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)
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).

What is claimed is: 1. A method comprising: receiving a video signal from a video camera, the video signal depicting a recording subject; receiving positional data from a positioning receiver, the positional data being for a location of an object, the recording subject within view of the object; an
What is claimed is: 1. A method comprising: receiving a video signal from a video camera, the video signal depicting a recording subject; receiving positional data from a positioning receiver, the positional data being for a location of an object, the recording subject within view of the object; and encoding the positional data into a video portion of the video signal to produce a modulated video signal, the modulated video signal capable of being demodulated to present the video signal and the positional data. 2. The method of claim 1, wherein encoding the positional data into a video portion of the video signal to produce a modulated video signal comprises: modulating the video signal with the positional data by altering the luminance of the video signal. 3. The method of claim 1, wherein encoding the positional data into a video portion of the video signal to produce a modulated video signal comprises: modulating one or more frames of the video signal with the positional data in a substantially invisible manner. 4. The method of claim 1, wherein encoding the positional data into a video portion of the video signal to produce a modulated video signal comprises: selecting one or more fields of the video signal for modulation; and modulating one or more selected fields of the video signal with the positional data. 5. The method of claim 1, wherein receiving positional data from a positioning receiver further comprises receiving supplemental data regarding an aspect of the object from an auxiliary source; and wherein encoding the positional data into the video signal to produce a modulated video signal comprises encoding the positional data and the supplemental data into the video signal to produce a modulated video signal. 6. The method of claim 5, wherein the supplemental data is selected from a group of data comprising at least one of: a temperature of an engine, a speed of a vehicle, and a rotation of a camera lens. 7. The method of claim 1, further comprising: broadcasting the modulated video signal to a playback device. 8. The method of claim 1, further comprising: storing the modulated video signal on a recording medium. 9. The method of claim 8, wherein the recording medium is at least one of a VHS tape or a digital versatile disc (DVD). 10. The method of claim 1, wherein the object is a mobile object. 11. The method of claim 8, wherein the mobile object is an object selected from a group of objects consisting of a vehicle, a train, a tank, a watercraft, an airplane, a missile, and the video camera. 12. The method of claim 1, wherein the positional data is GPS location data. 13. A method comprising: accessing a modulated video signal, the modulated video signal including positional data encoded into a video portion of a video signal, the positional data being for a location of an object; decoding the modulated video signal to obtain the positional data; and presenting the modulated video signal for display and the positional data for reproduction. 14. The method of claim 13, wherein presenting the modulated video signal comprises: synchronously presenting the modulated video signal for display and depicting the location of the object on a map at a time the modulated video signal was recorded. 15. A method comprising: accessing a modulated video signal, the modulated video signal depicting a recording subject, the modulated video signal including positional data and supplemental data encoded into a video portion of a video signal, the positional data being for a location of an object, the supplemental data being supplemental information regarding the recording subject; decoding the modulated video signal to obtain the positional data and the supplemental data; and presenting the modulated video signal for display and the positional data and the supplemental data for reproduction. 16. The method of claim 15, wherein presenting comprises: synchronously presenting the modulated video signal for display and the supplemental data for reproduction, and depicting the location of the object on a map at a time the video signal was recorded. 17. A system comprising: a video camera to provide a video signal depicting a recording subject; a positioning receiver to provide positional data on a location of an object, the recording subject within view of the object; and an encoder, the encoder to receive the video signal from the video camera and the positional data from the positioning receiver and modulate the video signal to include the positional data in a video portion of the video signal a substantially invisible way. 18. The system of claim 17, further comprising: a video recorder to record the modulated video signal on a recording medium. 19. The system of claim 17, wherein the positioning receiver is in a fixed position on the object. 20. A machine-readable medium comprising instructions, which when executed by a machine, cause the machine to: receive a video signal from a video camera, the video signal depicting a recording subject; receive positional data from a positioning receiver, the positional data being for a location of an object, the recording subject within view of the object; and encode the positional data into a video portion of the video signal to produce a modulated video signal. 21. The machine-readable medium of claim 20 further comprising instructions, which when executed by a machine, cause the machine to: store the modulated video signal on a recording medium. 22. The method of claim 13, wherein presenting comprises: presenting the modulated video signal for display on a display device and the positional data for reproduction on a presentation device. 23. The method of claim 15, wherein presenting comprises: presenting the modulated video signal for display on a display device, the positional data for reproduction on a presentation device, and the supplemental data for reproduction on a supplemental device.
