| Abstract |
Due to the heterogeneity and complexity of user
environments and multimedia services and content in the
communication domain, adaptation is of a paramount
importance. Adaptation decisions at the different stages of
service authoring and delivery to the end user depends on
contextual information that characterises the situation of
entities involved in the interaction between the user and the
service. This paper presents how the Adaptation Manager
processes and models contextual information. The use of
different standards and technologies such as MPEG
standards, Description Logics and OWL are explained. The
paper illustrates how the Adaptation Manager complements
the decision making framework defined by MPEG-21 DIA |
