<p>The present invention relates to data compression apparatus comprising means (320) for receiving an input string of data words, storage means (330) for storing selected data words, comparison means for comparing the input data words with the stored data words, token generating means (370) for generating tokens representing input data words which are identical to stored data words, and means for combining the tokens with input data words which are not identical with any stored data words to form a compressed string of data words. According to the invention the data compression apparatus is characterised in that the storage means comprises means for storing input data words which are not identical to any stored data words so as to increase the number of stored data words. <IMAGE></p> |
