Abstract

A video karaoke system comprises a first video source and a second video source, providing input to a mixing unit. The mixing unit provides a composite output that includes at least a portion of the video data from the first video source and a portion of video data from the second video source. The output of the mixing unit is configured to display on a display unit. The present invention also provides a method of mixing video data from plurality of video sources providing a combined output. The method comprises providing a plurality of video sources, and a region selecting unit selecting regions of interest from the plurality of video sources. The selected regions of interest from the plurality of video sources are then mixed to provide a combined output video image.

Claims

1. A video karaoke system, comprising:

a first video source that provides a first video data;

a second video source that provides a second video data;

a mixing unit receiving the first video data from the first video source and the second video data from the second video source;

the mixing unit providing a combined output comprising at least a portion of the first video data and the second video data.

2. The video karaoke system according to claim 1 further comprising a display unit for displaying the output of the mixing unit.

3. The video karaoke system as recited in claim 1, wherein the mixing unit mixes the input from the first video source and the second video source in real time.

4. The video karaoke system as recited in claim 2, further comprising a region selecting unit for selecting at least one region of interest in at least one of the first video data and the second video data such that the at least one region of interest can be employed to create the combined output.

5. The video karaoke system as recited in claim 4, wherein the mixing unit further comprises an image tracking unit for tracking the at least one region of interest that is a dynamic region of interest from one of the first and second video sources.

6. The video karaoke system as recited in claim 5 further comprising:

the first video data comprising an associated first shading;

the second video data comprising an associated second shading;

the mixing unit further comprising a shading control for selectively adjusting at least one of the first shading and the second shading, such that the shading of the combined output is consistent.

7. The video karaoke system as recited in claim 6, wherein the mixing unit further comprises a contrast/border adjusting unit for adjusting a contrast and a border between selected portions of the first video data and the second video data that is combined to generate the combined output.

8. The video karaoke system as recited in claim 7, further comprising a feedback control unit for adjusting the output of the mixing unit based upon the combined output.

9. The video karaoke system as recited in claim 2, wherein at least one of the first video data and the second video data comprises a predefined video stream.

10. The video karaoke system as recited in claim 2, wherein at least one of the first video data and the second video data comprise a live video feed from an image capture device.

11. The video karaoke system as recited in claim 2, wherein one of the first and second video sources comprises a video game data, and wherein the other of the first and second video sources comprises a live data from a video feed.

12. The video karaoke system recited in claim 2, wherein the first video data comprises a live video feed from a remote location and wherein the second video data comprises video data from a local video source.

13. The video karaoke system as recited in claim 2 wherein the first video data comprises a video of dynamic activity captured locally from a local video camera in close proximity with a viewer and the second video data comprises a video game data being played by the viewer.

14. The video karaoke system as recited in claim 13 wherein said first video data comprises graphics.

15. The video karaoke system recited in claim 2 wherein said first video data comprises textual data.

16. The video karaoke system as recited in claim 2, wherein the first data is a computer generated action sequence, the second video source is a video camera tracking and capturing a viewer'"'"'s movements as the viewer responds to the combined output displayed on the display unit, the second video data comprising a live video data from the video camera.

17. The video karaoke system as recited in claim 2, further comprising a display receiving input from the mixing unit, and wherein said display is configured in proximity to one of the first and second video sources, and wherein video data from the one of the first and second video sources is influenced by the combined output shown on the display unit.

18. The video karaoke system as recited in claim 2, wherein the mixing unit selects at least one first region of interest from a plurality of regions of interest from the first video data and at least one second region of interest from a plurality of regions of interest from the second video data in order to generate the combined output.

19. The video karaoke system as recited in claim 2, further comprising a selecting unit for selecting a region of interest of one of the first video data and the second video data, the selecting unit capable of being managed and manipulated by an input device that is one of a keyboard, a mouse, a remote pointing device, a tablet, and a touch screen.

24. The video karaoke system of claim 1, further comprising additional video sources providing additional video data which is input to the mixing unit.

20. A method for generating video karaoke, the method comprising:

receiving a first video data from a first video source;

obtaining a second video data from a second video source;

selecting a selected region of interest from one of the first video data and the second video data;

mixing the selected region of interest with the other of the one of the first video data and the second video data, thereby creating a combined video output in real time.

21. The method as recited in claim 20 wherein the step of receiving the first video data comprises capturing a dynamic video data from an image capture device;

wherein said step of obtaining the second video data comprises retrieving prerecorded video data from the second video source;

wherein said selecting comprises identifying a portion of the first video data; and

wherein mixing comprises combining the selected portion of the first video data with the second video data.

22. The method as recited in claim 21 wherein the dynamic video data that is captured by the image capture device comprises a video data tracking the movements of a viewer viewing the combined video output in real time on a display unit, that is in close visual proximity to the viewer and the image capture device.

23. The method as recited in claim 20 further comprising:

adjusting a shading of the selected video data in the selected region of interest such that the combined output is an enhanced superimposition of the selected video data and the other of the one of the first video data and the second video data.
