4.8.2.5. Allow Key Transitions During
When the EMC is put into the emergency mode the EMC can have the option of allowing key
transitions whilst in the mode or not. If key transitions are required then tick this box.
4.8.2.6. Force Keyers When On
When the EMC is put into the emergency mode the keyer settings can be forced to a known state
using the "On-Air on Emergency" option for each keyer. If this is required then tick this box.
4.8.2.7. Restore Keyer Settings After
When the EMC is put into the emergency mode the EMC makes a note of which keyers are on-air
before the mode and will optionally restore these settings when the EMC comes out of the emergency
mode. If this restoration is required then tick this box.
4.8.2.8. Auto Toggle
This setting forces the M2100 control of the EMC to be toggled with the Emergency enable/disable.
4.8.2.9. Hold on Transition
When checked, Emergency will stay on-air regardless of transitions. If disabled, Emergency will go off-
air with the next transition.
4.8.2.10. Force VOs off
This option allows for the VOs to be turned OFF when the Emergency Mode is turned ON.
4.8.3. Key Signal Settings
4.8.3.1. Gain
This control is the equivalent to the softness level in an analogue keyer. The edit box sets the amount
of gain applied to the key signal of this keyer. It is nominally set to a value of 75 (34%) for a key signal
in the range 16-235. This setting should be set according to the key signal range.
75 for range 16-235
65 for range 1-254
It should always be in the range of 16 - 235.
4.8.3.2. Clip (Offset)
This control is the equivalent to the clip level in an analogue keyer. The edit box sets the mid point of
the key signal for this keyer. This value is the default value set for the EMC and is used after a power
cycle or re-configuration; the user can optionally change this value via the control panel. This control is
expressed as an 8 bit digital video value (between 16 and 235). It is nominally set to a value of 125
(50%) for a non-inverted key signal in the range 16-235. This setting should be set according to the
key signal range and inverting state.
