Abstract The fine grained scalable (FGS) coding is one of the most popular coding technologies in network video stream. In FGS stream, the base layer rate is an important parameter and should generally make a compromise between the number of beneficial clients and the efficiency of video coding. To maximize all clients ' perceived quality, the optimal partition algorithm for single FGS-coded video sequence is proposed. By analyzing the algorithms oriented FGS-coded stream proposed by Hsu et al, this paper first puts forward a method to build the R-Q function curve and proposes an algorithm to cut search space of the base layer rate. Second, according to the optimization problem of single sequence, the paper proposes the improved FGSOPT_N algorithm. At last, some illustration examples are given to demonstrate and compare the effect of algorithms.
