Dear Listmembers,

I received the following message concerning analog to video conversion
that I summarized a week or three ago. I thought it was important enough
to share.

My initial posting (edited):

A colleague has an application for a device that takes an analog
signal (a pressure or flow waveform, for example) and converts it to a
form that can be mixed with a genuine video signal (from a video camera,
for example) so that the waveform is visible down at the bottom of each
frame. Ideally the device would have controls to vary the placement of
the waveform within the video frame and the timing. The waveform would
scroll across to the right, showing n cycles (where n is another
controllable feature), then disappear when it gets to the right side and
start over. Alternatively, the current time could be represented in the
middle of the screen with the waveform itself moving to the left.

Thanks,
--Sandy Stewart

Try an Australian company LAMONT MEDICAL SYSTEMS.
They make an EEG system which records EEG & video on VCR
They sold us the module for mixing analog & video signals minus the EEG
& signal analysis modules.
