* 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 tun-
ing can be done by only physical channel. In this case, using
physical 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).
