better result may be achieved by disableing this feature,
note however then the output from the streamer will be very
poor as well.
Adding a new input stream
In the Input Control pane (on the extreme right of the main display window), add the
multicast/unicast IP address and port.
Click the
Add
button. The input module will now issue an IGMP join for the selected
multicast and start to analyze the incoming stream. The service found on the selected
multicast will be listed in the service view in the lower part of the input page.
Removing a multicast input
Select the input to be removed by activating the tick box on the left hand side of the
input entry (in the “Existing IP inputs” pane).
Click the
Selected
button under the Remove input part of the input control.
It is possible to apply filters on the information displayed in the GUI. Selecting the
Service View for a selected multicast, only the services associated with this multicast
will be displayed and clicking on one of the listed services will display more detailed
information about the different PIDs like PMT, PCR, video, audio, etc. Selecting the
ASI PID View will display only the PIDs associated with the selected input. It is also
possible to click on any of the PIDs to get more detailed information about that PID.

IP Input Redundancy
Overview
Input redundancy is designed to handle redundancy on the input streams. Input
redundancy will remedy failures from outside the system, such as with a cable break-
down, which result in link loss on the IP input module and the absence of a bitrate on
the dataport.
The chassis will have two IP input modules. One IP input module will be configured to
serve as the main module while the other will be configured to serve as backup. In
the event of input source failure, the IP input source will switch automatically.
It must be noted that input redundancy configuration is only supported for IP input
modules.
Hardware requirements
The system must be equipped with at least two IP input modules. If there are only
two IP input modules, the main module must have MMI functionality. One module is
designated the main module and must have MMI functionality, while the other is
designated the spare module.
If there more than two input modules in the chassis, any module can host the MMI
functionality without affecting redundancy.
The redundant module must have the same input configuration as the main input
module (configuration is mirrored). The selected redundant IP input card cannot be
configured manually, and is not available for separate use.
Alarms that cause switching
The system will automatically switch from main source to backup source based on the
presence of the following two alarms:
