8K Time into Space: Web-Based Interactive Storyboard with Playback for Hundreds of Videos

8K Time into Space uses the extreme size and resolution of emerging modern large-format displays to present a video sequence as an array of shorter "snippets" so that the entire event can be seen at once. A TV program or movie is subdivided into short, repetitive sequences that each represents successive segments of the longer program. This "storyboard" is then arrayed across a large, touch-sensitive display to present the entire movie at once. A viewer can indicate any part of the presentation and the display will enlarge the sequences near that point in time. Or, the movie can occupy the entire screen at a point selected from the array. The 8K, 33-million pixel screen stresses the number of live video windows that graphics controllers and HTML5 can support, so we developed a novel scheme that treats each segment as a sprite, thus allowing interaction and 15fps (frames per second) playback with stability that corresponds to human perception. This paper describes the video playback architecture. Moreover, we applied this system to an actual TV program to confirm the availability.
