The new international video coding standard H. 264/AVC has significant improvements in coding efficiency and error robustness in comparison with the previous standards such as MPEG2

H. 263

MPEG4 part 2. But improved coding efficiency comes at the expense of adding complexity to coder/decoder. The research shows the conclusion that the calculation complexity of H. 264/AVC codec has several times as the previous standards

so as to get real time codec we must find high-effective optimization methods. The paper introduces the optimization solutions on software and hardware. The experimental outcomes are shown to achieve real time decoding with the optimized decoder.
