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.
