Video and Key Inputs and Outputs
Outputs
Regardless of the format of the input signals, the Signal Processor
can provide outputs in any composite format.
Signal outputs are provided by output modules installed in the
Signal Processor Frame (see
Figure 1-5 ). Each output module
provides four video/key signal outputs of a given type, with up
to three buffered outputs per signal channel.
Since each output module cell is dedicated to specific functions,
the format of each output signal is determined by the type of
output module installed in that cell. The following choices of
output modules are available:
■ Composite Analog (4 signal channels; 3 outputs of each
signal)
■ Parallel Digital (4 signals; 1 output of each signal)
■ Serial Digital (4 signals; 3 outputs of each signal)
Standard (Analog) outputs include:
■ (DSK) Program Video
■ (DSK) Program Key
■ Mask Bus
■ Switched Preview Video
Optional outputs (Analog and/or Digital) include:
■ M/E 1 Program Video, M/E 1 Program Key
■ M/E 1 Preview Video
