Grounding on high correlation between neighboring blocks, finite state machine is employed both at encoder and decoder to reduce the number of bits required for encoding to enhance coding performance. Two extra intra prediction modes are created in our proposed method. Through these two modes, the number of bits required to denote the current block is greatly reduced and low bit rate can be achieved. According to spatial correlation, intra-coded residual prediction reduces residual block by neighboring residual block. In this paper, we combine finite state machine with intra-coded residual prediction to achieve better coding performance. Experimental results show that the proposed method can greatly improve coding efficiency of intra macroblock coding in H.264/AVC.
