Abstract

L'invention concerne un procédé de compression d'une page HTML consistant: à analyser le contenu, les étiquettes, les attributs de valeur et les attributs de données d'une page HTML, à comprimer le contenu, les étiquettes et les attributs de valeur de façon indépendante au moyen du codage de Huffman, et à coder séparément les attributs de données sans utiliser une technique de codage de Huffman.
