6.4.2.1 Offline Mode
In offline mode, the entity does not enable the emissions and the input related
alarms.
6.4.2.2 Retire Mode
In retire mode, the entity coordinates its going offline with a stand-by entity taking
over the media transmission.
6.4.2.3 Preview Mode
In preview mode, the entity attempts to transmit a transport stream, but not the
associated emissions. This mode can be used for monitoring an output or for pre-
configuring a unit or transport stream output for fast redundancy switching.
6.4.2.4 Takeover Mode
Takeover mode is applied only for entities requiring external synchronization. The
device waits for the correct synchronization in this state, and transmits only when
the synchronization is correct.
6.4.2.5 Online Mode
In online mode, the entity transmits a transport stream output and other emissions
for online operations. The input related alarms are enabled.
Note: The redundancy switch coordination is supported by the Multicast Guard
Protocol (MGP). If MGP is disabled, retire, preview and takeover modes are
not available.
The following setmode transitions are not supported: offline to retire, retire
to preview, and preview to retire.
6.4.3 Configuring Setmode
To set up Multicast Guard Protocol (MGP), browse to Device Configuration >
Advanced Setup, select MGP Support and set the MGP Mode parameter in the
Properties widget. When using the front panel menu, select
Advanced/System/MGP Support/MGP Mode.
In off state, only offline or online mode can be set for both the unit and the media.
In module level state, only offline or online mode can be set for the unit, but any of
the five possible modes for the media.
In unit level state, any of the five possible modes can be set for the unit, but only
offline or online mode for the media.
