Brent may have a fix that can be more automated.
Jack is correct.
If the uplug/plug works then you install one of our HDM-AIO2 on the output of the CATV STB, the AIO2 has a relay triggered (you need to provide a controlled relay for this*) Hot Plug interrupt function. When ever you are not watching the CATV STB you open your controlled Relay and for all practicable purposes the HDMI cable is disconnected.
