Digital channels have a Physical, Major, and Minor channel
number. The Physical number is the actual digital channel
number, the Major is the number that the channel should
be mapped to, and the Minor is the sub-channel. Since
the ATSC tuner automatically maps the channel to the
Major number, the Physical number is not required when
sending a command.
