What is the allowable path for upstream data? Is there some reasonable realtime communication path from the cable box to the provider or does it all have to be unidirectional?

Like maybe I can log into a website or phone someone to subscribe, but there's no two way communication with the decoder itself. So just like real-world cable, satellite, or broadcast.

When you pay over a tls channel, vend a one-time use key. Then use the key to decrypt the content as it’s streamed to you? The key can be global per event to save on the broadcaster’s end.

How do you get the key to my decoder, and only the subscribed decoders? Only one-way comms to the decoder :)

The unreliability is interesting ... like do we apply some kind of FEC on top of everything? Also, what kind of MACs are worth having? Should we let corrupt frames decrypt? Many video codecs can cope with corruption after all.

that insight - it’d be super valuable to build in a UX that displays what you’re subscribed to from the decoder’s POV and for that to involve an e2e check.Thanks. Twitter will use this to make your timeline better. UndoUndo

Looking at the responses so far, I guess no one is concerned about encrypting 6 Million+ streams with unique keys live, no latency?
-
Well, if it's say 100 bytes per envelope, including some metadata etc, that's 600MB ... so yeah it might take a while to send all of that.

What problem are we trying to solve? DRM? Subscription management? (I know you said PPV, but is that the only thing?) Is the view immediate, or can be delayed? Can I view it for 24 hrs or 1-shot?

I don't have a real problem, I'm just making this up as a fun exercise. I suppose this is a kind of DRM. Let's say it's live video, like sports, for one shot, and it'd be neat to be able to subscribe to an event as late as possible.
