Since I have problems in getting my posting trough I asked to this friend of

The problem I have to solve is the recording of a image sequences taken from
a camera mounted on a robot together with data coming from odometry and
sonars.  That tape will be our test set for robot navigation algorithms. 
I hope that someone of these newsgroups readers has solved the problem of
recording images synchronized with some data.

PROBLEM: 

I want to record some information supplied from a rs232 together with images
onto a videorecorder.  The problem I have to solve is the recording of a
image sequences taken from a camera mounted on a robot together with data
coming from odometry and sonars.  That tape will be our test set for robot
navigation algorithms. I'm quite sure that someone of these newsgroups 
readers has solved the problem of recording images synchronized with some
data.  

POSSIBLE SOLUTIONS: 

 audio:
 I could use something like a FSK modem but it seems that it works only up to
 2400 baud.  I'd like going up to 9600.  

 video: 
 I'd also prefer to record that info on the vertical interval time (so
 that the info is really in sync with the image) but I'm open to any
 suggestion.  

WHAT I NEED:

Pointers to something on the market (I'm sure that someone is making
a machine to record EEG or ECG onto a VHS recorder);

- or -

Pointers to something I could assemble;

- or -

Hints how to build my own encoder.
