Audio Synchronization and Delay
Audio is synchronized to video by applying the same frame sync delay and converter delay
to the audio associated with that video path. By changing the
Input Frame Delay control,
you can adjust the frame sync delay and trigger the audio to re-synchronize with the video.
The audio synchronization will not occur immediately and will take roughly 10 seconds per
frame of delay in order to prevent any audio “glitch.”
You can add additional delay using the Audio Pair 1 Delay to Audio Pair 4 Delay
parameters. For information about setting additional audio delay, see Setting Audio Pair
Delay on page 26.
The user delay is always applied in addition to the audio synchronization and will cause an
audio glitch to occur when the user delay changes.
Configuring Input Reference Source and Input Frame Delay
To configure your input reference source and input frame delay, make the following
selections:
Setting Motion Threshold Mode
You can use Motion Threshold mode to set how the HUC6801
+
determines the difference
between motion in the input video image and signal noise. When Motion Threshold is set
to
Auto , the module sets the threshold value to an optimal level. When set to Manual , you
can use the Motion Threshold control to set the threshold value between 1 and 16, where
16 is used for images with high noise levels.
Setting Description Parameter Navigation
Select the genlock source.
(When the video input source is
HD-SDI, this parameter defaults to
Delay, because there is no external/
frame reference for the HD signal as it
bypasses the processor.) Video Setup Reference Genlock Source

625 options are displayed in the OSD. If
the standard is mismatched with the
genlock source, the Reference LED will
