This parameter has the following adjustable range:
•
= 0:01
Minimum value.
•
= 60:00
Maximum value (depending on memory installed, and
the video format AirCleaner is currently programmed
to use; maximum may be shorter than this).
The
Total PGM Delay
parameter determines the total audio/video delay (in
time) used inside AirCleaner; this is the delay between the audio/video on the
PGM IN
feed versus the
PGM OUT
. If the
Screeners
parameter is set to “
One
”, then the
entire delay is used for that single operator. If the
Screeners
parameter is set to
“
Two
” users, then the total program delay is divided between the two users, with the
Screener 2 Delay
parameter determining how much of the total delay
program delay is allocated to Screener 2.
The
Total PGM Delay
parameter has a variable range that depends on the video
format of AirCleaner (set in the Options Menu), as well as the amount of delay
memory fitted in the machine at time of purchase. The delay ranges from 1 Frame up
to 60 Seconds in the case of SD 525 or 625 video format; or it can range from 1 Frame
up to 6 Seconds in the case of HD 1080i video with AirCleaner Model-1 (which is
fitted with a smaller amount of delay memory, compared to Model-2).
This parameter has the following adjustable range:
•
= 0:00.0
Minimum value.
•
= 10:00.0
Maximum value +10 or –10 Seconds (depends upon
and is limited by the “Total PGM Delay” value).
The adjustment increments in tenths of a video frame in the menu display.
The
PGM Audio Offset
parameter is used to correct any possible audio-to-
video synchronization errors on the incoming audio/video feeding the
PGM IN
connectors on the rear panel of AirCleaner. If an upstream process causes the audio to
be “slipped” in time with respect to the video, this parameter can correct the audio/
video synchronization error.
The maximum possible
PGM Audio Offset
that can be programmed is +/–10
seconds. However, this range depends on the current
Total PGM Delay
value; if
the total program delay is set below 10 seconds, the range of the
PGM Audio
Offset
parameter will be decreased accordingly.
This parameter will increase or decrease the total amount of the
PGM IN
audio delay.
So, to advance the audio relative to video (which decreases the audio delay) a value
up to the value of the current
Total PGM Delay
may be entered, or to a
maximum of –10 seconds (whichever is smaller). In order to delay the audio relative
to video (which increases the audio delay) a value up to the value of the current
Total PGM Delay
parameter may be entered, or to a maximum of +10 seconds
(whichever is smaller).
