METHOD FOR ENTROPICALLY TRANSCODING A FIRST BINARY DATA STREAM INTO A SECOND COMPRESSED BINARY DATA STREAM, AND CORRESPONDING COMPUTER PROGRAM AND IMAGE RECORDING DEVICE

摘要

This method of huffman code conversion of a first set of binary data consisting of words to convert it into a second set of binary data compressed uses a huffman code to convert each word of the first set of binary data word in a transcoded. On the basis of a number of low order bits, it comprises the application of the following steps for each word ("s0000010110 ") of the first set of binary data: - subdivision (106) of the word in the first and second - words, the first word under - (" 10 ") comprising the b low order bits of the word and the second - word ("s00000101 ") comprising the other bits of the word, - application (108) of the huffman code to the second predetermined under - word in order to obtain a second - word transcoded (" 0001s01 "), and - preparation (110) of the word transcoded ("0001s0110 ") by concatenation of the first word under - (" 10 ") and the second - word ("0001 s01 transcoded »).
