We propose a new H.264 video broadcasting scheme with retransmission feature using feedback information. Our scheme efficiently maps the video data partitioning technique of H.264 onto the QoS control features of the 802.11e based MAC layer. The proposed scheme effectively suppresses the feedback messages which can potentially cause significant increase of network traffic and the processing overhead at the access point. Simulation results show that the significant overall video service quality enhancement can be achieved. Another advantage of the proposed scheme is that it uses the application level retransmission requests and therefore it can be applied without any modification to the existing MAC protocol.
