Well you should be able to do it on  small ARM processor, but you've always
got to take transmission time into account - those pesky satellites do tend
to move about quite a bit :)

There's also the format used by the NOAA weather satellites - simple and

Good question - "medium" was a deliberately vague term as it will also
depend on the camera and available data rates etc.

I was hoping we might be able to move on from analogue SSTV now.. we should
be able to achieve much better quality images,,,as you suggest the challenge
would be to do the digital encoding on board the spacecraft without using
lots of power but, as mentioned, - if they can do it on a tiny payload
hanging beneath a small helium balloon then it should be possible to do
something similar on a spacecraft even a 1U cubesat!
