Abstract
Black terminated white runs of a binary video signal having a raster scan format with some scan lines of difference modulated picture elements and other scan lines of unmodulated picture elements are run length encoded using a block length multiple plus run length residue code format, whereby runs in excess of a predetermined block length are represented by block length multiple codes plus, for any runs which are not integer multiples of the block length, run length residue codes. Shorter black terminated white runs are converted into run length residue codes, and unterminated white runs are converted into end-of-line codes which distinguish between scan lines of difference modulated and unmodulated picture elements.
