“…These cues, while not central to understanding, play an important role in the detection of deception [3]. Numerous studies have shown that degrading video quality can have cognitive and perceptual consequences for viewers [4,5].…”

In various types of interactions, individuals may attempt to determine whether their communication partners are being honest or deceptive. Judgments of honesty rely, in part, on assessments of nonverbal behavior. With the increased use of videoconferencing technology, many traditionally faceto-face interactions now take place over sub-optimal video connections. In these connections, reduced spatial and temporal video quality may affect the ability to detect whether others are lying or telling the truth. In the current study we examined the effects of varying levels of temporal and spatial distortion on lie detection performance. Consistent with earlier work, we found that a slight distortion of the video signal impaired lie d etection performance. Surprisingly, performance improved when the video was severely spatially degraded.

“…Low video frame rates are common in recent mobile multimedia services especially in streamed unicast services. Frame rates as low as 5 fps and lower were avoided at all costs in a desktop computer based study by Pappas & Hinds (1995). Another study, conducted by Apteker et al assessed the watchability of various types of video at different frame rates (30, 15, 10, 5 fps).…”

This chapter provides an overview of the key factors that influence the quality of experience (QoE) of mobile TV services. It compiles the current knowledge from empirical studies and recommendations on four key requirements for the uptake of mobile TV services: (1) handset usability and its acceptance by the user, (2) the technical performance and reliability of the service, (3) the usability of the mobile TV service (depending on the delivery of content), and (4) the satisfaction with the content. It illustrates a number of factors that contribute to these requirements ranging from the context of use to the size of the display and the displayed content. The chapter highlights the interdependencies between these factors during the delivery of content in mobile TV services to a heterogeneous set of low resolution devices.
