Xbox one doesn’t have cec, so how does this work?

The Xbox one doesn’t have hdmi cec connectivity, this implies with out the join (which solely controls energy and quantity) the Xbox one can’t speak to your television. So, in that case, how does the Xbox speak to my television and inform it that it’s a sport? Thx prematurely 🙂 (additionally I checked and my tvs sport mode settings are set to let console resolve as a substitute of on or off, so that is the Xbox doing it.)
