Abstract

In this paper, we propose a dynamic transmission method for scalable video with unequal error protection (UEP). Forward error correction (FEC) is used in the UEP scheme. FEC codes, such as Reed-Solomon (RS) codes, are allocated to different layers of scalable video according to their importance. The UEP scheme is applied on each group of pictures (GOP) with taking account of the data size fluctuation of GOPs. The proposed method dynamically adjusts the number of packets according to the source data size of each GOP in order to achieve similar channel code rates for different GOPs. Meanwhile, the buffer management is also considered to limit transmission delay on the sender side. Simulation results show that the proposed method can make significant improvement of average PSNR of reconstructed video in a wide range of channel coding rate and packet loss rate compared with the conventional UEP scheme.
