hi Nick:

At APS we use video feed from various devices.  Most of the feed are from MEDM
displays operating on either sun workstations or LINUX or PC windows.
 We use frame grabbers to grab the video.

There are small embedded PC we use from Diamond systems.   I have tested with
LINUX and MEDM and plan to switch some of the WINDOWS based to LINUX running fedora.

It is very easy to fix these machines arround your facilty and I can assure you
that the quality of the doisplay will be far far superior tahn anything you do
with VIDEO unless you use  HDTV signals.

Also another posibility is to run web browsers in full screen modes arround the
facility on any old machines and make them auto refresh or even use java based
tools...


good luck
mohan
