Robust Spiht Coded Video Transmission over Wireless Channels

There is a huge demand of video based services over internet and wireless networks, however, transmission of coded video bitstream over wireless channel is very challenging task. Various schemes have been proposed in the literature to combat the effect of transmission errors. In this paper joint source channel coding (JSCC) scheme is utilized to transmit the SPIHT (set partitioning in hierarchical tree) based Hybrid video coded bitstream such that the channel resources are efficiently utilized. The SPIHT is a bit-plane algorithm that generates embedded bitstream. The embedded bitstream and forward error correction (FEC) codes are exploited to form JSCC that minimize the effect of channel errors. The strength of the scheme is that the quality of the reconstructed video is improved without increasing the transmission bandwidth. Simulation results show that the proposed scheme gives up to approximately 25 dB of improvement over the system which does not incorporates FEC.
