Over the past several years there has been a considerable amount of research within the
field of quality of service (QoS) support for distributed multimedia systems. To date, most of …

Increases in processor speed and network and device bandwidth have led to general
purpose workstations being called upon to process continuous media data in real time …

A novel database system service called a playout management service, which performs
multimedia presentations was proposed by the authors recently [1st Int. Workshop on …

One of the major requirements of distributed multimedia applications is the need to maintain
often complex, real-time synchronization constraints. More specifically, it is necessary to be …

Continuous media such as audio and video pose new challenges to all parts of
multipurpose operating systems. We discuss issues related to CPU scheduling, memory …

The most notable characteristic of continuous-media data is the existence of timing
constraints. To handle such data appropriately some system support for resource …

The paper proposes a dynamic QOS control scheme using a processor reservation system.
In our scheme, a system allocates processor capacity for each application, then the …

Mission-critical multimedia applications such as advanced command and control are
dynamic and criticality-driven. Taking into consideration the application criticality as well as …

The paper describes recent progress in research on database system support for executing
multimedia presentations. It proposes the general concept of reactive playout management …

In an interactive multimedia environment that handles multiple sessions dynamically, a
mechanism for controlling the QOS among sessions is very important. It is, however, di cult …
