Control TV with iPad and Apple TV?

[Howdee]

Is it possible to control a Sony TV, which is not a so called "smart TV" with the iPad along with Apple TV somehow?

Trying to figure out a way to do such a thing, but not sure how. I was thinking maybe perhaps I could mirror whatever was going on on my iPad via the Apple TV onto the TV itself? If that makes sense?

Or maybe there's something else that can be done?

Thanks in advance, much appreciated.
