QoE Modeling and MPEG-21 DIA Multimedia Framework in Telecommunication and Broadcasting Convergence

摘要

With the increased consumption of multimedia content, users have become more eager to access multimedia content anytime, anywhere, and via any device. In this paper, we present a quality of experience (QoE) model for a broadcasting and telecommunication convergent environment and propose applying this QoE model to the MPEG-21 DIA (Digital Item Adaptation) Framework. We propose setting up a "Media Decision Taking Engine " (MDTE) in the MPEG-21 DIA Framework, and present a design for the MDTE and an explanation of how it works. As such, by making use of the proposed MDTE, an optimal multimedia content adaptation/distribution system can be made available even in a diverse network environment.
