Looking back 10 years, I was saying the same things, only then I felt it was 25Mbit circa mike belshe's paper. So real bandwidth requirements only doubling every decade might be a new equation to think about... Required resolution of pictures is bounded by resolution of our eyes, which is fixed.
For TVs at homes, IMHO, baseband 2k should be enough, quality of which may be better than highly compressed 4k.
Masataka Ohta Yep. And despite our best efforts, nobody can hear the difference between 48khz/24 bit audio and 96khz/24 bit audio. The difference between 16 bit and 24 bit audio can be heard... but not so much on bluetooth earbuds! Attempts to make 10 channel audio more popular (like Atmos) appeal to a very narrow market.
Belshe's paper on "more bandwidth doesn't matter (much) from 2008: https://docs.google.com/a/chromium.org/viewer?a=v&pid=sites&srcid=Y2hyb21pdW0ub3JnfGRldnxneDoxMzcyOWI1N2I4YzI3NzE2
One thing to be said is that you could use more real estate instead of upping the resolution. like, having a jumbotron in your living room. will that be the next big thing? probably not, but it is a possibility Mike
