ABSTRACT:
The disclosed data compressor receives an input stream of data characters and provides a corresponding stream of output codes. The compressor generates a sequence of numerically increasing output codes corresponding to numerically increasing contiguous segments of a detected run of the same data character. Non-run characters of the input stream are transmitted directly in synchronism with incrementing the codes of the code sequence. In one embodiment, the number of characters in the run segments are stored together with the respective codes representing the segments. In later encounters of a previously processed run, the stored data is accessed and the stored codes corresponding to the run segments are output as appropriate.
