Overview
Figure 1-6 shows the video flow in a typical Model 3000 switching
system.
Video and key signals enter the Input Section of the Model 3000,
which consists of analog, parallel digital, and/or serial digital
modules. The analog signals are converted to digital format, and
all inputs are timed and conditioned.
The digital signals are then passed to the Video and Effects Section
where keying and mixing take place. This section also provides
effect modifications, such as wipes, that can be applied to selected
inputs.
In the Output Section, digital video and key signals are converted
to any desired composite format (analog, parallel digital, or serial
digital), as predetermined by the type of output modules
installed, before leaving the Signal Processor.
