    ABSTRACT: This paper proposes a new MPEG-2 AAC Huffman decoding algorithm which is designed to find multiple symbols in a single search. The analysis and experimental results show that the computational complexity of the proposed method is lower by more than 46% when compared with those of the up-to-date methods.

    ABSTRACT: Combination of multiplication-free one-bit transform based block estimation with the diamond sparse search pattern is presented is this paper. Unification of sparse search patterns with low-bit representation motion estimation methods are rarely investigated and therefore one-bit transform based approaches are executed using full-search approach mostly. Our experiments show that such a combination can be carried out with acceptable performance fall.

    ABSTRACT: This paper describes a digital convergence platform (DCP), which is implemented based on the MPEG-21 multimedia framework. The DCP is a newly proposed solution in this research for the convergence service of future home multimedia environment. The DCP is a common platform designed to have the feature of configurability, via means of S/W, which is needed for the convergence service of diverse digital media. A distributed peer to peer service and transaction model is also a new feature realized in the DCP using the MPEG-21 multimedia framework. A prototype DCP is implemented to verify its functions of multimedia service and transactions. The developed DCPs are networked with IP clustering storage systems for the distributed service of multimedia. Successful streaming services of the MPEG-2/4 video and audio are verified with the implemented test-bed system of the DCP.

    ABSTRACT: This work presents a new structure of MPEG-4 AAC encoder. The proposed encoder directly shapes quantization noise distribution according to the energy distribution and thereafter performs adjustment of the offset level of the noise distribution to meet the target bit rate. The direct noise shaping and the bit rate matching scheme significantly alleviate the problem of processing burden of the conventional encoder related with the precise modeling of the psychoacoustics and iteration intensive quantization.
