- W1981226617 abstract "We consider a point-to-point delay-stringent video communication system. To reduce the fluctuation of the coded data packet sizes for efficient wireless transmission, we adopt the intra-refreshment and adaptive slice partitioning for video encoding. We model the delay-constrained video transmission with the proposed video coding and slicing scheme using an MDP model, and compute the optimal coding and modulation scheme corresponding to each channel state and the encoding and transmission delay using the value iteration algorithm. Extensive simulations based on real videos show that the MDP-based transmission scheme significantly reduces the transmission cost and enhances the quality of the reconstructed video sequences compared with the non-adaptive transmission scheme, which transmits constant number of transmitted symbols for all slices. Simulation results also show that the intra-refreshment and adaptive slice partitioning significantly enhances the quality of the reconstructed video sequences compared with the video coding without intra-refreshment." @default.
