- Abstract
- In UMA environments, because of the heterogeneous networks and terminals, flexible video adaptation, performed according to network conditions and terminal capabilities as well as user preferences, is required to maximize user experience and ensure Quality of Service (QoS). We propose an adaptation method of scalable video using MPEG-21 Digital Item Adaptation (DIA) that provides systematic solutions in choosing an optimal adaptation operation to given constraints and supports inter-operability of the adaptation. In a framework for delivery, adaptation and consumption of scalable video, the proposed method was simulated under dynamic network conditions, terminal capabilities and user preferences.
