A system for embedding positional data (20) in a video signal (18), the
system having a mobile object (4), a positioning receiver (10) associated
with the mobile object (4) for obtaining positional data (20) on the
mobile object (4) from a plurality of positioning satellites (6), a video
camera (16) associated with the mobile object (4) for creating the video
signal (18), an encoder (12) for receiving the video signal (18) from the
video camera (16) and the positional data (20) from the positioning
receiver (10) and modulating the positional data (20) within the video
signal (18) thereby creating a modulated video signal (22), and a video
recorder (15) associated with the mobile object (4) for storing the
modulated video signal (22) on a recording medium (14).
