Delivering MPEG-4 Based Audio-Visual Services investigates the
different aspects of end-to-end multimedia services; content
creation, server and service provider, network, and the end-user
terminal. Part I provides a comprehensive introduction to digital
video communications, MPEG standards, and technologies, and deals
with system level issues including standardization and
interoperability, user interaction, and the design of a distributed
video server. Part II investigates the systems in the context of
object-based multimedia services and presents a design for an
object-based audio-visual terminal, some of these features having
been adopted by the MPEG-4 Systems specification. The book goes on
to study the requirements for a file format to represent
object-based audio-visual content and the design of one such
format. The design introduces new concepts such as direct streaming
that are essential for scalable servers. The final part of the book
examines the delivery of object-based multimedia presentations and
gives optimal algorithms for multiplex-scheduling of object-based
audio-visual presentations, showing that the audio-visual object
scheduling problem is NP-complete in the strong sense. The problem
of scheduling audio-visual objects is similar to the problem of
sequencing jobs on a single machine. The book compares these
problems and adapts job-sequencing results to audio-visual object
scheduling, and provides optimal algorithms for scheduling
presentations under resource constraints, such as bandwidth
(network constraints) and buffer (terminal constraints). In
addition, the book presents algorithms that minimize the resources
required for scheduling presentations and the auxiliary capacity
required to support interactivity in object-based audio-visual
presentations. Delivering MPEG-4 Based Audio-Visual Services is
essential reading for researchers and practitioners in the areas of
multimedia systems engineering and multimedia computing, network
professionals, service providers, and all scientists and technical
managers interested in the most up-to-date MPEG standards and
technologies.
