With the composite/component connectivity, these could be used to tune channels if the RTV can be set to irblast channel changes similar to the way it changed channels for my SAT boxes.
Key would be finding IR codes that work...
and then maybe that would be problem, what can I tell my RTV is coming in on the composite/component inputs?
Step 1. Finding a Set Top Box that does not make use of a hash (-) mark to tune any or all sub-channels. If the box requires a hash mark to tune anything, you have one SLIM chance to get that box to work.
Step 2. Building an IR Blaster file (.rid) that controls this box, should one not exist.
Step 3. Creating a custom line-up in WiRNS.
Biggest obstacle is Step 1. A Replay will only send the following IR commands to your STB: Power, 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 0, Enter. It understands nothing else. The "Power" command is only used when you are setting up your RTV to command the box ("Press Ch+ to toggle STB Power")
There are some work a rounds, the first being to hope that your cable system makes use of logical channel numbers for Clear QAM, and doesn't stack channels on one virtual one, so that you could tune main (-1) channels if your STB default tunes to main channels.
The other way is to hope there is an unused digit in your lineup that you could substitute with a hash. You'd need to create a very custom RID file, replacing that digit with the hash, and creating a custom lineup substituting the hash with the digit. i.e. -- "8" is unused, so to tune 11-3, replace "-" with "8" and send 1183; create custom channel lineup to suit.
Oh, and you would be limited to four digits, including the hash, in any custom lineup you create.
Not easy or trivial, but possible.
There used to be a thread on the subject "What STB's can be controlled by RTVs" or something the like.
I have some CM-7000's for OTA, and CM-7001's for QAM. The former is better for OTA. The latter only does "-1" channels.
