  Abstract

Currently, multimedia is taking a new turn due to the rapid process of IT industry. During these processes, it is essential to process multimedia in real time in the wireless communication system based on mobile network and fixed network and in the wire communication system due to fiber cable and xDSL. One of the them is effciency of system and the portion of entropy encoder in system efficiency of HDTV is greater than other part. So, in this paper the optimal memory allocation algorithm combines the merit of Huffman encoding which is superior in simultaneous decoding ability and Lempel-ziv that is distinguished in execution of compress is proposed to improve the channel transmission rate and processing speed in the compressing procedure and is verified in the entropy encoder of HDTV. The entropy encoder system using proposed optimal memory allocation algorithm has a weak point increasing 28% in size than established one but induces a decreasing in case external RAM. Also, we comfirms that the compressing ratio for moving pictures is superior than Huffman encoding and LZW.
