they say they have an onboard compressor (details unknown to me) that
allows transferring 352x284x24x24fps (and the equivalent NTSC format)
at about 1.1MB/s over the ISA bus. Since even with the Meteor one
cannot hope to to much more than display/single frame capture with the
highest res. , I don't see this as a big problem. The interesting part
for me is the presence of a full duplex audio interface on the same
board, and the fact -- they say -- that both audio and video are
extremely simple peripherals using I/O ports only. No int, no DMA
--> extremely simple driver (good for didactical purposes).
