Good morning,
I was doing some thinking over the weekend (while cooking ribs on
the grill :) ).
Does anyone know who much data 1 hr. of HDTV produces? Let's try
720 for
now and perhaps 1080. I'm looking for the file size if you store
the whole thing
in a single file.
Well, I didn't have any idea ten seconds ago, but now I know that one
hour should be roughly 3 GB. (So a movie should be 5-6 GB.)
ATSC allows rates up to 20 Mb/s, so 1 hour would roughly by 9 GB
(base 10).
Raw data from a mini-DV camera uses 25 Mb/s, but it is not compressed.
