Abstract. A method is proposed for improving the efficiency of multimedia data compression standards. To improve the efficiency of entropy coding within the standard, the hierarchical enumerative coding (HEnuC) is used, including the coding method of Lynch-Davisson (LD) and enumerative coding of bounded integers (EBI). Experimental study of the proposed solutions is performed using MatLab package for several images. The presented results demonstrate better compression than achieved with the simple entropy coding (Huffman method). The developed approach is recommended for the use in telecommunication systems for storage, transmission, and processing of multimedia data.
Keywords: hierarchical enumerative coding (HEnuC), entropy coding, compression rate, lexicographic index, multimedia data compression
