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(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 01
attribute(0x01): main picture, two part(it's not
mandatory), using physical channel, 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
physical channel, major(30), minor(3)), sub picture
Command: ma 00 xx 00 1E 00 03 A2
attribute(0xA2): sub picture, two part, not using
physical channel, ATSC air 'xx' data: don't care analog
channel number in case digital channel tuning.
3. Digital channel: ATSC air, channel number(physi-
cal(20),major(20), minor(3)), sub picture Command:
ma 00 14 00 14 00 03 82
attribute(0x82): sub picture, two part, using physical
channel, ATSC air.
