A data compression method utilizing a series of rules which are chosen for best compressing selected data. Rules are provided for converting each datum into a binary value, and encoding this binary value into a variable-width bit field. Rules are provided for automatically increasing or decreasing the binary field width which encodes the next data value, based on the current field width and encoded data value. An escape code is used to increase the field width for the next encoded value. A rule for efficient run-length encoding of repeated values or codes may also be included.

[ What is claimed is:] [14.] A circuit, comprising processing means for compressing a sequential stream of digital input values by converting input data into input values and then into binary, digital channel codes in a plurality of fields, so that in the absence of any explicit additional channel codes or rules which specify the field width to be used for the next channel code, the field width comprising the number of binary digits in the channel code depends exclusively and implicitly on both the preceding input value and the field width of the channel code for the preceding input value.
