简介
Wireless video transmission suffers errors from the dynamic wireless environment. 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 enhance the overall TCP-Friendly video throughput, this paper proposes an MPEG packet loss model which is based on Forward Error Correction (FEC) over wired-to-wireless channel. Within this model, a FEC packet level scheme is used to act as an inter-protection control, which is based on Reed-Solomon (RS) code with the aim of bringing a robust transmission against frequent packet loss. Further, a BPSK scheme is applied for an Additive White Gaussian Noise (AWGN) wireless channel. By using this model, the predicted frame rate for MPEG video streaming can be estimated. Quality of Service (QoS) in terms of frame rate and the quality factor are evaluated for the predicted quantizer scale. The numerical results demonstrate that the proposed scheme improves the QoS of video transmissions in the presence of high wireless channel bit errors.
