Abstract
We use the term integrated media to encompass both modeled media, and recorded and live natural media. We believe that an integrated media framework is important because natural and modeled media are complementary and are most useful when integrated. Natural media has the property of vividness (since nature is so rich), while modeled has the property of compactness and malleability (since computers are so flexible). While existing multimedia systems have little, if any, support for modeled media, omitting them is abandoning what computers do best, namely computing, mixing, and enhancing.

MediaFlow supports modeled and natural media and the spectrum in between. It is based on the concepts of high-level data types and of omni-grain continuous dataflow. (By "continuous," we simply mean that time is indefinitely refinable.) We treat visual, audible, and gestural flows uniformly. The result is a design that provides uniformity, minimality, and orthogonality and hence, the ease of programming integrated media applications.
