Abstract

A video streaming system that supports an additional layer for lighting effects in video streams transmitted from a broadcast studio such that a video layer with special effects is transmitted separately from the video stream by a transmitter makes it possible to provide for user selectable video lighting effects. A corresponding user box/consumer box capable of using the additional layers of video effects makes it possible to display such lighting effects on the video stream. The consumer box activates at least one effects form the plurality of effects on the input video stream, according to the user'"'"'s selections and preferences. In one embodiment, a mixing unit makes it possible to mix the video streams with the special effects sent in the additional layers and the output of the mixing unit is configured to be displayed on a display unit.

Claims

1. A video broadcasting system, said system comprising:

a video data receiving unit for receiving video data from a video source;

a video stream transmission unit for transmitting the video data as a video stream;

a video effects database for storing and transmitting selected video effects as a layer on the video stream;

wherein the video stream is configured whereby selected video effects are superimposed on the video data.

2. A video broadcasting system as recited in claim 1, wherein said video effects data includes selection data which enables a user to select video effects.

6. A video broadcasting system as recited in claim 1, wherein the transmitting unit transmits a live video feed from an image capture device.

7. The video broadcasting system as recited in claim 1, wherein the transmitting unit transmits a recorded video stream.

8. The video broadcasting system as recited in claim 1, wherein the transmitting unit transmits video data from a video game.

9. The video broadcasting system as recited in claim 1, wherein the transmitting unit transmits a broadcast of a sporting event.

10. A video broadcasting system as recited in claim 1, wherein the video effects transmission unit includes a video effects selection unit for selecting and applying video effects from the video effects data.

11. A video broadcasting system as recited in claim 1, wherein said video data receiving unit includes a video effects selection unit for selecting and applying video effects from the video effects data.

12. A video broadcasting system as recited in claim 1, wherein said video stream transmission unit transmits video data as a first layer and video effect data as a second layer on said video stream.

13. A video broadcasting system as recited in claim 12, wherein said video data comprises data packets having a first identifier, and wherein said video effect data comprises packets having a second identifier.

14. A video broadcasting system as recited in claim 13, wherein some video effect packets are disposed between the video data packets in the video stream.

3. A video effects unit for applying selectable video effects on a video stream, said unit comprising:

a data receiving unit for receiving a video stream containing video data from a video source;

a region selecting unit for selecting a region of interest from the video data;

an effects selection unit for selecting effects from a layer of said video stream, wherein said effects are configured to be applied to the video data;

a superimposing unit for applying selected effects from the effects selection unit to one of the selected region of interest and other regions of the video data.

4. The video effects unit as recited in claim 3, further comprising a display for displaying the video data.

5. The video effects unit as recited in claim 3, further comprising a tracking unit for tracking the selected region of interest.

15. A video broadcasting system, said system comprising:

video data receiving means for receiving video data from a video source;

video stream transmission means for transmitting video data as a video stream from the video source;

video effects storage means for storing and transmitting selected video effects as a layer on the video stream,

wherein the video stream is configured such that selected video effects are superimposed on the video data.

16. A video effects unit for applying selectable video effects on a video stream, said video effects unit comprising:

data receiving means for receiving a video stream containing video data from a video source;

region selecting means for selecting a region of interest from the video data;

effects selection means for selecting effects from a layer of the video stream, wherein said effects are configured to be applied to the video data;

superimposing means for applying selected effects from the effects selection means to one of the selected region of interest and other regions of the video data.

17. The video effects unit as recited in claim 16, further comprising display means for displaying the video data.

18. The video effects unit as recited in claim 16, further comprising tracking means for tracking the selected region of interest.

19. A video transmission system, said system comprising:

a video data interface for receiving video data from a video source;

a video effects database for storing selected video effects, wherein said selected video effects are configured to be applied to the video data;

selection means for selecting and applying selected video effects from the video effects database, and applying the selected video effects to selected regions of interest of the video data;

output means for outputting the video stream comprising the video data and the selected video effects.
