Modelagem de Ambientes Interativos Cientes de Contexto: Uma Abordagem Baseada nos Padrões MPEG-4 e MPEG-7

João Benedito dos Santos Jr.Edson dos Santos Moreira

This paper describes a scenario for interactive applications, based on the emerging MPEG-4 and MPEG-7 standards, that uses the context-awareness concepts in order to provide the necessary support to the development of more interactive and useful systems. At this point, new interaction criteria have been established from distribution of MPEG-4 media objects and MPEG-7 scene descriptions on network environments. MPEG-21 is being studied for applying to new multimedia requirements, considering multimedia objects as universal digital item. Contextawareness aspects have been extended and added for providing personalization on the interactive environment. The concept of interactive application profile is formalized and presented. As validating mechanism, an ITV (Interactive Television) application is presented as a case of study, focalizing how and which kind of contextual information could be used in the ITV environment, allowing the discussion about the main problems of the proposed modeling.
