Thanks for your reply.
I do not know exactly what a framegrabber extension card will / can
do, but the system I need must be very compact, light weight and
consume minimum power.
So far I have determined that DVR's (some, perhaps not all) store the
data to a HDD, rather than RAM.
The end use for this system is to record live video during a model
rocket flight, hence the need for small size and light weight.
I envision using a small single board CCD that outputs NTSC,
sufficient RAM to store 30-45 sec. of video, and whatever intermediate
electronics are required to get the encoded / compressed video data
into and out of the RAM.
Thanks again for your comments.
