New forms of interaction became possible from the díssemiiiation of the interactive vídeo technology. The possibility for using multimédia objects in modem applications has proveu to be a bónus and the xve want to provi de ways in which the user ean internet with multimédia objeets, while the presentation is occurring, with features that go beyond the regular eontrols of a VCR (Video-Cassette Recorder). Furthermore, the presentation of the video ean be rnodified by events happening in the surrounding euvironment. lu this seeuario, the environment may require the reilesigu of the user interface and the retargeting of the elementanj streams parameters in order to match specifie requirements and features of tlw environment (application, media, netieork and terminais). Several new techniques and standards have beeu produeed in order to allow for the development of nexo applications; hoxoever, some potential new interaction fornis are still unexplored. The main objective of this thesis is to present a proposal for Modelling of Context-Aware Interactive Environments Based on Standards of the MPEG (Moving Picture Expert Group) Family, using the UML (Uuified Modelling Lauguage) and considering the user actious from contextual inforniation like a way to ease its interaction with interne tive applications. The 7vork desenhes a seeuario for interactive applications, based on the emerging MPF1G-4 and MPEG-7 standards, that uses the context-awareness concepts in order to provi de the necessary support to the development of more interactive and usefid systems. At this point, new interaction cri teria have beeu 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 multimédia requirements, considering multimédia objects as universal digital item. Context-awareness aspeets hai>e beeu extended and added for pwvidiug persoualization ou the interactive eirvironment. 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 inforniation could be used in the ITV environment, allowing the discussion about the main problems of the proposed modelling.
