The data compression technique described in the previous article and referred to as the "Change Block Skipping" (CBS) code has a very fast execution time implemented in software, but its compression ratio is not as good as some other techniques. Another technique, the run length method, has just the opposite problem. A hybrid technique takes advantage of the processing speed of the CBS code and the compression ratio of the run length code. In effect, the hybrid technique is a compromise approach.
