Use of pre-interleaving for video streaming over wireless access networks
We present an FEC-based end-to-end error control scheme for video streaming over wireless access networks, considering both bit errors and packet-loss. We propose a novel robust video streaming system in which an interleaving is applied to the compressed bitstream before channel coding. The application of such pre-interleaving is able to significantly improve the error-combating performance of video streaming because the adoption of this pre-interleaving can simultaneously satisfy different requirements arising from both channel coding and source coding. Experimental results demonstrate the improved performance of the proposed pre-interleaving scheme, especially in the case of highly bursty and regular channel errors.
