21. Channel Tuning (Command: m a)
G
To tune channel to following physical/major/minor number
Transmission
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
Data 5:
* 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 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
