*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).

20. PIP Input Select (Command2:y)

GTo select input source for sub picture in PIP/Twin pic- ture mode.

21. Channel Tuning (Command: m a)

GTo tune channel to following physical/major/minor number

Transmission

[m][a][ ][Set ID][ ][Data0][ ][Data1][ ][Data2][ ][Data3][ ] [Data4][ ][Data5][Cr]

Data 0: Physical channel number (Transmit by Hexadecimal code)

*NTSC air: 02 ~ 45

NTSC cable: 01, 0E ~ 7D

ATSC air: 01 ~ 45

ATSC cable: 01 ~ 87

Data 1, 2: Major channel number(two part)/channel number(One part)

*Data1: High byte

Data2: Low byte

Two part channel number: Major number-Minor number

One part channel number: If the channel band is ATSC digital cable, it can be used. In case of using one part channel number, minor channel does not need.

Data 3, 4: Minor Channel Number

*Data3: High byte

*Data4: Low byte

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(physical(20), major(30), minor(3)), sub picture

Command: ma 00 14 00 1E 00 03 82

attribute(0x82): sub picture, two part, using physical chan- nel, ATSC air
