Are the tx/rx locations fixed or moble?
Fixed.
Grumpy Mike, correct me if I am wrong but my next options if I choose not to go the ARM processor would be to use a digital output camera with my thread's stated specifications and use that in junction with the screen from adafruit or to find a pre-fabricated 1.8 inch (or 2 inch) lcd screen with a built in RCA to digital conversion.
