摘要

由于视频帧的高分辨率，高清晰度视频(HDV)的传输必须面对大尺寸的视频包。使用灵活的宏块排序(FMO)来控制不同网络类型的视频数据包的大小会导致比特率开销。在本文中，我们提出了一种改进的FMO算法，可以有效地降低比特率开销。在该算法中，基于变换系数的相似性，将所有mb分组到SGs中。实验结果表明，与传统的FMOs相比，该算法可以显著降低比特率开销。

FMO bitrate overhead reducing for High Definition Video streaming over packet networks

The transmission of High Definition Video (HDV) has to confront large size video packets due to the high resolution of video frames. The usage of Flexible Macroblock Ordering (FMO) to control the size of video packets for different network types causes bitrate overhead. In this paper, we propose an improved FMO algorithm that can efficiently reduce the bitrate overhead. In the proposed algorithm, all MBs are grouped in SGs based on the similarity of the transformation coefficients. Experimental results show that our algorithm can reduce the bitrate overhead significantly as compared with conventional FMOs.
