Multimedia Adaptation for Hybrid Environments


Accessing informationa anytime, anywhere, with any device is primary demand of today's information oriented society. The real question is however, how to bring services and multimedia to terminals to be used anywhere. Our approach to multimedia adaptation offers a way to adapt multimedia presentations to all kinds of terminals used over mobile or fixed networks. The original presentation is compressed or scaled based on user's terminal parameters and network bandwidth. Special emphasis has been placed on how to deliver a variety of media to mobile terminals. In this research a multimedia adaptation schema called a Media Wrapper is proposed. The profiles from client and network are presented using CC/PP profiling which is a tag-based language for delivering profile information. The main task of the Media Wrapper is to decide the format and size of the adapted presentation based on the knowledge from these profiles. The second task of the Media Wrapper is to adapt original presentation to an appropriate output format using different codecs, compression methods and scaling tools. These tools and methods are controlled by Adaptation Agents which are implemented as intelligent software agents. Keywords: multimedia adaptation, mobility, software agents, CC/PP profiling
