QoE for Multimedia Content Sharing
In
recent years, it has been realized that the success of multimedia
services or applications not only depends on Quality of Service (QoS)
parameters but also relies on the analysis of the entire user
experience (UX). The relevance of this paradigm ranges from IPTV or
video-on-demand systems for distributing and sharing professional TV to
user-generated content over the web. To obtain a pleasurable user
experience far more aspects than QoS have to be taken into account.
Major challenges in this context include the identification of relevant
UX factors and the quantification of their influence on Quality of
Experience (QoE). In particular, context awareness and assessment of
users’ expectations play an essential role. This is further justified
by the emergence of new multimedia enhancement techniques, notably 3DTV
and Free Viewpoint. Future Internet architectures under current
research are also promising on the possibility to accommodate protocols
and policies that take QoE issues into consideration. Consequently,
acquired knowledge on the context and on identified parameters
affecting users’ experience could be used to improve media delivery.
