offset for each output video type. Setting this control to zero keeps the output video line aligned with the
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 the user wish
to advance the output video. (I.e. for 1080i/59.94 input video the total number of samples per line is 2200,
so to advance the output video five samples set the value to 2195.)
Vertical Phase Offset:
With this control, the user can set the vertical timing of the output video with
respect to the reference input set by the
Reference Select
control. There are separate settings of
V phase
offset
for each output video type. Setting this control to zero keeps the output video frame aligned with the
reference.
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 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. (I.e. for 1080i/59.94 output video, the total number of lines is 1125, so to advance the output
video five 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.
NOTE:
The slider is available for selecting
H
and
V Phase Offsets
. To increment, click on the
right hand side of the slider. To decrement click on the left hand side of the slider. The slider
can also be selected and dragged across the available range if gross movement is desired.
5.1.2. Video Monitor
The Video Monitor section enables the user to view the status of video related parameters.
PGM IN A:
The
PGM IN A DIN Video Standard
reports if a valid video signal is presented to PGM IN A
and what standard has been detected when it is present.
The functionality for
PGM IN B
,
PGM IN C
and
PGM IN D
is the same.
Video Playload ID:
This field reports if a valid Video Playload ID ANC packet has been detected and will
display video format information.
5.1.3. 4K Inputs
4K Input Detected:
This field indicates whether or not a 4K input has been detected based on the input
detected on PGM IN A, B, C and D. If a 4K input has been detected, it displays the video format.
Additional video Delay:
These fields allow the user to set the additional video delay in addition to the
processing delay for PGM IN A-D. Up to 30 frames of addition video delay can be added to each of the 4
links.
Total Video Delay:
These fields indicate total video delay for PGM IN A-D in ms.
