GENLOCK
This function allows genlock to be enabled and the
reference source, reference standard and genlock
timing to be selected. The selected setup will be
indicated in the Home display.
Mode
Genlock
This allows the genlock function to be turned ON or
OFF. When set to the OFF position the unit will
ignore any reference signals and will be in the free-
run mode.
Ref Source
The reference source may be selected as:
Auto
The system checks both the
external reference inputs for a
suitable locking signal. When such
a signal is found the unit will
genlock to that signal. If a suitable
signal is not found the unit will
genlock to the input video signal
until a suitable external reference
signal is provided.
Ref A
The signal (if available) connected
to REF A input will be used as the
genlock source.
Ref B
The signal (if available) connected
to REF B input will be used as the
genlock source.
Input
The selected input signal will be
used as the genlock source.
Preset is to Auto.
Ref Standard
The reference standard may be selected as:
Auto
The unit will automatically detect
and use the standard of the Ref
Source.
1125/59.94
The unit is forced to accept only a
1125/59.94 (HD) reference input.
Note that this item is always the
current HD output standard.
525/59.94
The unit is forced to accept only a
525/59.94 analog reference input.
625/50
The unit is forced to accept only a
625/50 analog reference input.
625/24 or
625/23.98
The unit is forced to accept either a
625/24 or 625/23.98 reference
input.
Note: Important limitations
If the HD5050 output standard
uses a 74.25MHz clock then,
625/23.98
MAY NOT be used as
the external reference.
The output standards, which use
this clock frequency, are 1080i/60,
720P/60, 480P/60, 1080i/50,
1035i/60, and 1080SF/24.
If the HD5050 output standard
uses a 74.176MHz clock then,
625/24 MAY NOT be used as the
external reference.
The output standards, which use
this clock frequency, are
1080i/59.95, 720P/59.94,
480P/59.94, 1035i/59.94, and
1080SF/23.98.
