* 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).
Example)
1. Analog channel: NTSC cable, channel number(35), main
picture Command: ma 00 23 xx xx xx xx 01attribute(0x01):
main picture, two part(it's not mandatory), using physical chan-
nel, NTSC cable 'xx' data: don't care major and minor channel
number in case analog channel tuning.
2. Digital channel: ATSC air, channel number(don't know phys-
ical channel, major(30), minor(3)), main picture Command: ma
00 xx 00 1E 00 03 22 attribute(0x22): main picture, two part,
not using physical channel, ATSC air 'xx' data: don't care ana-
log channel number in case digital channel tuning.
3. Digital channel: ATSC air, channel
number(physical(20),major(30), minor(5)), main picture
Command: ma 00 14 00 1E 00 05 02 attribute(0x02): main pic-
ture, two part, using physical channel, ATSC air.
