Abstract
An integrated framework of optimal rate allocation for video coding is presented in the case of transmission over wireless channels without feedback channels. For a fixed channel bit rate and finite number of channel coding rate, the proposed scheme can find the optimal source and channel coding pair and corresponding robust video coding scheme such that the expected end-to-end distortion of video signals can be minimized. With the, assumption that encoder has the stochastic channel information, the proposed scheme takes into account robust video coding, channel coding and packetization, error concealment techniques altogether. Simulation results show the accuracy and optimality of the proposed method
