Interfaces for interactive audio-visual media browsing

Abstract

In this demo, we present new interfaces for interactive navigation in continuous, time-based multimedia files, such as video recordings. In contrast to common techniques for multimedia skimming, our approaches enable users to interactively navigate audio files along the timeline and support time-synchronized browsing in both audio as well as visual data streams.

Supporting speech for annotation and asynchronous discussion of multimedia presentations

“…At the time of writing, the first experimental version of an audio search engine for archived lectures has just been integrated into the lecture portal at the authors' institution, yielding quite promising results (Hürst & Deutschmann, 2006). We hope to be able to use the ASR engine of that system for our own architecture in the future: whenever a new annotation is uploaded to the server it will be processed by the ASR tool and a transcript will be produced and stored together with the annotation.…”

“…Also, all previously played segments are visualized in order to keep track what has been listened to before (see Figure 5). More technical details on this interface component are described in (Hürst et al, 2006). If users do not wish to have the visualization or audio feedback during scrolling, both features can be deactivated in the configuration menu.…”
