The robust delivery of video over emerging wireless networks poses many challenges due to the heterogeneity of access networks, the variations in streaming devices, and the expected variations in network conditions caused by interference and co-existence. By combining the continuous scalability of MPEG-4 fine-granularity-scalability (FGS) video coding with the robustness of variable modulation, a powerful method of video transmission is achieved that allows a video stream to be viewed with imperceptible degradation over a continuously changing wireless channel. In addition, sigmoid functions for throughput modelling for 802.11a networks are presented, and a game theoretic approach is suggested for further adapting the modulation and channel coding strategy to improve the video transmission performance under different wireless channel conditions.
