Abstract

Embodiments of the present invention are operable to produce MPEG or like video streams from video data that is accompanied by metadata. This greatly reduces the processing requirements associated with encoding an MPEG or other like standard video stream. This is achieved by decoding formatted video data received from a computer system with a video processor. A frame or series of frames may be produced from the formatted video data by the video processor. In the instance where a series of frames are produced, these may be supplied to a display driver and presented on an operatively coupled display. The image frame or series of image frames may be supplied to a video stream encoder along with the metadata wherein the video stream encoder is operable to apply the metadata to the image or series of images in order to produce a set of instructions that allow subsequent images to be generated from the image or images produced by the video processor. This second video stream can then be distributed within a video display network.

Claims

1. A method operable to produce at least two video streams, comprising:

receiving formatted video data from a computer system, wherein the formatted video data is accompanied by metadata;

decoding the formatted video data with a video processor;

producing with the video processor a first video stream that comprises a series of image frames, wherein the series of image frames are operable to be presented on a display;

supplying the first video stream and metadata, wherein the metadata is synchronized to the first video stream, to a video stream encoder;

producing, with the video stream encoder, a second video stream based on the first video stream and metadata; and

distributing the second video stream within a video display network.

2. The method of claim 1, wherein the formatted video data comprises video data utilizing a first video standard selected from the group consisting of:

High definition Television (HDTV);

OpenGL;

a 3D graphics language variant;

DirectX;

Moving Picture Experts Group (MPEG);

Video Graphics Adapter (VGA);

Super VGA (SVGA); and

Enhanced Graphics adapter (EGA).

3. The method of claim 1, wherein the second video stream utilizes a variant of a Moving Picture Experts Group (MPEG) standard.

4. The method of claim 1, wherein producing, with the video stream encoder, the second video stream based on the first video stream and metadata further comprises:

applying the metadata to a frame within the series of image frames to produce at least one subsequent frame.

5. The method of claim 1, wherein the second video stream is distributed wirelessly to the display network.

6. The method of claim 1, wherein the metadata comprises object information for objects within the formatted video data.

7. A method operable to produce a Moving Picture Experts Group (MPEG) video stream, comprising:

receiving formatted video data from a computer system, wherein the formatted video data is accompanied by metadata;

decoding the formatted video data with a video processor;

producing with the video processor at least one image frame from the formatted video data; and

applying the metadata to the at least one frame to produce the MPEG video stream.

8. The method of claim 7, wherein the formatted video data comprises video data utilizing a first video standard selected from the group consisting of:

Direct3D;

OpenGL;

a 3D graphics language variant;

DirectX;

Moving Picture Experts Group (MPEG);

Video Graphics Adapter (VGA);

Super VGA (SVGA); and

Enhanced Graphics adapter (EGA).

9. The method of claim 7, wherein the MPEG video stream utilizes a variant of the MPEG standard.

10. The method of claim 9, wherein the MPEG video stream is distributed wirelessly to a display network.

11. The method of claim 7, wherein the metadata comprises object information for objects within the formatted video data.

12. A video processing system operable to distribute a Moving Picture Experts Group (MPEG) video stream, comprising:

an interface operable to receive formatted video data from a computer system, wherein the formatted video data is accompanied by metadata;

a video decoder operably coupled to the interface and memory, wherein the video decoder is operable to produce a plurality of image frames from the formatted video data; and

a video stream encoder, operably coupled to the computer system and the video decoder, wherein the video stream encoder is operable to produce the MPEG video stream from the plurality of image frames and the metadata.

13. The video processing system of claim 12, wherein the video decoder is further operable to produce a second video stream comprising a stream of the plurality of image frames.

14. The video processing system of claim 12, further comprising a display driver operable to render the second video stream to a monitor.

15. The video processing system of claim 14, wherein the display driver renders the second video stream by scanning rows and columns.

16. The video processing system of claim 12, wherein a video display network operably couples to the output of the video stream encoder.

17. The video processing system of claim 12, wherein a video display network operably wirelessly couples to the output of the video stream encoder.

18. A video card operable to render a Moving Picture Experts Group (MPEG) video stream, comprising:

an interface operable to receive formatted video data from a computer system, wherein the formatted video data comprises metadata;

a video processor comprising;

a video decoder operably coupled to the interface, wherein the video decoder is operable to produce a plurality of image frames from the formatted video data; and

computer memory operably coupled to the video decoder, wherein the computer memory is operable to store the plurality of image frames; and

a video stream encoder, operably coupled to the computer system and the video processor, wherein the video stream encoder is operable to produce the MPEG video stream from the plurality of image frames and the metadata.

19. The video card of claim 18, wherein the plurality of image frames comprises a second video stream.

20. The video card of claim 18, further comprising a display driver operable to render the second video stream to a monitor.

21. The video card of claim 20, wherein the display driver renders the second video stream by scanning rows and columns.

22. The video card of claim 18, further comprising a display network interface operably coupled to the MPEG encoder, wherein the display network interface delivers the MPEG stream to a display network.

23. The video card of claim 22, wherein the display network interface wirelessly delivers the MPEG stream to the display network.

24. The video card of claim 22, wherein the formatted video data comprises video data utilizing a first video standard selected from the group consisting of:

High definition Television (HDTV);

OpenGL;

a 3D graphics language variant;

DirectX;
