I remember using MythTV in the beforetimes, and you’d record the show off the cable tuner, then it would process the file and remove the commercials based on volume levels and light signatures. It was remarkably good at it and was how I watched all TV until streaming came around.
I would imagine someone could do the same even better today with an AI model that would recognize all the ads and deliver an edited stream. The problem is that the video would have to be downloaded beforehand and then the streams stored elsewhere and referenced by an addon that redirects you.
