You see I don't care like they cared in the past how much they could decieve you with less data in terms of you not noticing the lower attention to color relative to luminosity or keeping only smooth data and missing a lot of spiky differences the sort of things a human is less likely to notice. This is the age of tflop level consumer AI so it's more now about two stages stage 1 using an AI driven flexible efficient codec for conveying efficient key data down YouTube like data rates. The second stage is about how well AI can convincingly represent the original data especially in terms of quality not as much accuracy with less keyed data with the given key data.
3 years after 1 tflop of AI can be found in cheapish phones a full AI driven video codec should be considered as a kind of t3 broadcasting standard so that we can have more data efficient hdr 480p(a lot of advertising and plus one channels and others tuned for raw channel numbers) 720p(the main slice of freeview)and 2k channels(premium channels) over the Ariel.
If the 480p channels were at 360kbs to 490kbs you could fit over 100 of them in a 40mb band where one old analogue channel used to sit.
If the 720p channels were 1.4 - 1.9 mb then you may get about 60 channels down 2 bands
At 3.2 to 5.8 mb 2k the last 2 bands could hold about 22 premium 2k channels.
So that's almost double the number of freeview channels with a lot more high clarity TV also.
