selected lock source (RGB1 in this example). The lock mode can be either Off,
Genlock or Lock & Mix, with the operation of these shown in the following table:
Lock mode Description
Off The output resolution of the Output is defined by the setting
for Output Resolution and there will be no background
source visible.
Genlock The output video will be “Genlocked” to the selected lock
source. The output signal will be synchronous to the input
sync and adjustable but there will still be no lock source
visible.
Lock & Mix The output video will be locked to the selected source, the
syncs will be locked (but with an additional internal video
processing delay) and the background for the output will be
that of the Lock source (unless foreground and background
are swapped).
In both Genlock and Lock & Mix modes the source selected for the lock input
determines the resolution of the Output image. The output resolution for the entire
image can be no different than the resolution of the lock source. All
synchronization signals are re-generated within the unit so they may look slightly
different when compared on an oscilloscope to the original source.
Before turning the Lock feature on, you first must select a valid
Lock source. Not all Lock sources are available, depending on
the main Input source in use (see Adjust windows). For
instance, you cannot overlay one CV or YC source over a
different CV or YC source, or one RGB/YUV source over another RGB/YUV source
– you are restricted to overlaying CV/YC over RGB/YUV, or RGB/YUV over CV/YC
(the exception is where you can overlay one source over itself).
Your unit can handle a very wide array of inputs and convert them all to a single
output signal with defined characteristics. This output resolution will remain in
place until changed or it may be overridden by the lock mode and source.
The top line of the display will show the current output resolution selected. Some
units will have a limited number of output resolutions depending on their function
(e.g. Down Converters are more limited than Video Scalers).
