Recent advances in technology have caused 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 results from a simplified macroblock-based segmentation algorithm, we propose a framework called content-based resynchronization for the effective positioning of resynchronization markers such that the image quality of foreground can be improved at the expense of sacrificing unimportant background. We do this because, in applications such as video telephony and video conferencing, foreground is typically the most important image region for viewers. Experimental results demonstrate that this scheme significantly improve the perceptual quality of video sequences for robust video transmission.
