Abstract
Today, there is a strong trend towards networked multimedia devices.
However, common multimedia software architectures are restricted to
perform all processing on a single system. Available software
infrastructures for distributed computing -- commonly referred to as
middleware -- only partly provide the facilities needed for supporting
multimedia in distributed and dynamic environments. Approaches from
the research community only focus on specific aspects and do not
achieve the coverage needed for a full-featured multimedia middleware
solution.
The Network-Integrated Multimedia Middleware (NMM) presented in this
thesis considers the network as an integral part. Despite the inherent
heterogeneity of present networking and device technologies, the
architecture allows to extend control and cooperation to the network
and enables the development of distributed multimedia applications
that transparently use local and remote components in combination. The
base architecture of this middleware is augmented by several
middleware services that especially aim at providing additional
support for developing complex applications that involve mobile users
and devices. To this end, previously not available services and
corresponding abstractions are proposed, realized, and evaluated. The
performance and applicability of the developed middleware and its
additional services are demonstrated by describing different realized
application scenarios.
