a possible unique key is constellation/position, frequency, polarity and
program_number (instead of vpid, as multiple services can share the same
video stream. Its useful when you switch out for local programmes and
join back for shared programmes. Its called dynamic PMT and common in

Some satellite packages sent out logical channel numbers but I have
configured my cable / terrestrial backend with manually selected
channel numbers and call signs. (so one station gets the same number,
no matter if its HD/SD or DVB-C/DVB-T)
If you do nothing you'll get numbers based on the transmitted program
number and video source id.
I don't think you'll get nice LCN for US FTA ;)
There are scripts for UK floating around that set nice channel numbers
(and other properties) based on service name or
original_network_id + service_id. Providing such a script for US FTA
might be an idea.
