TIME 12:00 |
After one more second has elapsed (12 seconds in total) the human
operator has released the VIDEO panic button. AirCleaner will mark that frame
of video as the end of the violation (as shown by the upward arrow). Notice the
video output is already displaying masked video, a full 33 seconds before the
actual start of the violation content. All of the content between the actual
violation material and the output of the delay pipeline will be unnecessarily
masked by AirCleaner.

User Configurations
AirCleaner can be configured for a variety of purposes and applications, but the
following four user configurations are deemed to be useful for most broadcasters.
Each of the four user mode descriptions are followed with the significant menu
parameters required to obtain that particular configuration of AirCleaner. Refer to
“AirCleaner Menu Navigation” on page 68
for more information.
These user modes are intended to be used only as a guideline. In most cases, the video
and audio pathways will have the same delay; however, because of AirCleaner’s
unique architecture, there is provision for independent control of the audio and video
delays to compensate for audio/video synchronization errors of the incoming audio/
video feed. For sake of simplicity, this synchronizing parameter has been left out of
the user diagrams. Refer to
refer to “PGM Audio Offset” on page 73
for more
information.
Once the AirCleaner is programmed to suit a particular need, please remember to
save the configuration of the parameters, as detailed in the paragraph titled:
“SAVE
CHANGES made in the Options Menu” on page 70
