Before Beginning Image Creation
Before considering the operations of image creation proper, this section
describes how the various video sources are combined to produce the final
program output.
Video Signal Flow
In the DVS-7250 system, the output video of upper-stream image creation
blocks (banks) is fed to the final block where the signals are subjected to final
processing as required before being output as the final program video.
Final program output
The final program output refers to the video output from the PGM
OUTPUTS connectors of the switcher. It is the same as the video output of
the PGM/PST bank.
Examples of signal flow
The following diagram shows an example signal flow.
For convenience it is assumed here that the signals are fed in the fixed order
from M/E-1 to M/E-2, but in fact these banks can feed each other.
