Video transmission often suffers from various errors over wireless networks. Due to errors, the discarded link layer packets impose a serious limitation on the maximum achievable throughput over wireless channel. To face this challenge and to improve the overall TCP-Friendly video throughput, this paper proposes a new robust error-model for MPEG-4 video stream over a point-to-point wireless network. A noisy wireless channel is modeled for random bit errors causing packet loss with some restrictions on the design parameters including packet length, modulation format, and channel SNR. By this model, efficient bandwidth access from wireless network is achieved via a hybrid scheme of channel coding which acts as a Forward Error Correction (FEC), and Automatic Repeat Request (ARQ) protocol at a radio link layer. The new results show that a good video quality of service (QoS) can be estimated in terms of play-out frame rate (in frames/sec) when a maximum channel coding throughput is achieved. Further, this proposed model can improve drastically the end-to-end video quality at high wireless channel errors and low-delay of ARQ scheme.
