How do I make it so IR signals only go if channel changes

I'm sure this has been discussed but I'm not really sure what the feature is called so can't really search on it--anyways say if i'm watching channel 3--how do I configure the usb-uirt to NOT send a signal at the end of the hour if I'm staying on the same channel?
Our cable has a pop up channel block that pops up whenever you change the channel and hangs around for a bit afterwards--If we are watching the same channel and there is no need to send the signal, then it gets annoying.. Hope that makes sense.
thx
