With this control, you can set the vertical timing of the output video with
respect to the reference input set by the Reference Select menu item.
There are separate settings of V phase offset for each output video type.
Setting this control to 0 keeps the output video in time with the Genlock
reference or incoming video if genlock is missing.
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 the genlock video, 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 value 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 SD input and the video output. See Table 6 for the minimum
and maximum delays possible.
With this control, you can set the horizontal timing of the output video with
respect to the reference input set by the Reference Select menu item.
There are separate settings of V phase offset for each input video type.
Setting this control to 0 keeps the output video in time with the Genlock
reference.
Increasing the value will delay the output video in one-sample increments.
In order to advance the horizontal timing of the output video with respect to
the genlock video, set the control to the maximum number of samples per
line for the output video standard minus the number of samples that you
wish to advance the output video. (E.g. for 1080i/59.94 output video the
total number of samples per line is 2200, so to advance the output video 5
samples set the value to 2195.)
