Regarding those multimedia user interface ideas, here are some examples to clarify. Regarding point one, a spatial selection is selecting a rectangle of a video. By itself, a spatial selection is a subrectangle for the entire multimedia object's duration: http://example.com/video.avi#xywh=160,120,320,240 (http://www.w3.org/TR/media-frags/#naming-space) A temporal selection is selecting, perhaps making use of the timeline, a portion or interval of a multimedia object. By itself, a temporal selection is for the entire movie's rectangle: http://example.com/video.avi#t=10,20 (http://www.w3.org/TR/media-frags/#naming-time) Combining those, selecting a rectangle of the multimedia object and an interval of it, simultaneously, is a spatiotemporal selection: http://example.com/video.avi#xywh=160,120,320,240&t=10,20 Point two, or bookmarking, is about placing points of interest on a multimedia object's timeline, for later use, without having to pause the multimedia user experience. Point three, observing the URI's for spatial, temporal and spatiotemporal media fragments, is about starting from one of those, as per <video src="http://example.com/ video.avi#xywh=160,120,320,240&t=10,20"/>, and being able to navigate to either larger rectangles, wider intervals, both, or to the video.avi object. Zooming also includes from a media fragment, such as http://example.com/video.avi#t=10,20, to a containing structural element, for example http://example.com/video.avi#id=chapter-1. Point four, videos also have tracks and, in such tracks, are possible structures beyond lists of chapters. Possible are structures like books, parts, chapters, pages, paragraphs and sentences. It is possible to select a structural element of a video. http://example.com/video.avi#id=chapter-1 (http://www.w3.org/TR/media-frags/#naming-name) With such structural tracks, people can traverse multimedia objects in structure-based ways, as per from a point in a multimedia object to http://example.com/video.avi#id=part-2. The fifth idea, is about client-side text searching into videos. Many document viewers and web browsers provide searching into documents for text occurances and that functionality is described as possible to extend into the multimedia objects in those documents. Client-side text-based multimedia search can be facilitated by processing the tracks that accompany multimedia objects, such as transcripts or captions, and by audio and natural language processing techniques.
