The Perceptual and Attentive Impact of Delay and Jitter in Multimedia Delivery

In this paper we present the results of a study that examines the user´s perception-understood as both information assimilation and subjective satisfaction-of multimedia quality, when impacted by varying network-level parameters (delay and jitter). In addition, we integrate eye-tracking assessment to provide a more complete understanding of user perception of multimedia quality. Results show that delay and jitter significantly affect user satisfaction; variation in video eye path when either no single/obvious point of focus exists or when the point of attention changes dramatically. Lastly, results showed that content variation significantly affected user satisfaction, as well as user information assimilation.
