AVA-C/O automatic change over
Whenever the main video signal has a fault,
the Change Over automatically switches to the audio/video emergency signals.
As soon as the preferential signal returns, it
resumes the starting conditions.
The switching can be controlled manually as well
as automatically, through a local or remote control.
The possible applications of this equipment are
many e.g.:
to switch automatically from the main signal to an alternative one (stand by) whenever the first one should have a fault during the transmission.
Broadcast of an excusing message: “The transmission is going to restart as soon as possible."
It can be used to switch from the
identification signal of a dumping point to the signal of the journalistic work
to be dumped.
Connecting audio and video output of a VTR to the
main input of the C/O this will switch to the above mentioned signals.
Finally, turning off the main signal, the C/O
will go back to the identification signals.
The Audio/Video Automatic Changeover is a stand alone that can be accommodated
in the ELMAN’s 1 RU multifuction-system subrack which can be inserted up to three standalone modules simultaneously.
The Audio/Video Automatic Changeover can be independently utilized also
being the apparatus provided with its own power supply and with all the
necessary connectors on a rear panel.
