But let's get back to reality here. The 704 X 480 SD stream, in a
typical ATSC multicast, would be bit starved, as most SD subchannels
are.
That is strictly a choice of the broadcaster. If this were the
primary service it is not likely it would be bit starved, and might
even look better than a bit starved 1080i encoding.
So you wouldn't expect to see the ultimate quality anyway. I'm still
wondering whether 704 X 480 at 60p can be sent at the same low
bitrates that are now being used for 480 at 60i. And you would need
to use 60i or 60p for sports, anyway.
480P will deliver BETTER image quality than 480i at the same bit
rates. t would CLEARLY be better for sports than 480i.
