Video streaming over wireless links involves two basic needs: rate reduction transcoding and error control channel coding. For traditional transcoding systems, the performance is usually proportional to the system complexity. In this paper, we propose a novel transcoding scheme, which can achieve better performance with reduced system complexity. Coupled with a simple joint source-channel bit allocation approach, the proposed transcoding can accurately throttle the source coding rate so that there is sufficient bandwidth left for channel coding to correct channel errors in wireless links. Simulation results demonstrate that the proposed video streaming system can achieve a good performance without much increasing in system complexity.
