source, giving consistent and repeatable delay. If the video output frame rate differs from the
genlock source frame rate, the output will 'clock lock' to the genlock source. Clock lock
ensures that the output audio 48kHz clock remains locked to the genlock source.
When attempting to pass non-PCM audio (other than Dolby-E), ensure that Genlock is
enabled. If using an external reference, it must be clock-locked to the input video.

Timecode
The Timecode menu enables you to set up and control the unit's timecode options for VITC
(Vertical Interval Timecode), LTC (Linear Timecode), and ATC (Ancillary Timecode). In the HD
domain, both Embedded VITC and Embedded LTC are supported. In the SD domain, VITC,
ATC LTC, and ATC VITC are supported.
When present, timecode can be handed over from the input or internally generated. Where
the input frame rate is 29.97 fps, both drop frame and non-drop frame modes are supported.
For 29.97fps outputs, timecode can be configured as either drop frame or non-drop frame.

Operation
Genlock source
•
Reference
(default): locks to the incoming reference.
•
Input
: Locks output to input. When input and output frame
rates are integer related, selecting
Input
will force the unit to a
fixed processing delay.
•
Free run
: locks the output video to an internal reference
clock.
Reference status
Shows the status of the currently assigned reference. For example, if
genlock is assigned to input, status shows
Input
followed by the
current status of the input. If there is no signal on the assigned
reference, status shows
REF Loss
.
Mode status
Reports - Selected lock mode: Output format: lock status (
genlock
,
clocklock
,
freerun
)
V timing
Adjusts the vertical timing of the output signal with respect to the
reference signal, from line -563 to line 562 in steps of 1 line.
Default = 0 lines
H timing
Adjusts the horizontal timing of the output signal with respect to the
reference signal, from pixel -2640 to pixel 2640 in steps of 1 pixel.
Default = 0 pixels
Note:
Genlock timing adjustments will take effect only when the Genlock source is set to
Reference
