gain correction applied and then forwarded to output cable drivers and backplane I/O connectors
for distribution.

Video I/O Cards
Video input cards and output cards support the routing of SD, SWB, and analog video signals. Each
type of signal requires a unique type of card. For example, to support SWB signals, SWB input
cards and SWB output cards must be installed. Different types of input cards and output cards can
be inter-mixed in a single frame to meet specific switching configuration needs.
The output card does not need to match the signal type of the input card, but must be able to route
compatible signals. For example, if an analog video input card is installed it can be paired with an
analog video output card.
For each input card and output card installed, an associated backplane must also be installed. For
more information, see
There are two unique sets of input cards and output cards that support SWB signals: Classic SWB
card sets and Standard SWB cards. Both types of cards receive, switch and distribute SWB signals.
The two sets of cards differ in the switching configuration each supports. The Classic SWB card set
can be used individually for a 16 inputs x 16 outputs switching configuration, or coupled with
another Classic SWB card set to create a 32 inputs x 32 outputs switching matrix. For details, see
The following is a list of the different video input cards and output cards available:
Note
The analog audio output card is designed to function in a voltage-matched system
driving high impedance loads. The output drivers are not designed to drive 600
