Novel idea for a DVR
|
|
|
| If Digital Video Recorder, records digital broadcasts (dish network, Direct
TV or even your computer with an ATI card) (and the government listens to
phone calls on Condor?) Seems to me someone can invent a terabyte DVR that
records the digital stream from the dishes LNB instead of the channel tuner.
In this way all the channels can be viewed from the LNB recording. Imagine a
DVR that records 150 channels at one time. I'm sure the 100's of channels
are interlaced in some sort of time multiplexing. Granted under the current
hard drive limitations you might only get two hours of recording time.

I think DVRs are going to an internet, video on demand, model. The
machine can accumulate the shows over time so you would pay by how
soon you want the show to be available. If you are willing to wait for
the next broadcast to lots of customers it would be cheap, otherwise a
"right now" show would cost more.
My RTV 4508 can record of the net right now and that is 4 year old
technology. It is just waiting for conternt providers to release their
strangle hold on distribution.

| I have a dvr built into one of my dish network recvrs and a TIVO connected
to the other. Dish network also has a rcvr with two DVR's in one unit. My
TIVO can be remotely accessed by the internet so I can watch local programs
from anywhere.

| What you're talking about is theoretically quite simple to do- its
simply a high-resolution analog-to-digital recorder, but its
sensitivity and resolution requirements, as well as storage demands,
make it somewhat impractical.
Look for some surplus CIA/NSA signals intelligence equipment- that'll
do the job.

You would need at least a couple LNB's to achieve this.
The amount of storage space required would be HUGE.

| You would have to record the entire intermediate frequency (IF)
bandwidth of the satellite, some 500 MHz from the downconvertor
(950-1450 MHz). There are recorders for IF ranges (for spook work) but
usually quite smaller bandwidth. How much money are you fixing to spend?
