Preference-based adaptation of multimedia presentations for different display sizes

Abstract

The increased availability of electronic devices with multimedia capabilities has resulted in a dramatic growth in the usage of multimedia presentations. In this paper, we present a framework for automatic generation of layouts for multimedia presentations for different screen resolutions. We develop a heuristic to find the layout for a screen of given resolution in polynomial time. The heuristic achieves 92-98% performance compared with the exhaustive search for different screen sizes. The execution time of the heuristic is as low as 15 seconds for a presentation of 100 media files whereas the exhaustive search takes an average of 6 hours.

Hypervideos and Interactive Multimedia Presentations

“…It can be noted that videos, audio files, text, and images are part of many multimedia presentations (e.g., Adjeroh and Lee [1995] and Nimmagadda et al [2009] The layout of multimedia presentations is defined by the locations and the start times of the objects" [Nimmagadda et al 2009]. Prerendered static multimedia presentations allow VCR actions while interactive multimedia presentations feature additional navigational structures.…”

“…These have to be resolved (e.g., Blakowski et al [1992] and Abdelli [2008]). -Spatial relationships and layout: Fixed or varying spatial layouts with overlapping media elements need to be defined, which may also change over time (e.g., Chung and Shih [1997] and Nimmagadda et al [2009]). -User interactions: "A multimedia presentation whose content is predefined before rendering is called a static multimedia presentation.…”
