The growing demands for advanced mobile multimedia let the wireless mobile Internet access be developed rapidly. The Mobile WiMAX (IEEE 802.16e) is capable of providing high data rate and flexible Quality of Service (QoS) mechanisms. However, one of killer applications, mobile streaming video service from mobile station (MS) to fixed internet network can't still avoid a traditional QoS degradation problem caused by unreliable mobile channel environment. The previous researches show that streaming video service based on downward cross-layer design over OFDMA channel has improved robust features to channel errors, but requires modifications of the existing schedulers, packet ordering, and channel allocation strategies in base station (BS). Now, our goal is that we develop a high error resilient and robust method to channel errors on the OFDMA mobile video device without the modification of conventional functions in WiMAX BS. In this paper, we introduce OFDMA channel aware error resilient video coding method using an upward cross-layer design. Through the extensive simulation results, we prove that the proposed channel-aware intra-refresh coding can recover video damages more efficiently than traditional intra-refresh one over OFDMA channel environment. This error resilience feature can be adapted to all types of streaming video server devices.
