We describe a systematic methodology for extending the audiovisual content description standards (MPEG-7 and TV-Anytime) with domain-specific knowledge descriptions expressed in OWL. The domain-specific descriptions of the audiovisual content metadata are completely transparent to applications and tools that use MPEG-7 and TV-Anytime, allowing them to use the domainspecific ontologies without a...

The present study investigated the cortical large-scale functional network underpinning audiovisual integration via magnetoencephalographic recordings. The reorganization of this network related to long-term musical training was investigated by comparing musicians to nonmusicians. Connectivity was calculated on the basis of the estimated mutual information of the sources' activity, and the corr...

In audiovisual composition, coupling montage moving images with music is common practice. Interpretation of the effect on an audioviewer's consequent interpretation of the composition is discursive and unquantified. Methodology for evaluating the audiovisual multimodal interactivity is proposed, developing an analysis procedure via the study of modality interdependent transient structures, expl...

Since its origins in the Fifties, Rai has always paid attention to pedagogical aspects of offer, consistent with Catholic inspiration, combining different genres and divulgation approaches. In first years history, Italian public television represented a “second school” for targets, producing iconic titles learning training. A particular branch educational approach content oft...

The goal of this study was to examine developmental change in visual attention to dynamic visual and audiovisual stimuli in 3-, 6-, and 9-month-old infants. Infant look duration was measured during exposure to dynamic geometric patterns and Sesame Street video clips under three different stimulus modality conditions: unimodal visual, synchronous audiovisual, and asynchronous audiovisual. Infant...

This study deals with uncertainty and attention in audiovisual speech perception. Subjects were exposed to audiovisual stimuli where independent variable was bivalent: either blocked to one ear or uncertainty about in which ear the next stimulus would appear. The hypothesis, that uncertainty would inhibit audiovisual integration was motivated by an earlier study (Öhrström et al, 2011) but these...

Multisensory interactions are well established to convey an array of perceptual and behavioral benefits. One of the key features of multisensory interactions is the temporal structure of the stimuli combined. In an effort to better characterize how temporal factors influence multisensory interactions across the lifespan, we examined audiovisual simultaneity judgment and the degree of rapid reca...

Numerous studies have demonstrated that the structural and functional differences between professional musicians and non-musicians are not only found within a single modality, but also with regard to multisensory integration. In this study we have combined psychophysical with neurophysiological measurements investigating the processing of non-musical, synchronous or various levels of asynchrono...

Some important developments in the area of multimedia applications lead to an open, Internet based environment, for multimedia. These developments include: (a) The popularity of the audiovisual content and its associated services (including the traditional TV and video services); (b) The advent of the digital media; (c) The availability of low-cost audiovisual content management devices; and (d...
