Record everthing? Next to nothing?
Let me see, an ATSC transport stream is 8.7 gb per hout. So, if you have 10
transport streams, recording everything uses up 87 gb of disk space in an
hour.
Why, that's only 2 terabytes a day for the ota DTV channels I can receive
over the air. Then, add in a few hundred cable and satellite channels, and
I'm sure it won't be any more than 30 terabytes a day. And, if you are away
from home for a day and couldn't watch all that content, you'd only need to
double your storage. When one thinks of such large data bases, one
generally tends to think of redundancy and RAID arrays.
I just shopped for a new 400 gb hard drive, bob. It only costs $139. So,
to record a whole week OF EVERTHING would only cost me $24,325. I just
can't wait until hard drives are 1/10th current price, and that will only
cost $2,432.
In other words, your concept MAKES NO SENSE, bob.
Of course, if you were to remove duplicated programming, eliminate
commercials, and prioritize based on what you've watched before and your
expressed interests, that might fit into a Tivo-like box. But, that
wouldn't be recording everything.
Here's also something to keep in mind: the target. People only live 8,760
or so hours per year, and about 1/3 of that is taken up by sleeping, and
perhaps 1/4 by working. That means 7/12th of the time, people can't watch
TV.
I suspect that people can't watch 'much more' than 2 tv programs
simultaneously. That means there is about 5,110 hours per year that the
average person COULD watch TV, without counting driving time, family time,
etc. So, your system would store in a day about the number of hours of
television programming that a person could watch in a year.
This is absurd, Bob. But, the economics will only improve, as disk drives
get cheaper. That said, ti will be absurd for many, many years. Might work
in an area where there is only one channel.

P.S. That's the trick! Store everything to HD-DVR or Blue-Ray! It would
only take about a dozen or more drives continually recording, and those
disks are so cheap!
