Abstract

Today, more and more events of interest all over the world such as press conferences, rock concerts, soccer matches, breaking news, etc. become available on the Internet as multimedia content like pictures, video and audio streams, or web pages. These events are bound not only to a certain topic but also to their location and time. The questions is how recent multimedia events from all over the world can be made available and "experienceable" to people considering their different personal contexts such as their location and interests. Not least because the content on today's WWW infrastructure is not explicitly published along with contextual information such as time and location, the information access via the big search engines --- apart from wellknown deficiencies handling non-textual content --- must remain context-insensitive. In this paper, we present the MediÆther multimedia event space, a decentralized peerto-peer infrastructure that allows to publish, to find and to be notified about multimedia events of interest. The paper defines an event model along which multimedia events, their location, time and media data are published in the space. Thereby, MediÆther provides a suitable basis for multimedia applications such as personalized multimedia sports and news tickers or multimedia city tours that consider user interests and context like time and location to create a "personal experience."
