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.
