Abstract :
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.
