Abstract:
This paper describes an infrastructure that supports data
transforms and transmissions as part of multimedia
communications. The infrastructure is made up of a
specialized resource manager -- called media flow
manager -- which creates and manages media flows. A
media flow is the movement of a set of data -- through a
collection of media processing units -- from a set of
sources to a set of sinks. The paper describes the
programming interface presented to applications by the
media flow manager and the programming interface
between the media flow manager and media processing
units. It also describes how the media flow manager is
being used to build an audio/video messaging application,
and it describes the design and function of a particular
media processing unit -- a video transcoder -- used by the
messaging application.
