For example: x The binary code to tune the sub source to an NTSC x cable channel is "1000 0001", which translates to "81" x in Hex. x * 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. 3 2 1 0 Step 0 0 0 0 0 0 0 1 0 0 1 0 NTSC Air NTSC Cable ATSC Air 0 0 1 1 ATSC Cable_std 0 1 0 0 ATSC Cable_hrc 0 1 0 1 ATSC Cable_irc 0 1 1 0 ATSC cable_auto 0 1 1 1 Reserved x x x x 1 1 1 1 Reserved 20.
