Mullender, S. Multimedia systems will allow professionals worldwide to collaborate more effectively and to travel substantially less. But for multimedia systems to be effective, a good systems infrastructure is essential. In particular, support is needed for global and consistent sharing of information, for long-distance, high-bandwidth multimedia interpersonal communication, greatly enhanced r...

The areas of television, telecommunication, and information technology are converging, new application areas are arising and new services are being established. Aside from the traditional delivery channels, computer networks play an increasing role in providing the new services. An important part of these services is based on video. However, in order to develop and establish such services, the ...

The exceptional advent of interactive multimedia applications in our days has led to the need for their exploitation for educational, among other, purposes. In this work, we present the design and implementation of a multimedia annotation environment for young children. This environment was developed to provide children of ages 4 to 8 with the opportunity to reflect upon and annotate episodes f...

This paper presents Bigger Bits, an interactive multimedia learning environment that teaches students about VLSI within the context of computer electronics. The system was built with COSMOS (Content Oriented Semantic Modelling Overlay Scheme), which is a modelling scheme that we developed for enabling the semantic content of multimedia to be used within interactive systems.

We propose analytic model of the delay of the Slotted ALOHA protocol with Binary Exponential Backoff (BEB) as a collision resolution algorithm in mobile multimedia networks. We verify the proposed analytic model using the computer simulation. In numerical results, our proposed method show correct analytic model and has better performance results than previous methods in mobile multimedia networks.

The proliferation of multimedia on the World Wide Web has led to the introduction of Web search engines for images, video, and audio. On the Web, multimedia is typically embedded within documents that provide a wealth of indexing information. Harsh computational constraints imposed by the economics of advertising-supported searches restrict the complexity of analysis that can be performed at qu...

OBJECTIVE To evaluate a clinic-based multimedia intervention for diabetes education targeting individuals with low health literacy levels in a diverse population. RESEARCH DESIGN AND METHODS Five public clinics in Chicago, Illinois, participated in the study with computer kiosks installed in waiting room areas. Two hundred forty-four subjects with diabetes were randomized to receive either su...

Applying technologies has recently caused language education to undertake influential modifications. Hence, this study tried to investigate the impact of using technology in form of multimedia on improving grammar knowledge of Iranian high school students and also examined their attitudes toward multimedia-based mode of instruction. To do so, three intact classes of lower intermediate students ...

Distance education can be very effective use of instructional materials with visual, auditory, audiovisual and multimedia content. Visual content can be in the form of text, drawings, pictures, graphics and models, and the like. Auditory facilities are oral presentation or a speech, musical accompaniment, different sounds, etc.. Audiovisual content combine visual and auditory content, usually i...
