*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 thechannel band is NTSC air orNTSC cable, channel tuning
can be done by only physical channel. In this case, using phys-
ical channel bit must be low(0).
But ifthe channel band is ATSC air orATSC 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). Ifthe physical channel sending is
meaningless, you should set this bit high(1 ).
Example)
1.Analog channel: NTSC cable, channel number(35), main pic-
ture Command: ma 00 23 xx xx xx xx 01attribute(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 physi-
cal 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 analog channel number in case digital chan-
nel 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
