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.
* 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
