Abstract

A system for web-based video browsing includes a web server and a web client. The web server and the web client cooperatively provide a set of video browsing functions. The video browsing functions enable a user of the web client to browse a source video and select a video frame from the source video. The distribution of the video browsing functions between the web server and the web client may be adapted to a communication speed between the web server and the web client.

Claims

1. A system for web-based video browsing, comprising a web server and a web client that cooperatively provide a set of video browsing functions that enable a user of the web client to browse a source video and select a video frame from the source video.

2. The system of claim 1, wherein the video browsing functions include a video browser on the web client that enables the user to browse the source video and extract the video frame from the source video and that uploads the video frame to the web server.

3. The system of claim 1, wherein the video browsing functions include a video browser on the web client that enables the user to browse the source video and extract the video frame from the source video and that uploads an identifier for the video frame to the web server.

4. The system of claim 1, wherein the video browsing functions include a compressor and a frame extractor on the web server and a video browser on the web client such that the web client downloads a down-sample of the source video from the compressor and the video browser enables the user to extract a down-sample of the video frame from the down-sample and then uploads an identifier for the video frame to the web server.

5. The system of claim 1, wherein the video browsing functions include a video browser on the web server that generates a set of web pages that enable the user to browse the source video and select the video frame from the source video.

6. The system of claim 1, wherein the video browsing functions include a frame enhancer on the web server that enhances the video frame once selected.

7. The system of claim 1, wherein the video browsing functions include a frame enhancer on the web client that enhances the video frame once selected.

8. The system of claim 1, wherein the video browsing functions include a video browser that extracts a set of key frames from the source video such that the user selects the video frame from among the key frames.

9. The system of claim 1, wherein the video browsing functions include a video browser that extracts a set of key frames from the source video such that the user selects the video frame from among the key frames and one or more sections of the source video that are bounded by the key frames.

10. The system of claim 1, wherein the video browsing functions enable the user to select the video frame for printing.

11. A method for web-based video browsing, comprising distributing a set of video browsing functions among a web server and a web client in response to a characteristic of communication between the web service and the web client such that the video browsing functions enable a user of the web client to browse a source video and select a video frame from the source video.

12. The method of claim 11, wherein distributing comprises providing a video browser on the web client that enables the user to browse the source video and extract the video frame from the source video and that uploads the video frame to the web server.

13. The method of claim 11, wherein distributing comprises providing a video browser on the web client that enables the user to browse the source video and extract the video frame from the source video and that uploads an identifier for the video frame to the web server.

14. The method of claim 11, wherein distributing comprises providing a compressor and a frame extractor on the web server and a video browser on the web client such that the web client downloads a down-sample of the source video from the compressor and the video browser enables the user to extract a down-sample of the video frame from the down-sample and then uploads an identifier for the video frame to the web server.

15. The method of claim 11, wherein distributing comprises providing a video browser on the web server that generates a set of web pages that enable the user to browse the source video and select the video frame from the source video.

16. The method of claim 11, wherein distributing comprises providing a frame enhancer on the web server that enhances the video frame once selected.

17. The method of claim 11, wherein distributing comprises providing a frame enhancer on the web client that enhances the video frame once selected.

18. The method of claim 11, wherein distributing comprises providing a video browser that extracts a set of key frames from the source video such that the user selects the video frame from among the key frames.

19. The method of claim 11, wherein distributing comprises providing a video browser that extracts a set of key frames from the source video such that the user selects the video frame from among the key frames and one or more sections of the source video that are bounded by the key frames.

20. The method of claim 11, wherein distributing comprises providing a video browsing function that enables the user to select the video frame for printing.
