Or maybe it would allow a slower less expensive encoder to keep up in real time. It takes a lot more work to squeeze the last nickel out of anything.
BTW, when folks here talk about 1080p are they really referring usually to 1080p @ 60 or 1080p @ 24? Because 1080 p @ 24 (movies) doesn't take any more bandwidth than 1080i @ 24 frames / sec and probably a bit less.
Yes, I think it means 60hz. I agree the requirements are odd.
60hz is what you need to get rid of flicker in the direct scanning
set, but most expensive sets don't direct scan, but convert
to high scan rates via a buffer internally. Since most interesting
sources are film at 24hz, its hard to see what is accomplished,
but then I don't see anyone doing the 1080p @ 24 format that
these real world facts would seem to make obvious.
