Methods and apparatus for interactive point-of-view authoring of digital video content
First Claim
1. An interactive, electronic method for exploring and analyzing visual data using a plurality of traversal records, each of the traversal records comprising a time-based sequence of frames, each frame being a spatial subset of the visual data, the method comprising:
- displaying an abstract map of the visual data;
plotting a plurality of markers, each of said markers associated with one of said traversal records, in a corresponding plurality of locations on the map; and
playing back the corresponding traversal in response to interactive selection of a desired one of the markers.

Abstract
The present invention provides electronic methods and apparatus for interactively authoring, sharing and analyzing digital video content. Methods for authoring include displaying visual data, defining each traversal as a time-based sequence of frames and annotating and storing a record of the traversal and its associated audio records. Defining the traversal includes interactively panning the visual data by positioning an overlay window relative to the visual data and zooming in or out by resizing the overlay window. In alternative embodiments, the visual data may be displayed in a rectangular layout or a cylindrical layout. The methods are practiced using an integrated graphical interface, including an overview region displaying the visual data, a detail region displaying current data within the overlay window, and a worksheet region displaying a list of previously stored annotated traversal records. In a further aspect, the worksheet region list of annotated traversal records is published in a web document accessible via network using a standard HTML browser, and further annotations may be added by a community of network users. Analytical methods are also provided in which data markers corresponding to traversal records are plotted against an interactive abstract map enabling users to shift between levels of abstraction in exploring the video record.
