Our system to be targeted for is a 4 way video capture system.
We want to simultaneously capture to disk (with hardware processing to say
MPEG 2 or 4 prior to saving to disk) 4 video inputs.
This is not a surveillance thing where 4 way PCI capture cards compose one
video stream from 4 by placing the camera contents in ΒΌ of the same
screen/image.
The system is meant to capture the 4 streams away from base over a long
period of time so its a performance v storage issue v power.
We could use a high performance PC with 4 PCI solots/video capture cards,
and a terrabyte or two of storage but that is not practical.
We are thinking of using a moderate capability PC (say mini ITX 1.3-1.7GHz)
with 4 way video capture , hardware compression on card and DMA to the
harddrive/s. Ideally we would use one capture card with 4 channels but they
would need to work simulataneously, not time/resource slicing/overlay.
Alternatively we would use 4 PCI Video capture cards (need PCI riser with
mini ITX board).
Any thoughts or recommended ng/discussion groups for this?
