Video Question

[David G Anderer]

A question that's come accross my desk:

One of our users wants to use a Sun with a video disc player (or some
other type of video input).  The Sun will control the player and display
images (or full-motion video) on the screen in a window with
computer-generated text overlayed.

An alternative is to hook a monitor to the video disc player and pipe the
Sun text as an overlay for display there.

Possible?  What hardware do we need for this?

Thanks.
