Abstract
A digitizer board is disclosed of the type which can be coupled to the data bus of a standard personal computer to enhance the data processing capabilities of the computer. The digitizer board is adapted to receive a composite video signal input which includes information for reproducing an image, e.g., television images. The composite video signal also includes a composite synchronization signal which carries information for synchronizing reproduction of the image from the composite video signal. The digitizer board responds to the composite video signal to digitize the image signals such that the digitized image signals may be readily stored, transmitted or reproduced using standard digital data processing apparatus.
