Example: In a home with four displays connected, if users in every room want to watch satellite on different
channels, there must be four satellite receivers set up as sources. With custom programming, each output
can be programmed to use only one of the satellite source inputs, giving each output a dedicated cable box,
while allowing other less-used sources to connect to any output.
