Feature request: telemetry data(serial) encoded in video/sync #15

Closed GoogleCodeExporter closed 9 years ago

Please consider encoding telemetry serial stream into the video stream, that 
would be a long range, easy, one-way telemetry link.
Another minimOSD on the ground could extract the data.

Unfortunately the existing MinimOsd hardware cannot do this, as it is the 
responsibility of the Max7456 to output the video signal, and it onl modulates 
in the visible area.

Potentially this could be achieved with an aditional modem(s) on the audio 
channel to provide the serial link - however I doubt the bandwidth would be 
high enough to support for instance the artificial horizon.

Or alternatively just use Xbees as normal.

This is an enhancement, not a defect.

We could make something like this by modulating an audio signal. However we 
would need extra hardware to make it really effective.
