The ESPN Alternates, MLB Network Alternate, NBC Sports Network Alternate and the Big Ten Alternates now use subchannels and most of the part time HD channels like Fox Soccer Plus, FS Oklahoma, FS New Orleans, FS Detroit Plus have had them for a long time. In addition to just for basic reference, it would be a good indicator to see if any part time HD channels are going full time or if a future HD addition will be part time. Like when FS San Diego went 24/7 it first appeared in test mode without the subchannel.
I'm not sure what you use to grab the channel list, but if it's anything like the responses when you use the SHEF commands, the subchannel number is listed seperately. Channels without subchannels have FFFF (65535) while those that do have the number.
i.e. using /serial/processCommand?cmd=FA87 or the first 8 characters using FA83
ESPN2 209: 00D1FFFF -> 209-65535
ESPN Alt 209-1: 00D10001 -> 209-1
ESPN2 Alt 209-2: 00D10002 -> 209-2
MLB Network 213: 00D5FFFF -> 213-65535
MLB Network Alternate 213-1: 00D50001 -> 213-1
If you can spot a field or a block of characters with similar data (mostly FFFF, but the occasional 0001, 0002 and whenever the Big Ten Alternates go live 0003 and 0004) maybe you can modify the process to include it in a new column.
