<p>A method for entropic transcoding of a first sequence of binary data of words to transcode into a second compressed sequence of binary data uses a predetermined entropic code involving a variable-length of the encoded words to transcode each word of the first sequence of binary data into a transcoded word. Based on a predetermined number B of low-order bits, the method includes application to each word of the first sequence of binary data: subdivision of the word into first and second subwords, wherein the first subword includes the B low-order bits of the word, and the second subword includes the other high-order bits of the word, application of the predetermined entropic code to the second subword to obtain a second transcoded subword, and obtaining the transcoded word by concatenation of the first subword and of the second transcoded subword.</p> |
