If
the
channel
band
is
NTSC
air
or
NTSC
cable,
channel
tuning
can
be
done
by
only
physical
channel.
In
this
case,
using
phys-
ical
channel
bit
must
be
low(0).
But
if
the
channel
band
is
ATSC
air
or
ATSC
cable,
there
are
two
cases
that
physical
channel
enable
or
disable.
If
the
physical
channel
sending
is
meaningful,
you
should set
this
bit
low(0).
If
the
physical
channel
sending
is
meaningless,
you
should set
this
bit
high(1).
