Abstract: | If commercial multimedia development continues to ignore the user-perspective in preference of other factors, i.e. user fascination (i.e. the latest gimmick), then companies ultimately risk alienating the customer. Moreover, by ignoring the user-perspective, future distributed multimedia systems risk ignoring accessibility issues, by excluding access for users with abnormal perceptual requirements. This paper presents an extensive examination of distributed multimedia quality. We define a model that considers multimedia quality from three distinct levels: the network, the media- and the content-levels; and two views: the technical- and the user-perspective. By manipulating both technical and user-perspective parameters, we examine the impact on quality perception at the three quality levels identified. Results show that: a significant reduction in frame rate does not proportionally reduce the user's understanding of the presentation, independent of technical parameters; the type of video clip significantly impacts user information assimilation, user level of enjoyment and user perception of quality; the display type impacts user information assimilation and user perception of quality. Finally, to ensure transfer of informational content, network parameter variation should be adapted; to maintain user enjoyment, video content variation should be adapted. |
