Camport Operation (Stand-Alone)
When Camport Auto Sense is enabled as above, the STB’s
source will switch to the AV IN 2 Video Aux source when-
ever a plug is inserted into the AV IN 2 Video input.
When the plug is removed, the STB will switch back to the
previous channel or input source that was being displayed
before the plug was inserted. However, if any direct access
to an RF channel or Aux channel is requested while the
Camport is active, then, when the video plug is removed,
the STB will switch to the last requested channel. Source
changes using any Source keys (INPUT) are ignored.
Channel Up/Down and Flashback commands are not direct
access tuning commands, and they are also ignored.

Camport Operation (FTG or PPV)
The operation will be similar to that of the Stand-alone
Mode. However, when the Channel Map is maintained
external to the PTC (i.e., FTG and PPV), Channel Up/
Down or Flashback keys are sent as Direct Access tuning
commands to the PTC/STB.
