User heterogeneity and priority adaptive multimedia broadcast over wireless

Abstract

This paper presents an adaptive SVC (scalable video coding) multimedia broadcast framework for the heterogeneous wireless mobile receivers with varying display resolutions, battery constraints, channel conditions, and service subscription priorities. In a bid to achieve optimal performance two variants of optimizations, namely, Subscriber-count Maximizing Adaptive SVC Rate and Energy Saving (SM-ASRES) scheme and Revenue Maximizing ASRES (RM-ASRES) are formulated. In SM-ASRES, the optimization of multimedia encoding parameters is focused toward maximizing the number of served subscribers based only on user capability and channel conditions. On the other hand, RM-ASRES additionally considers subscribers' priority for multimedia broadcast adaptation. Energy saving at the user equipment is a result of time slicing approach at the transmission stage. As compared to the conventional broadcast schemes, the proposed user adaptive framework shows an appreciable improvement in quality of user experience and increased energy saving for hand-held mobile users, along with an increased revenue when employing RM-ASRES.Index Terms-User adaptive multimedia broadcast, scalable video coding, heterogeneous users, energy saving, quality of user experience, revenue maximization, subscription priority.

User-Centric Energy-Efficient Multimedia Multicast/Broadcast Solutions: A Survey

“…The feedback from the UEs helps the service provider's transmitter to allocate resources adaptively in order to improve QoE and earn increased revenue. Technological solutions based on this framework have balanced the tradeoff between: UE energy saving and QoE [120,121]; UE energy saving and price [122]; as well as revenue and served subscriber count [123].…”
