*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 phys- ical 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 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 picture, two part, using physical channel, ATSC air.
