A method and system provide additional detail to a video sequence in response to user input. The system allows a user to generate a link from an anchor point in a source video sequence to a target point in a destination video sequence. A video sequence may be constructed from a single video clip or a video composite comprised of video clips and other video composites. Video composites may be used as objects to create video sequences. Links between video source and destination points may span one or more levels in a hierarchical video structure. A user may configure the anchor point and target point to be at different locations within corresponding video sequences.

The invention relates to generating digital video sequences, and more particularly to generating digital video sequences having multiple levels of detail and responsive to user input.
With the advent of many different digital video systems, many types of interactive video have been developed. One type of interactive video is the inclusion of optional side trips. This type of interactive video allows users to follow a link out of the currently playing video to watch an alternate video sequence. At the end of the video sequence, or upon user input, the video presentation returns to the original video departure point and continues to play.
Expanding on the concept of optional side trips in video, detail on demand video comprises one or more base video sequences. Each base video sequence has one or more optional alternate video sequences. Each alternate video sequence provides additional details related to the base video sequence. During video playback, users may select the alternate video sequence to view this additional detail.
The present invention will be described with reference to the drawings, in which:
FIG. 1 illustrates a hierarchy of video clips and video composites arranged on a layout space;
FIG. 2 illustrates a method for creating links between video sequences for detail on demand video according to an embodiment of the present invention;
A simple, flexible interface for creating detail on demand video allows users to create detail on demand video without having to deal with the complexities associated with freeform hypervideo or nonlinear video editing. In an embodiment, the interface is comprised of a two-dimensional layout space for arranging video clips. Each video clip is represented by an icon, a still picture, or a reduced representation. The order of the video clips in the layout space determines the final chronological order of the video sequence.
The interface presented is adaptable for use on any general purpose computer or other information processing device. This includes desktop and portable computers, personal digital assistants, embedded computing systems, information appliances, cell phones, and any other device capable of processing digital information. The computer may optionally include user input devices, such as keyboards or pointing devices, and output devices, such as graphic displays devices and video recording devices.
The interface supports the rapid development of a hierarchical video structure. Unlike other video editing applications, an embodiment of the invention allows the grouping of several video clips into a video composite. Although the video composite is a sequence of video clips, the user may manipulate the video composite as a single, unified object. Video composites may be manipulated in the same manner as single video clips. In this manner, video composites are used as building blocks to create video sequences or optional alternate video sequences. During playback, the component video clips of a video composite are played in the order in which they are grouped in the video composite.
