It depends on the exact method you’re using to control the TV. If it’s an IR blaster, if it’s harmony, if it’s a smart TV. The details maybe a little bit different, but the principles will be basically the same.
The following project topic shows how to do it with harmony as the IR blaster and IFTTT as a go-between, but basically you just set up a virtual switch for each of your favorite channels and then you can say "turn on ESPN quote “turn on the Disney Channel” or whatever.
But again it depends on the integration method between smartthings and the actual TV control device.
