Actually, just callsign.  The number only comes into play for Live TV 
(it allows you to change to a specific channel) and the EPG.  If the 
number /and/ callsign match, the EPG will show the channel only once.

Or give them different callsigns if you want to be able to control which 
channel is used for scheduling.  The callsign is a user-editable value 
whose sole purpose is to identify channels to be considered by "this 
channel" rules--its value is irrelevant.
