All data
are
transmitted by Hexadecimal code
*Two/One
part
Channel: 6th bit
This bit is used in
a
cable-ready
system.
*Using physical
channel: 5th bit
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).
