Abstract

A method and system for simultaneously displaying multiple video angles of multimedia content onto a single display device includes: reading a video source signal from the multimedia content; demultiplexing the video source signal into a plurality of video angles; decoding at least two of the plurality of video angles according to an encoding scheme of the multimedia content; rendering at least two of the decoded video angles; composing at least two of the rendered video angles into a final video signal; and outputting the final video signal onto the single display device.

Claims

1. A method for simultaneously displaying multiple video angles of multimedia content onto a single display device, the method comprising:

reading a video source signal from the multimedia content;

demultiplexing the video source signal into a plurality of video angles;

decoding at least two of the demultiplexed video angles according to an encoding scheme of the multimedia content;

rendering at least two of the decoded video angles;

composing at least two of the rendered video angles into a final video signal; and

outputting the final video signal onto the single display device.

2. The method of claim 1, wherein the multimedia content comprises a digital versatile disc (DVD), a high-definition DVD (HDDVD), or a blue-ray disc (BD).

3. The method of claim 1, wherein the multimedia content comprises an optical disc.

4. The method of claim 1, wherein the multimedia content comprises a solid state memory device.

5. The method of claim 1, wherein the video source signal comprises a digital TV (DTV) satellite signal or a high-definition digital TV (HDTV) signal.

6. The method of claim 1 further comprising

selecting at least two desired video angles.

7. The method of claim 6 further comprising decoding the selected video angles according to an encoding scheme of the multimedia content.

8. The method of claim 6 further comprising rendering the selected video angles.

9. The method of claim 6 further comprising composing the selected video angles.

10. The method of claim 1, wherein the step of outputting the final video signal onto the single display device comprises displaying the final video signal onto the single display device in a split screen mode.

11. The method of claim 1, wherein the step of outputting the final video signal onto the single display device comprises displaying the final video signal onto the single display device in a picture in picture (PiP) mode.

12. A multimedia playback system comprising:

a navigation unit for reading a video source signal from multimedia content and demultiplexing the video source signal into a plurality of video angles;

at least two decoding units, each of the decoding units for simultaneously decoding one video angle of the plurality of video angles according to an encoding scheme of the multimedia content;

at least two rendering units, each of the rendering unit for simultaneously rendering one of the decoded video angles; and

an angle composer for composing at least two of the rendered video angles into a final video signal and for outputting the final video signal onto a single display unit.

13. The multimedia playback system of claim 12, wherein the multimedia content comprises a digital versatile disc (DVD), an high-definition DVD (HDDVD), or a blue-ray disc (BD).

14. The multimedia playback system of claim 12 wherein the multimedia content comprises an optical disc.

15. The multimedia playback system of claim 12, wherein the multimedia content comprises a solid state memory device.

16. The multimedia playback system of claim 12, wherein the video source signal comprises a digital TV (DTV) satellite signal or a high-definition digital TV (HDTV) signal.

17. The multimedia playback system of claim 12 further comprising a user interface for allowing a viewer of the multimedia content to select at least two video angles of the plurality of video angles for display.

18. The multimedia playback system of claim 17, wherein the decoding units are for simultaneously decoding the selected video angles.

19. The multimedia playback system of claim 17, wherein the rendering units are for simultaneously rendering the selected video angles.

20. The multimedia playback system of claim 17, wherein the angle composer is for composing the selected video angles.
