High Quality with Low-Cost H.264/AVC Interframe Mode Decision Algorithm for Wireless Network

Abstract

In order to apply high quality video communication in the mobile device with limited power and communication bandwidth, especially in wireless communication, an efficient solution for video communication should be proposed. So, the latest video coding standard, H.264/AVC, is used for Video Codec in mobile terminals. However, the H.264/AVC standard is much more complex than previous video coding standards because of utilizing improved inter and intra predication modes. In order to use the Video Codec in mobile devices, a high quality with low-cost interframe mode decision algorithm based on reducing redundant candidate modes and reducing reference frames for each block type by using coded macroblock (MB) information is proposed in this paper. From the results of our experiments, on average, our proposed algorithm can reduce 70.28% encoding time and decrease 0.97% bit rate (BR) with little quality loss.
