H.264/AVC is the latest video coding standard developed by MPEG and ITU. AVS is the latest video coding standard developed by China. The two new video coding standards will co-exist in the market in the future. So it is necessary to transcode the AVS format to the H.264/AVC format or vice versa. Because the AVS video coding standard is based on the 8x8 block and also uses the intra prediction t...

In this paper, the intra residual macroblock produced by H.264 is investigated. Based on its characteristics, an efficient two-layer coding scheme for the intra residual macroblock is developed. The rate-distortion performance for the proposed coding scheme is evaluated. Experimental results show that our algorithm can achieve better coding performance.

Several wireless network coding schemes apply either inter-flow traffic or intra-flow traffic, but not both. This paper proposes a novel batched network coding scheme to deal with both inter-flow and intra-flow traffics, which attempts to combine the advantages of both network coding approaches. Based on the idea in the well-known network coding scheme COPE, our batched network coding scheme al...
