Project Abstract

   The aim of this project was to produce a microcontroller based video overlay system suitable for scientific documentation of a video source. Atmospheric pressure, temperature and 2 voltages must be measured by the device. After digitizing the inputs, the device displays the corresponding values together with the current time and user titling overlaid on the NTSC video input. User titling and commands are entered via a PS/2 keyboard.

The completed device
