We discuss a multimedia news system that we have developed in the Multimedia Information Research Laboratory at the University of Ottawa and beyond. The system consists of a production server for document authoring, a conferencing system for collaborative news article creation, a news database server with aging and archiving, and user sites. The goal was to have all components of the system communicating on OCRInet-an R&D ATM network in the Ottawa region. We provide an overview of the above components as well as discussing the news and video browsers implemented to facilitate browsing, searching, and extracting media from the database-in particular, video objects. To this end we introduce a novel way of representing and browsing video streams, called video-tiles.
