摘要：

Recent advances in technology have resulted in a significant growth in wireless communications, which have resulted in a strong demand for reliable transmission of video data. The challenge of robust video transmission is to protect the compressed data against hostile channel conditions while bringing little impact on bandwidth efficiency. In this paper, using macroblock (MB)-based segmentation results, we propose a framework for the positioning of resynchronization markers such that the image quality of foreground can be improved at the expense of sacrificing the unimportant background. Experimental results demonstrate that this scheme significantly improves the subjective quality of video sequence for robust video transmission.
