Video Loopback Connections

The CD 900 can be used with a system switcher in video
loopback (VLB) mode. Details of this operation are included in
Extron's System 8/10 Plus switcher manual, part #68-078-01.
The composite video, and/or the S-video outputs from the
system switcher become the inputs for the CD 900. The RGB or
component output from the CD 900 then connects to a special
input on the system switcher. Figure 7 shows a typical video
loopback hookup.

The CD 900 decodes all composite video or S-video signals that
enter the system switcher, saving the cost of separate decoders
for each source.
