Crystal Vision
Control and Status monitoring
Frames
Select a delay of between 0-10 video frames for the video path.
As the audio path is not affected by this delay, this control will
delay the video with respect to the audio. Audio channels will
be delayed by the same amount if ‘Match video frame delay’ is
selected by the
or
controls.
0-42ms
Select a delay from 0 to 42ms in 0.1ms steps that will delay the
video and audio with respect to the reference source if the
output timing reference source is Ref1 or Ref2 – otherwise, this
delay is an additional delay.
0-100us
Select additional delay from 0 to 100us in 1us steps. See ‘0-
42ms’ above.
0-1us
Select additional delay from 0 to 1us in 5ns steps. See ‘0-42ms’
above.
Line / Pixel
Displays current delay between video input and reference in
video lines and pixels.
Apply to all
formats
Selecting this will apply the currently displayed delay to all
possible input video formats.
Reference
source
Select the options for the synchroniser
reference video. The hierarchy runs from
left to right, so Ref1>Ref2>Video>Freerun
will attempt to use Ref1 initially and if that
fails to use Ref2 and so on. If the reference
and video frame rate become incompatible,
the card will attempt to use the other
reference source and if that is not
compatible, lock to the input video. With
the video input selected as reference, the
synchroniser is effectively disabled.
Active source The source being used as the synchroniser reference is
displayed here i.e. ‘Ref1, Ref2, Video or Freerun’.
Force relock
Applicable when ‘Auto Relock Enable’ control is de-selected.
Selecting this will force the synchroniser to relock after a
reference is restored.
When this control is operated, the card
internal logic will start at the top of the currently selected list
and move down it, picking the highest available timing
reference source. As video output is disturbed during the
relocking process, this control gives the user the opportunity to
relock at a non-critical time.
