....file format to the user. Any application reading the file with read( would see the flat version; any conversion from the hierarchical Cheerio format would happen transparently. Some work has been done in this direction, but not in the context of parallel 67 file I O. The Zodiac project [NCS97, CMNY98] has built a media file system that supports e#cient inserts. 7.3 Research of theoretical interest In addition to the systems projects described above, there are three areas of theoretical research that may prove fruitful. Describing the Cheerio file format The structure of the Cheerio file s ....

....need for interchange mechanisms for importing, exporting, and sharing movies and parts of movies. Users employ a variety of tools to create content, and it should be as easy as possible to move media and structure objects betxveen Creator and other applications. Some form of revision control (see [7,8]) is also required, particularly during the Updating phase. SMIL 2.0 (http: wwv.v3.org TR smi120 ) has evolved to provide a rich set of tags for controlling timing relationships betxveen media objects. We should therefore investigate replacing our internal movie representation xvith one ....

....edited, analyzed and annotated [18] Davenport et al. proposed using metadata for home movie editing assistance [10] However, they assumed this data would be obtained through manual logging or with a data camera during filming, unlike the automatic techniques used in Silver. The Zodiac system [5] employs a branching edit history to organize and navigate design alternatives. It also uses this abstraction to automatically detect shot and scene boundaries and to support the annotation of moving objects in the video. IMPACT [32] uses automatic cut detection and camera motion classification ....

....object contours. However, before implementing such advanced primitives we first im plement a traditional video authoring tool, which supports basic primitives to create non interactive or passive video content. In this chapter we describe a non linear video editing tool, called Zodiac I [28], which is used to create passive non interactive video streams. In the following chapter we show how addition of advanced primitives in Zodiac H enables active video authoring. Zodiac I takes a set of raw video clips as input. The author arranges segments from these clips on the timeline to ....

....always precede its reference in a contour definition in the meta data stream. When the viewer clicks the middle mouse button, the navigation logic checks if the clicked point lies within any contour in the current video frame. A simple algorithm to check if a point lies in a polygon is given in [28]. If a contour is successfully identified, then its corresponding object definition is retrieved from the object table. The hyperlink script attached to the object is retrieved from the table and executed. Execution of the hyperlink script may result in displaying a piece of text, an image, a ....

....navigation, but they do not support view interpolation for spatial navigation. The most notable one is the HyperSoap [DAK98] project at MIT Media Lab that developed techniques for image segmentation and object tracking in digital video to annotate moving objects. The first version of Zodiac [CHI98] also supports video annotation using object tracking. Zodiac2 uses the same tracking algorithm as its previous version. The HyperCafe system [SAW96] also is able to render video playback an interactive experience by supporting hyper linking to video objects. 3 Object Tracking Algorithm The ....

....Zodiac2 uses the same tracking algorithm as its previous version. The HyperCafe system [SAW96] also is able to render video playback an interactive experience by supporting hyper linking to video objects. 3 Object Tracking Algorithm The object tracking algorithm used in Zodiac2 is same as [CHI98]. Hence we present only a brief outline of the algorithm in this section. An object is defined as the contour on the image plane which encloses the object. A contour typically lies along a region of high color gradient. Zodiac2 uses object contours to not only support annotation in hyper video ....
