Abstract

Multiple streams of data are streamed to a user'"'"'s terminal with images from different cameras. Low resolution thumbnail images tell the user what image streams are available. A focus stream provides high resolution images from a selected camera. A user can switch the focus stream to another stream by clicking on the associated thumbnail. The users can also be provided with a thumbnail of panoramic image. Other data streams sent to the user can contain (a) audio data, (b) interactivity markup data which describes regions of the image which provide interactivity opportunities such as hotspots, (c) presentation markup data which defines how data is presented on the user'"'"'s screen, (d) a telemetry data stream which can be used for various statistical data. One data stream contains a low quality base image for each data stream which can be enhanced to form a high resolution focus image.

Claims

1. ) A system for capturing and displaying images comprising,

a plurality of video cameras viewing an event,

digital storage for storing the outputs from said cameras,

a first edit station with access to said stored video for selecting clips from said video streams,

a second edit station for editing the output of said first edit station,

a web site for storing the edited clips,

a user browser,

a packaging program for creating two video streams one of which is a focus stream and one of which contains a thumbnail of the images from each camera,

a control device at said browser whereby a user can signal to said web site as to which video stream should be the focus stream.

2. ) A system for displaying to a user a selected one of a plurality of video streams, said selected video stream being a focus stream, said system comprising,

a client system which can display said selected video stream, and a composite video containing a thumbnail image of each of said plurality of video streams,

a server which receives a plurality of video streams, and said composite video stream, and which provides a selected one of said video streams and said composite video stream to said client system, and

an input device connected to said client system whereby a user can select one of said thumbnails thereby sending a signal to said server indicating which of said plurality of video streams should be sent to said client system.

3. ) The system recited in claim 2 wherein said server also sends a presentation markup stream to said client machine to control the presentation of images by said client machine.

4. ) The system recited in claim 2 wherein said server also sends an audio stream to said client machine.

5. ) The system recited in claim 2 wherein said server also sends an interactivity mark up stream to said client system to describe regions of the presentation that provide additional user interaction with said system.

6. ) The system recited in claim 2 wherein said server also sends a stream of telemetry data to said client machine.

7. ) The system recited in claim 2 wherein said server also sends an audio stream, a presentation mark up stream, and an interactive markup stream to said client machine.

15. ) The system recited in claim 2 wherein said server and said client are located on one physical computer system.

18. ) The system recited in claim 2 wherein both of said composite images and said high resolution images are contained in the same data stream.

8. ) A method of streaming selected data from a plurality of cameras to a user who is viewing a display on a client machine comprising the steps of:

streaming to said client machine a focus stream containing the images from a particular one of said cameras and a second video stream, each image in which contains a thumbnail of the images from each of said cameras, and

responding when a user selects a thumbnail of the images from a selected camera by making said focus stream the images from said selected camera.

9. ) The method recited in claim 8 wherein a presentation mark up stream is sent to said client machine to indicate to control the display of images on said client machine.

10. ) The method recited in claim 8 wherein an audio stream is also sent to said client machine.

11. ) The method recited in claim 8 wherein an interactivity mark up stream is sent to said client system to describe regions of the presentation that provide additional user interaction with said system.

12. ) The method recited in claim 8 wherein a stream of telemetry data is also sent to said client machine

13. ) A system for displaying video images comprising,

a server which has available a plurality of data streams,

a client,

first means for streaming a first video stream from said server to said client and for simultaneously streaming a second video stream from said server to said client,

said second stream consisting of composite images each of which includes a plurality of low resolution images,

means at said client for receiving said streams and for displaying to a user a high resolution image and a plurality of thumbnails which indicate other streams which are available at said server,

means for allowing said user to indicate which of the streams indicated by said thumbnails, said user would like to form said focus stream.

14. ) The system recited in claim 13 wherein said server and said client are located on one physical computer system.

16. ) The system recited in claim 13 wherein said first stream contains base data which can form low resolution thumbnail images and said second stream contains enhancement data which can be added to a low resolution image to form an enhanced image.

17. ) The system recited in claim 13 wherein one of said low resolution images is an panoramic image and wherein said high resolution image can be a view window from said panorama.

19. ) The system recited in claim 13 wherein a background image is steamed to said client and said high resolution image and said thumbnail images are superimposed over said background image.

20. ) The system recited in claim 13 wherein said high resolution images presented to said user include hot spots which can be used to activate commands.
