Paper Abstract

In this paper, we propose a new selective regional slice coding method for H.264 that can improve the quality of decoded video. We can get better performance when we compare to conventional coding methods. And it also serves better shapes in a picture by removing adjacent to macroblock edge. In this paper, flexible macroblock ordering (FMO) is used for transmitting the slice. FMO is used for sliced coding in packet loss environment. We propose the way to modify to improve slice coding in the sequence. The experiment result of the proposed method shows the improvement of quality and also error robustness. The result of implementation about such system is improved 0.11dB to 1.52dB when we compare to non-slice coding in the experiment.
