IEEE Proceedings, Special Issue on Multimedia Signal Processing and Technology, 1998 (invited paper, to appear)
Abstract
Content creation, editing, and searching are extremely time consuming tasks that often require substantial training and experience, especially when high-quality audio and video are involved. "New media" represents a new paradigm for multimedia information representation and processing, in which the emphasis is placed on the actual content. It thus brings the tasks of content creation and searching much closer to actual users and enables them to be active producers of audiovisual information rather than passive recipients. We discuss the state-of-the-art and present next-generation techniques for content representation, searching, creation, and editing. We discuss our experiences in developing a Web-based distributed compressed video editing and searching system (WebClip), a media representation language (Flavor) and an object-based video authoring system (Zest) based on it, and large image/video search engines for the World-Wide Web (WebSEEk and VideoQ). We also present a case study of new media applications based on specific planned multimedia education experiments with the above systems in several K-12 schools in Manhattan.
