It can't necessarily detect if the cable box is on.  Does your cable box 
have descrete codes for turning on and off or just a toggle code.  If 
descrete, you could just send the power on command as part of your

one for the digital channels.  You may need to use different zipcodes 
(just use the next closest zip code to you) in order to create two cable
