MPEG-4 FGS video coding can perform video transmission with adaptation to channel bandwidth variation on the network. However, binary zero-run-length coding used by FGS decreases its coding efficiency in the lower bit-plane. In this paper, we propose a new coding scheme improving coding efficiency in the lower bit-plane. Based on the distribution of a significant coefficient, each bit is classified into two groups. At the same time, information that raises picture quality higher than any other coefficient is coded first. Simulation results show that this proposed scheme improves the coding efficiency up to more than 1.06%, and achieves 0.2dB gain in terms of average PSNR.
