Abstract
Optimizing wireless bandwidth utilization is one of the numerous challenges in wireless IP multimedia systems design. This paper describes and evaluates the performance of a novel Application Level Framing protocol for efficient transmission of H.264 video over error-prone wireless IP links. The proposed ALF protocol introduces an innovative loss spreading scheme for video streaming services which is based on (i) a bandwidth-efficient adaptive H.264 video fragmentation and (ii) an unequal-interleaved protection for improving FEC efficiency. Both video fragmentation and interleaving are coordinated in a frame-based granularity providing bounded end-to-end delays. Performance evaluation results show that the proposed protocol allows graceful video quality degradation over error-prone wireless links while minimizing the overall bandwidth consumption and the end-to-end latency. © IFIP International Federation for Information Processing 2004.
