Abstract

A system and method are provided for supporting video browsing over a communication network such as the Internet/World Wide Web. A graphical user interface is provided through a client software tool such as a Web browser. A client/user selects a video data object stored at a remote server. A set of points within the object are displayed at the client'"'"'s graphical user interface display, as representations, preferably thumbnail images, of the points within the object. The user selects an interval defined by the representations, preferably the interval between two temporally adjacent representations. Responsive to this selection, a new set of points, falling within the selected interval, are chosen, and representations of those points are generated and displayed. By doing so repeatedly, the user can easily browse through the video data object, and quickly and easily zero in on a desired portion of the video data object.

Claims

1. A system for facilitating user examination and browsing of video data object information pertaining to a stored video data object (Object), the Object including a beginning point, an end point, and points therebetween, the system comprising:

a display unit;

an interface for coupling the display unit with a network communication medium, the medium being coupled to a video repository having video data objects, including the Object, stored therein;

means for sending, through the interface and over the medium, a request to view the Object;

means, responsive to receipt of a response to the request to view, for displaying a sequence of representations, each representation corresponding with one of the points in the Object;

means for selecting an interval in terms of a first one of the points; and

means, operable responsive to operation of the means for selecting an interval, for providing a subsequence of representations, each representation of the subsequence corresponding with a respective point in the Object, each of the respective points falling within the selected interval.

2. A system as recited in claim 1, wherein:

the network communication medium includes the Internet;

the interface includes an Internet interface; and

the video repository includes a server on the Internet.

3. A system as recited in claim 1, wherein the beginning point, the end point, and the points are temporal points within the Object.

4. A system as recited in claim 1, wherein the means for displaying includes means for displaying still images representative of content of the Object at respective ones of the points in the Object.

5. A system as recited in claim 4, wherein the means for displaying includes:

means for generating thumbnail images based on content of the Object at respective ones of the points in the Object; and

means for displaying the thumbnail images.

6. A system as recited in claim 1, wherein the means for displaying includes:

means for displaying a representation of the Object in its entirety; and

means for displaying a representation of a portion of the Object covered by the displayed representations of points in the Object.

7. A system as recited in claim 6, wherein, in the means for displaying a representation:

the means for displaying the representation in its entirety includes a slider bar; and

the means for displaying a representation of a portion of the Object covered by the displayed representations of points in the Object includes a marker on the slider bar.

8. A system as recited in claim 7, wherein:

the means for selecting an interval includes means for moving the marker along the slider bar from a first position thereon to a second position thereon; and

the means for displaying the sequence of representations includes means, responsive to movement of the marker along the slider, for displaying representations of points within the Object corresponding with the second position of the marker, in place of previously displayed representations of points within the Object corresponding with the first position of the marker.

9. A system as recited in claim 1, wherein the means for selecting an interval includes means for selecting one of the representations of still images which forms a boundary of the interval to be selected.

10. A system as recited in claim 9, wherein the means for selecting an interval further includes means for selecting one of the representations of still images which forms a first boundary of the interval to be selected, a next one of the representations forming a second boundary of the interval.

11. A method for facilitating user examination and browsing of video data object information pertaining to a stored video data object (Object), the Object including a beginning point, an end point, and points therebetween, the method comprising the steps of:

providing, to a user interface, a sequence of representations, each representation corresponding with one of the points in the Object;

wherein the step of providing includes communicating, through a network communication medium, with a video repository having video data objects, including the Object, stored therein;

a user utilizing a user interface to select an interval of the Object in terms of a first one of the points; and

responsive to user selection of such an interval, providing a subsequence of representations, each representation of the subsequence corresponding with a respective point in the Object, each of the respective points falling within the selected interval.

12. A method as recited in claim 11, wherein:

the network communication medium includes the Internet; and

the video repository includes a server on the Internet.

13. A method as recited in claim 11, wherein the beginning, the end, and the points are temporal points within the Object.

14. A method as recited in claim 11, wherein the step of providing a sequence of representations includes displaying still images representative of content of the Object at respective ones of the points in the Object.

15. A method as recited in claim 11, wherein the step of providing a sequence of representations includes:

generating thumbnail images based on content of the Object at respective ones of the points in the Object; and

providing thumbnail images representing still frames of the video object at the respective points therein.

16. A method as recited in claim 11, wherein the step of providing a user interface includes:

displaying a representation of the Object in its entirety; and

displaying a representation of a portion of the Object covered by the displayed representations of points in the Object.

17. A method as recited in claim 16, wherein:

the step of displaying the representation in its entirety includes displaying a slider bar; and

the step of displaying a representation of a portion of the Object covered by the displayed representations of points in the Object includes displaying a marker on the slider bar.

18. A method as recited in claim 17, wherein:

the step of selecting an interval includes moving the marker along the slider bar from a first position thereon to a second position thereon; and

the step of displaying the sequence of representations includes the step, responsive to movement of the marker along the slider, of displaying representations of points within the Object corresponding with the second position of the marker, in place of previously displayed representations of points within the Object corresponding with the first position of the marker.

19. A method as recited in claim 11, wherein the step of selecting an interval includes selecting one of the representations of still images which forms a boundary of the interval to be selected.

20. A method as recited in claim 19, wherein the step of selecting an interval further includes selecting one of the representations of still images which forms a first boundary of the interval to be selected, a next one of the representations forming a second boundary of the interval.
