Abstract
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 is encoded by converting black terminated white runs into block length multiple plus run length residue message codes, non-terminating black picture elements into individual message bits, and unterminated white runs into end-of-line message codes. Different end-of-line message codes are provided for the unterminated white runs of difference modulated and unmodulated picture elements to distinguish between the scan lines of difference modulated and unmodulated picture elements on a scan line-by-scan line basis, but otherwise the encoding is carried out in the same way for both the difference modulated and unmodulated picture elements.
