Auction Based Optimal Subcarrier Allocation for H.264 Scalable Video Transmission in 4G OFDMA Systems

Free registration required

Executive Summary

In this paper, the authors present a price maximization scheme for optimal OFDMA subcarrier allocation for wireless video unicast/multicast scenarios. They formulate a pricing based video utility function for H.264 based wireless scalable video streaming, thereby achieving a trade-off between price and QoS fairness. These parametric models for scalable video rate and quality characterization are derived from the standard JSVM reference codec for the SVC extension of the H.264/AVC, and hence are directly applicable in practical wireless scenarios. With the aid of these models, they propose a novel auction based framework for revenue maximization of the transmitted video streams in the unicast and multicast 4G scenario.
