Abstract
Abstract — In this paper, we present the design, implementation and evaluation of a utility-based network adaptation system for the delivery of MPEG-4 video over time-varying networks such as wireless networks. The system comprises a number of algorithms that can be programmed to support application-specific adaptation in the network or at its edges. By exploiting video content and user preferences, an online utility generator can dynamically formulate bandwidth utility functions and scaling profiles that capture applicationspecific adaptation. The utility generator employs a video content classification algorithm to speedup processing and an adaptive prediction algorithm to keep dynamically generated utility functions meaningful over network adaptation timescales. Network adaptation is based on a utility-fair bandwidth renegotiation algorithm that realizes profile-based media scaling. The signaling system efficiently delivers utility functions and scaling profiles to network adaptation agents.
