In distributed applications, a group of multiple application processes have to send and receive multimedia messages by using the high-speed network. The multimedia message at the application level is decomposed into multiple smaller packets which are transmitted in the communication system. In this paper, we discuss the atomic and ordered delivery of messages at the application level rather tha...

In this paper we will explore security threats and attacks possibility and security solution for Application Server of IP Multimedia Subsystem(IMS-AS). The SIP Application Server is an important entity of IP Multimedia Subsystem (IMS) because applications providing value added services are deployed on the Application Server. The SIP Application Server is triggered by Serving Call State Control ...

We examine the performance of high-bandwidth multimedia applications over high-speed wide-area networks, such as the vBNS (Internet2). We simulate a teleimmersion application that sends 30 Mbps (2,700 datagrams per second) to various sites around the USA, and measure networkand application-level loss and throughput. We found that over the vBNS, performance is affected more by the packet-rate ge...

The composition of interactive multimedia titles is a challenge for all advanced multimedia authoring tools. When non-interactive titles were specified by aligning the media items on a temporal axis such as time lines or tracks, now interactive multimedia titles require a non-linear temporal model. Thus, authoring becomes more complex, and the structure of a title is more difficult to visualize...

The paper is a presentation of the current state of development for the Atlas of Physiology and Pathophysiology (Atlas). Our main aim is to provide a novel interactive multimedia application that can be used for biomedical education where (a) simulations are combined with tutorials and (b) the presentation layer is simplified while the underlying complexity of the model is retained. The develop...

The use of real-time techniques in new application fields, such as multimedia computing, has extended classical algorithms to more dynamic environments, introducing the problem of controlling and adapting the quality of service provided by an application. In this paper, we investigate the possibility of integrating application-dependent adaptation strategies with reservation techniques for hand...

We present the current state of the technology used for web multimedia educational simulator development. The main aim is to provide novel interactive multimedia application that can be used for biomedical education where (a) simulations are combined with tutorials, and (b) the presentation layer is simplified while the complexity of the model is kept beneath. The development of the multimedia ...

Multimedia transmissions over wireless sensor networks may provide valuable information of the monitored field, enhancing monitoring and control applications. However, multimedia streaming can considerably shorten the expected lifetime of battery-operated sensor networks due to the large amount of information to be transmitted from multimediaenabled source nodes. On the other hand, multimedia d...

Nowadays a steadily increasing amount of multimedia content is generated and requires storage in digital libraries. Current research focuses on identifying user needs to make relevant information available through semantically enhanced retrieval techniques. In this context the already complex task of retrieving multimedia content on a semantic level is further complicated by right management an...

This paper examines the design and implementation of ParcBIT, a multimedia GIS CD-ROM presenting the information required for the development of a Master Plan for a Technological Park in the island of Majorca (Spain). The CD-ROM is the information resource of an international competition for Master Plan proposals in which world leading architects took part. Environmentally conscious planning is...
