Outputs
Video production switchers generate several different video outputs (Pro-
gram, Preview, etc.). A final program output from PGM is typically sent to
the transmitter for broadcast and/or to output devices for recording. Indi-
vidual M/E program and preview outputs and an additional switched
preview output are sent to monitors in the control room. These outputs
may also be routed elsewhere in the facility. Aux Bus outputs may also be
used for special purposes.
M/E, Program and Preview Output Buses
The Zodiak system has dedicated BNC output connectors for the following
signals:
• M/E 1 PGM and PVW,
• M/E 2 PGM and PVW,
• M/E 3 PGM and PVW (3-M/E systems only),
• Program A and B (with configurable clean feed),
• Preview A and B, and
• Switched Preview, selectable on the control panel from PVW PRI, ME 1,
ME 2, ME 3 (3-M/E system only), PGM A or PGM B.
Aux Buses
Video production switcher Aux Buses can be used to select and route
sources to specific destinations. For example, a source selected on an Aux
bus can be sent to an ISO recorder for instant replay. This can be done
directly by the Technical Director while she switches the program.
Remote Aux panels can be used to give different operators control over one
or more Aux buses. It is also possible to assign control of an Aux bus to an
external device, like a DPM, and allow that device to directly switch
sources as required.
