Abstract

A single composite stream of data is streamed to a user'"'"'s terminal and displayed in two separate viewers. This composite stream embeds a series of substreams that are views of the same event, taken from different point of views. A first viewer, the global viewer, displays the entire composite stream of data, thus displays the n substreams the composite stream may contain. The second viewer, the focus viewer, displays only part of the composite stream in order to display the substream currently selected by the user. While the stream is played back, the user may interact with an external application'"'"'s user interface to select which of the n embedded streams he wants to be displayed in the focus viewer, thus creating a cut. The series of cuts created by the user is stored internally for playback management. The user may export the series of cuts he created in an editing file (EDL formatted, for instance, without being restricted to) that can be loaded into a professional editing application. This professional editing application will then be used to create the final version of the clip.

Claims

1. A video editing system comprising:

a plurality of video sources;

a composite video generator receiving said video sources and providing a file of a composite video containing said video sources;

a video streaming server receiving said composite video file and connected to a wide area network for streaming said composite video file for real-time display;

a remote video editor connected to said network and receiving a real-time stream of said composite video file over said network from said video streaming server, said editor having;

a composite display window displaying said composite video from said stream;

a source selection interface for receiving a user selection of a desired one of said video sources during said receiving of said stream;

an edit file generator receiving said user selection to generate an edit control file;

a video editor retrieving, separately in time from said receiving said stream, said plurality of video sources and said edit control file to generate and store an edited video file in accordance with said edit control file.

2. The video editing system as claimed in claim 1, further comprising:

a focus display window displaying a copy of said desired one of said video sources from said composite video.

3. The video editing system as claimed in claim 1, wherein said composite display window is a single window having said video sources arranged in an n by m matrix.

4. The video editing system as claimed in claim 1, wherein said composite display window is adapted to display or portion of said composite video corresponding to a portion of said video sources.

5. The video editing system as claimed in claim 4, wherein said composite display window comprises two or more windows each presenting a portion of said composite video corresponding to a portion of said video sources.

6. The video editing system as claimed in claim 5, wherein said two or more windows are arranged in a row or column and present all of said video sources contained in said composite video.

7. The video editing system as claimed in claim 1, wherein a dimension or resolution of said composite video is larger than a standard resolution for a computer screen, and said composite video is resized or cropped and rearranged to fit on at least one display surface.

8. The video editing system as claimed in claim 7, wherein said dimension or resolution of said composite video is selected as a function of an available bandwidth of a transmission channel over said wide area network, said composite video being scaled appropriately prior to display in said composite display window.

9. The video editing system as claimed in claim 8, wherein said dimension or resolution is doubled when available bandwidth is above a given threshold.

10. A synchronous video viewing system comprising:

a plurality of video sources;

a composite video generator receiving said video sources and providing a file of a composite video containing said video sources;

a video streaming server receiving said composite video file and connected to a wide area network for streaming said composite video file for real-time display; and

a remote video viewer connected to said network and receiving a real-time stream of said composite video file over said network from said video streaming server, said viewer having;

a source selection interface for receiving a user selection of a desired one of said video sources during said receiving of said stream; and

a focus display window displaying a copy of said desired one of said video sources extracted from said composite video.

11. The video editing system as claimed in claim 10, wherein said composite display window is a single window having said video sources arranged in an n by m matrix.

12. The video editing system as claimed in claim 10, wherein said composite display window is adapted to display or portion of said composite video corresponding to a portion of said video sources.

13. The video editing system as claimed in claim 12, wherein said composite display window comprises two or more windows each presenting a portion of said composite video corresponding to a portion of said video sources.

14. The video editing system as claimed in claim 13, wherein said two or more windows are arranged in a row or column and present all of said video sources contained in said composite video.

15. The video editing system as claimed in claim 10, wherein a dimension or resolution of said composite video is larger than a standard resolution for a computer screen, and said composite video is resized or cropped and rearranged to fit on at least one display surface.

16. The video editing system as claimed in claim 15, wherein said dimension or resolution of said composite video is selected as a function of an available bandwidth of a transmission channel over said wide area network, said composite video being scaled appropriately prior to display in said composite display window.

17. The video editing system as claimed in claim 16, wherein said dimension or resolution is doubled when available bandwidth is above a given threshold.
