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 physical channel bit must be low(O),
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(O), If the physical channel sending is
meaningless, you should set this bit high(1 ),
