Data over video stream

Hy

Is it possible to send data over a video Signal? So on one side of the Arduino the raw video signal is coming in. The Arduino does attach some information. And than a second Arduino could detect this data in the Video signal and process it... How can I achieve this?

Thx Andy

Very low bit-rate data in blanking?

Hmm wouldn't this disturb the video signal itself. You should still get a clean Video without interference....

Like teletext, you send the data in BLANKING.

Didn't know that this is working this way, ok so this would be a solution. Now I do need the components...

Sorry, I assumed you were talking about analogue composite PAL/NTSC/SECAM style video.

If you are, get used to something like an LM1881

Yes it would be a PAL signal and yes I just read about the LM1881 hmm lets see how I can deal with that...
