7.5.8. Setting the Horizontal Phase of the Output Video – NTSC/PAL-M/525 Video
Video/SID
With this control, you can set the horizontal timing of the output video with
respect to the Genlock reference input when operating in NTSC/525 or PAL-
M/525 video mode. Increasing the value will delay the output video in one-
sample increments.
Warning: For a set output horizontal phase, there are a few
fine phase/H phase
combinations that will achieve the same position. For best results, set the fine
phase control to 0, set this control to get within 37ns of the desired position,
then adjust the fine phase control to get closer.
525 H phase
0 to 1715
0
7.5.9. Setting the Horizontal Phase of the Output Video – PAL-B/625 Video
Video/SID
With this control, you can set the horizontal timing of the output video with
respect to the Genlock reference input when operating in PAL/625 video mode.
Increasing the value will delay the output video in one-sample increments.
Warning: For a set output horizontal phase, there are a few
fine phase/H phase
combinations that will achieve the same position. For best results, set the fine
phase control to 0, set this control to get within 37ns of the desired position,
then adjust the fine phase control to get closer.
625 H phase
0 to 1727
0
7.5.10. Monitoring the Horizontal Delay between the Input and Output Video
Video/SID
This item displays the horizontal delay between the input and output video.
This value is useful to monitor while you are adjusting the H phase parameters
and debugging system issues. One count is equivalent to 8 clocks of 27Mhz
video.
H Delay
7.5.11. Setting the Vertical Phase of the Output Video – NTSC/525 or PAL-M/525 Video
Video/SID
With this control, you can set the vertical timing of the output video with respect
to the Genlock reference input when operating in 525 video modes. Increasing
the value will delay the output video in one-line increments.
525 V phase
0 to 524
0
7.5.12. Setting the Vertical Phase of the Output Video – PAL-B/625 Video
Video/SID
With this control, you can set the vertical timing of the output video with respect
to the Genlock reference input when operating in 625 video mode. Increasing
the value will delay the output video in one-line increments.
625 V phase
0 to 624
0
7.5.13. Monitoring the Vertical Delay between the Input and Output Video
Video/SID
This item displays the vertical delay between the input and output video. This
value is useful to monitor while you are adjusting the V phase parameters and
debugging system issues.
