Abstract
In this paper, we propose an approach that combines statistical multiplexing and Multiple Description with Forward Error Correction (MDFEC) coding to make the optimal use of server bandwidth, taking into account the dynamically evolving content (complexity) of the different videos being streamed by the server, and path bandwidths and loss rates experienced by the users. We formally pose and analyze the complexity of the MDFEC statistical multiplexing problem, and present a dynamic programming based polynomial-time algorithm to compute the optimum solution. We also evaluate the performance of the proposed approach against those that do not use either MDFEC or statistical multiplexing, based on the experimental results obtained from real video sequences. Besides optimizing the overall distortion across all users, our approach is quite effective in providing differentiation between user groups with significantly different path bandwidths, particularly when a weighted version of our approach is used.
