METHOD AND SYSTEM FOR EMBEDDING DEVICE POSITIONAL DATA IN VIDEO SIGNALS

摘要

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