Re:“What’s the waiter doing with the computer screen?” by crististm on Saturday February 25, 2012 @03:31PM (#3633778)
I call a "channel" the frequency of a station; "program number" is what the TV gives me on the remote control to go to a station - the number on the screen.

In that framework, the TV has two frequencies (or channels) associated to the same "program number". I can switch between the two by entering from the remote the same "program number" twice or more times...
