Is there an efficient, quick and simple example of doing differential b/w image compression? Or even better, some simple (but lossless) streaming technique which could accept a number of frames as input?

I have a simple b/w image (320x200) stream, displaying something similar to a LED display, which is updated about once a second using AJAX. Images are pretty similar most of the time, so if I subtracted them, result would compress pretty well (even with simple RLE). Is something like this available?
