“…A main component of interactive videos is a browsing functionality that enables a user to access a linear video in a nonlinear way. After partitioning a video into smaller segments [Mackay and Davenport 1989;Chang et al 2007], single scenes can be omitted [Chang et al 2007] or jumps to specific video parts are possible [Zhang et al 2006]. Zhang et al "allow proactive and random access to video content based on queries or search targets" [Zhang et al 2006] in interactive videos.…”

“…As a result, "users can select or play a segment with minimal search time" [Zhang et al 2006]. Mackay and Davenport state that it is possible to increase the level of interactivity "by allowing users to build, annotate, and modify their own environments" [Mackay and Davenport 1989]. -Nonlinear Videos consist of a set of scenes or video sequences, which are arranged in a library or as a walk-through in a graph structure [Kozuch et al 2000].…”

Hypervideos and interactive multimedia presentations allow the creation of fully interactive and enriched video. It is possible to organize video scenes in a nonlinear way. Additional information can be added to the video ranging from short descriptions to images and more videos. Hypervideos are video-based but also provide navigation between video scenes and additional multimedia elements. Interactive multimedia presentations consist of different media with a temporal and spatial synchronization that can be navigated via hyperlinks. Their creation and description requires description formats, multimedia models, and standardsas well as players. Specialized authoring tools with advanced editing functions allow authors to manage all media files, link and arrange them to an overall presentation, and keep an overview during the whole process. They considerably simplify the creation process compared to writing and editing description documents in simple text editors. Data formats need features that describe interactivity and nonlinear navigation while maintaining temporal and spatial synchronization. Players should be easy to use with extended feature sets keeping elements synchronized. In this article, we analyzed more than 400 papers for relevant work in this field. From the findings we discovered a set of trends and unsolved problems, and propose directions for future research.

“…For example, Mackay and Davenport examined the role of digital video in several interactive multimedia applications and concluded that video is an information stream that can be tagged, edited, analyzed, and annotated [13]. Later, Davenport et al proposed using metadata for home movie editing assistance [7].…”

Digital video is becoming increasingly ubiquitous. However, editing video remains difficult for several reasons: it is a time-based medium, it has dual tracks of audio and video, and current tools force users to work at the smallest level of detail. Based on interviews with professional video editors, we developed a video editor, called Silver, that uses metadata to make digital video editing more accessible to novices. To help users visualize video, Silver provides multiple views with different semantic content and at different levels of abstraction, including storyboard, editable transcript, and timeline views. Silver offers smart editing operations that help users resolve the inconsistencies that arise because of the different boundaries in audio and video. We conducted a preliminary user study to investigate the effectiveness of the Silver smart editing. Participants successfully edited video after only a short tutorial, both with and without smart editing assistance. Our research suggests several ways in which video editing tools could use metadata to assist users in the reuse and composition of video.

“…For example, there is considerable interest in the psychophysiology of emotion in social interactions (Levenson & Gottman, 1983, 1985. One can readily envision a workstation that could display a video record of, say, a couple's discussion of marital problems, synchronized with a transcript of the dialogue and plots of each partner's heart rate (MacKay & Davenport, 1989). What is needed, however, is a standard means to include time markers in textual transcripts, so that the transcript can be synchronized with the other data channels.…”
