FRONT PANEL OPERATION Revision 0.1 Page 5-25
5.1.2.44. Setting the V Phase
With the
V Phase Offset
control, you can set the vertical timing of the output video with respect to the
reference. Setting this control to
0
keeps the output video frame aligned with the converter’s reference
input or with the incoming video if reference is missing. For normal operation, the
V Phase Offset
control for each converter should be set to
0
. Increasing the value will delay the output video in one-
line increments of the output video standard. In order to advance the vertical timing of the output
video with respect to reference, set the control to the maximum total number of lines of the output
video minus the number of lines that you wish to advance the output video (e.g.: for 1080i/59.94 output
video the total number of lines is 1125, so to advance the output video 5 lines, set the value to
1120
).
When increasing the
V Phase Offset
causes it to go beyond the limit of the frame buffer, the
V Phase Offset
will wrap to the beginning of the frame buffer, resulting in a change of one frame of
throughput delay between the video input and the video output.

5.1.2.45. Setting the Timing Reference
Each individual converter is fed a copy of the reference that is supplied to the HD201x REF IN BNC.
To allow each converter to lock to this reference, the
REFERENCE SELECT
