Hey, a man after my own heart - I'd have used datamatrix though ;-)

The only question I have (and this is not a put down) is why?

Any encoding on the video image is going to reduce the quality of the
barcode image and thus make it a little harder to read and apart from
being cool not many people can read 2D barcodes by eye.

Personally I would think encoding the NMEA string into APRS beacons (or
the like) onto the audio track would be the way to go. That way it could
be done without any processing power in the car - just a GPS, APRS encoder
(can be a simple as a PIC or OpenTracker) and a camcorder with a line/mic
input.

If you are going to process the video you could render the GPS data as a
human readable graphic overlay (think speedometer, compass heading,
lat/long, etc) onto the video... but why not include a 2D barcode too.

Anyway 'way cool',
Simon.
