Abstract

Traditional multimedia systems deal with only a few basic media:text, graphics, audio and video. However, many other types of media,such as ultrasound, infrared and RF signals, can be represented bystreams of data samples and processed within multimedia applications.In this paper, we introduce some of these new media domains andidentify interesting opportunities enabled by theirsoftware-based processing. We also describe our SpectrumWare testbedfor experimenting with these new media types and report on ourexperience to date.We believe that the time has come to broaden the scope of‘multimedia’ to include any form of sampled information. Advances inprocessor and analog-to-digital conversion technology have brought rawsample streams within the grasp of desktop computers and media processingsystems. Coupling these new media types with software-based processingallows the construction of virtual devices that can handle differentsample sources, modify their behavior based on information extractedfrom the media, and transform information between media domains.
