minor number.

Digital channels have a Physical, Major, and
Minor channel number. The Physical number is
the actual digital channel number, the Major is
the number that the channel should be mapped
to, and the Minor is the sub-channel. Since the
ATSC tuner automatically maps the channel to
the Major number, the Physical number is not
required when sending a command.
Data 00: Physical Channel Number
NTSC air: 02~45, NTSC cable: 01, 0E~7D
ATSC air: 01~45, ATSC cable: 01~87
Data 01 & 02: Major Channel Number
Data 01: High byte Data 02: Low byte
Two bytes are available for the Major and
Minor, normally only the second byte is used.
Data 03 & 04: Minor Channel Number
Not needed for NTSC.
The table above lists the binary code which
must be converted to Hexadecimal before
sending. For example:
The binary code to tune the sub source to
an NTSC cable channel is 1000 0001, which
translates to 81 in Hex.
Data 05: Attribute
* 7th bit : For which source do you want to
change the channel.
* 6th bit: Use a two part or one part channel.
Most cases just use 0 since it's ignored when
using NTSC.
* 5th bit: Use 0 with NTSC since it can only use
the physical channel number. Normally use 1
for ATSC since most times it doesn't matter
what the physical number is.
* 4th bit: Set to 0.
* 3-0 bits: Choose signal type.
* Tune Command Examples:
1. Tune to the analog (NTSC) cable channel 35.
Data 00 = Physical of 35 = 23
Data 01 & 02 = No Major = 00 00
Data 03 & 04 = No Minor = 00 00
Data 05 = 0000 0001 in binary = 01
Total = ma 00 23 00 00 00 00 01
2. Tune to the digital (ATSC) local channel 30-3.
Data 00 = Don't know Physical = 00
Data 01 & 02 = Major is 30 = 00 1E
Data 03 & 04 = Minor is 3 = 00 03
Data 05 = 0010 0010 in binary = 22
Total = ma 00 00 00 1E 00 03 22
* Use the feature depending upon your model.
21. Channel Add/Del (Command: m b)
To add and delete the channels.
