundancy is available for all IP input ports, and is independent of any connections
that may exist to the port. It uses no internal resources in the unit (i.e., it does not “count” as an
input or as a connection), but it has the following limitations:
•
It is only available for IP input ports.
•
The primary and backup transport streams must be available on the same Ethernet port.
•
The unit does not monitor the inactive stream. Therefore, if the active stream disappears
and the other stream not running either, the unit will be switching back and forth until
one of the two streams comes back.
