AUX IN – Video
(“Safe” Video Input)
When the AirCleaner is programmed to switch to the auxiliary input during a VIDEO
Panic Button press, this is the “Safe” digital video input into AirCleaner that is used
for the safe feed. If AirCleaner is programmed to defocus the video during a VIDEO
Panic Button press, then this input is not used.
This digital video input can be either Standard-Definition (SMPTE 259M / EBU-Tech
3267-E) or High-Definition (SMPTE 292M). The programmed video format of this
video input will always follow the configuration of the video output. This digital
video input can carry up to eight tracks (four stereo pair) of embedded digital audio.
TAP OUT – Video
(Screener 2 Monitor Video Output)
This digital video output is used only during “two screener” modes, in which there are
two separate users that are operating in series. This video output is downstream from
the video delay used by the first screener, and is used by the second screener to
monitor the video coming in to the second screener’s video delay pathway.
This digital video output can be either Standard-Definition (SMPTE 259M / EBU-
Tech 3267-E) or High-Definition (SMPTE 292M). The video format and line standard
for this output is configured in the Option Menu; this selection will be the same for all
the video inputs and outputs. This digital video output can carry eight tracks of
embedded digital audio.
REF IN
(Reference Input)
This input to AirCleaner accepts an external analog reference signal, either Bi-Level
or Tri-Level, that must match the frame rate of the incoming video signal. SD video
can only be locked to a Bi-Level external reference signal (or to the video input or
free run). HD video can be locked to either Tri-Level or Bi-Level reference, as long as
the frame rate of the video and the reference signal are matched.
The reference signal will lock both the
PGM OUT
and
TAP OUT
together in time with
the reference signal. The reference input is internally terminated (no loop-thru).
Reference can also be programmed to lock to the video signal present on the
PGM IN
or the
AUX IN
. There is also a reference “Free Run” selection. All reference selections
are made in the Option Menu.
NOTE
All video inputs and outputs can also accept embedded digital
audio and are user selectable. Refer to
Chapter 4 - Operations
for
more information.
