The invention discloses a
video streaming business code rate self-adaption method based on
online study. The method comprises the steps of firstly establishing a
wireless video streaming business
system frame, and generating different
code rate levels to be selected in a way of using scalable video coding as a source end coding mode; then establishing a utility function, and using a discounted overall MOS value to represent QoE, so as to serve as an optimization goal of a
code rate self-adaption mechanism; and establishing an action value function space, using an
online study algorithm to perform iterative operation, updating the action value function space and a confidence coefficient
distribution function according to the information of immediate MOS value and
packet loss probability fed back by a terminal in each period, and accordingly selecting the proper video
code rate for transmission. According to the method, the QoE is used as the optimization goal of self-adaption of the
video streaming code rate, the optimal solution of code rate adjustment is iteratively approached by the
online study algorithm, the link congestion can be effectively relieved, the user QoE is improved, and the
computation complexity is relatively low.
