A circuit and method for decompressing video subsequent to its prior compression for transmission or storage. The circuit assumes that the original video generated by a raster input scanner was operated on by a two line one shot predictor, coded using run length encoding into code words of four, eight, or twelve bits and packed into sixteen bit data words. This described decompressor, then, unpacks the data by joining together the sixteen bit data words and then separately the individual code words, converts the code words into a number of all zero four bit nibbles and a terminating nibble containing one or more one bits which constitutes decoded data, inspects the actual video of the preceeding scan line and the previous video bits of the present line to produce depredictor bits and compares the decoded data and depredictor bits to produce the final actual video.
