We had a conversation at work yesterday about this, specifically in the context of TV, and potentially having a camera/capture card + microphone + ML model to identify and mute ads automatically
I saw a college hackathon project and the team only needed audio cues, because there were distinct change points you could detect, sharp changes in audio level or very small gaps in audio iirc. The harder part was deciding when to unmute, are you between commercials or resuming content
