Abstract :
Standard video codecs, such as MPEG1/2/4 are based on DCT and MC. Since they require high computational complexity, they consume a lot of energy. So, they are not suitable for mobile terminals. On the other hand, the video coding using 3D hierarchical tree structure has been proposed with low computational complexity. But its drawback is low compression efficiency. This work proposes a new video coding and presents evaluation results. It can attain both low computational complexity and high compression efficiency.
