This was very informative. I had no idea that everything on the wire was encoded as MPEG-2 frames, including data/internet.
Yes, that’s the opposite of what I always assumed! Is this because the original plan was to have much dumber edge devices that are just selectors and decoders of MPEG-2 frames?
It reminds me of CD-ROMs, where as I remember it the original CD audio format was essentially usable in hardware (that is, with no “computer”-level hardware), then later had a data layer defined on top of it.
