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 from
the Major / Minor number, the Physical number is not required when
sending a command in Digital.
