“…The design philosophy of these works is to represent a binding as an explicit object that could be manipulated by separating the control and management concerns from the functional aspect of a given application. This is particularly the case of multimedia middleware where a multimedia binding type is constructed as a component composition [27][28][29] that could also be seen as a kind of nested bindings from protocol to the media session.…”

Abstract. This paper proposes a two-layer component-based middleware framework that copes with the complexity of managing and constructing efficient and useful SIP-based home services. In the first layer, the device integration framework overcomes the heterogeneity of media home devices by providing protocolindependent components that reify the underlying devices. At the second layer, the binding framework allows constructing open mobile media bindings between SIP and non SIP communication protocol endpoints including media home devices. The openness of our framework is motivated by the need of constructing highly flexible home services such as context aware adaptation, session mobility, media session enrichment and QoS. Our framework is implemented as part of a context-aware adaptive middleware on top of the OSGi platform and an illustrative use case is shown.

“…UbiQoS [10] is a middleware implemented using Java-based mobile agents to exploit Video-on-Demand services with dynamic QoS adaptation. TOAST [11] middleware platform provides component-oriented CORBA support for adaptive distributed multimedia applications, adjusting QoS parameters, i.e. to vary the achievable latency and throughput.…”

Abstract--The CORBA Audio/Video (A/V) Streaming Service has been designed to implement and integrate open distributed multimedia applications. In this paper, a set of impairments resulting of the original A/V service are identified. To overcome such limitations, we propose an extension to the specification of the A/V Streaming Service. It defines a flexible architecture creating a framework that simplifies the implementation of applications handling audio/video flows. To evaluate our service extension we develop middleware objects of an application to control and manage uncompressed video data flows with strict time restrictions. Empirical results obtained by executing this application are also presented and discussed.

“…The Toolkit for Open Adaptive Streaming Technology (TOAST) [8] investigates the use of open implementation and reflection to ease the development of adaptation strategies. However, it remains to the responsibility of the application developer to deal with resource and application monitoring, reconfiguration decisions and their implementation, which is a pretty heavy task.…”

Abstract. Distributed multimedia applications are very sensitive to resource variations. An attractive way for dealing with dynamic resource variations consists in making applications adaptive, and even self-adaptive. The objective is to grant applications the ability to observe themselves and their environment, to detect significant changes and to adjust their behavior accordingly. This issue has been the subject of several works; however the proposed solutions lack flexibility and a high-level support that eases the development of adaptive applications. This paper presents PLASMA, a component-based framework for building multimedia applications. PLASMA relies on a hierarchical composition and reconfiguration model which provides the expected support. The experimental evaluation shows that adaptation can be achieved with a very low overhead, while significantly improving QoS of multimedia applications as well as resource usage on mobile equipments.
