HDTV is old now #22

Closed timj closed 6 years ago

In the conclusions we say:

About a thousand observations of each position across half of the Celestial Sphere will represent the greatest movie of all time: assuming HDTV resolution (2.1 Mpix/frame) with 30 frames per second, and 270 color images per position (e.g., the $ugr$ and $izy$ color-composites, c.f. Table~\ref{tab:baseline}), it would take about eleven uninterrupted months to view this color movie (equivalent to about 4,000 feature films).

but this is now showing its age because these days we watch movies in 4K UltraHD resolution (8.3 Mpix/frame). Also, to be pedantic, movies are usually 24 frames per second and not 30.

ie, the pixel count is 4 times too low but the frame rate is 1.25 times too high. I think this means our "feature films" number is 3.2 times too big.

Yes, this is dated text and a leftover from the fundraising days... I propose that we remove that text (I'd do it but don't want to collide with you - please let me know if that concern is now moot [also, we need to give a signal to Michael when it's ok for him to resume editing]).

I am not editing text at the moment. I'm working on author lists now. I have told @michaelstrauss he has permission to edit.
