The paper investigates TCP-friendly video streaming over wireless channel using forward-error-correction (FEC). A FEC scheme is used as an intra-protection control based on Hamming code. Coded BPSK scheme is applied over AWGN wireless channel to be robust against frequent packet loss. For this purpose, we propose variable frame rate based on TCP-friendly rate control (VFR-TCP) model. The model estimates the predicted frame rate for MPEG video streaming. Quality of service (QoS) is also accounted for the predicted quantizer scale Q if the network throughput is assumed to be equal the available bandwidth. Simulation results show that the VFR-TCP model increases tolerance to packet loss due to channel bit errors and achieves a good quality
