IPML: Extending SMIL for Distributed Multimedia Presentations

Jun Hu and Loe Feijs

Abstract This paper addresses issues of distributing multimedia presentations in an ambient intelligent environment, exams the existing technologies and proposes IPML, a markup language that extends SMIL for distributed settings. It uses a powerful metaphor of play, with which the timing and mapping issues in distributed presentations are easily covered in a natural way.

Distributing Multimedia Elements to Multiple Networked Devices

Maddy Janse, Peter van der Stok, and Jun Hu

Abstract. Two applications from different projects in which video content is distributed over in-home networked devices are presented. Multiple displays and ambience objects are used to display interactive content. Major issues concern the design of appropriate evaluation methodologies, the use of perceived video quality to achieve efficient resource allocation and the subjective role of content.

User Experience Evaluation of a Distributed Interactive Movie

Jun Hu, Maddy Janse, Hyun-joo Kong

The effect of presenting a distributed interactive movie at different levels of control and distribution on the end user’s fun and presence experience was studied. The results suggest that an increased level of end-user control on the flow in the video increases the level of the user’s experience and impacts the feeling of presence significantly. The effects of distribution are less clear and are very much depending on the presentation devices and the content modality. These results are discussed in terms of the measurement instruments and the experimental design, and suggestions are made for further research.
