“…The use of implicit user-hints in resource control has been applied to a wide range of multimedia applications, with each scheme being limited in scope to a specific domain. For example, Kulju et al [1] investigated user hints in the context of video streaming, while Ott et al [2] focused on its use within their own 3D landscape. In addition, recent work in collaborative workspaces has investigated how hints may be used in order to dynamically control the use of reliable multicast [3].…”

This paper presents a bandwidth sharing scheme for group video conferencing. The key features of the scheme are the monitoring of implicit user-hints and message passing, which are used by each client in order to identify and report their interest in other group members. Information about user interest is then used by each video sender in order to adjust their frame-rate, resolution, and ultimately bandwidth consumption in an attempt to satisfy the current interests of the receivers. A general framework and initial prototype are presented together with experimental results.

“…We proposed a software architecture as a solution to build such applications, and implemented a framework based on this architecture. 6 In this section, we outline the important aspects of our architecture. The principal pattern of interaction between components in our architecture for multimedia application software is a service contract between a service provider and a service consumer.…”

While current work in multimedia session mobility has usually been concerned with maintaining the network connection of a mobile client, we believe that session hand-off between terminal devices or service providers is essential as well. The ability to simultaneously utilize multiple display devices permits the evolution of new application scenarios that will ease the restrictions of session playback on a portable multimedia device. At the same time, the ability to transparently re-bind a multimedia service provider, as we shall show, allows the system to scale well with respect to the number of mobile clients, and will improve utilization of the broad-band network infrastructure of the future.In this paper, we consider the problem of providing multimedia services to mobile clients, from the viewpoint of designing applications and systems that support session mobility. We present a software architecture for multimedia services that supports session hand-off between service providers, and allows operating parameters of all components of the session to be altered as part of the hand-off. We describe a user interface that simplifies initiating session mobility, while taking into consideration display device capability. We discuss the system support that is necessary, and describe the implementation of our ideas within our software architecture.

The SCUBA protocol [Z] represents early work in this area, describes the architectural components for the class of schemes discussed in this paper.…”

In this paper, bandwidth-sharing schemes controlled by user-interest are presented as an approach to eficient use of resources in a collaborative workspuce environment. Two schemes for group videoconferencing are presented and evaluated. Monitoring of user-behavior and message passing to adapt video bandwidth allocation to user needs are key features of both schemes, in which each user's client reports interest in other users to enable them to determine their relative importance. Experimental results using a protoQpe implementation to sample user-behavior show that one scheme is bener suited for high, and the other f o r low bandwidth-limit scenarios. Measurements also show that the message passing will not add a substantial amount of bandwidth.
