Abstract

In order to obtain three-dimensional images from a digital video stream, certain modifications have been made to the current MPEG2 coders; software and hardware changes in different parts of the coding process are made. In effect, the structures and the video_sequence of the video data stream are modified to include the necessary flags to identify at the bit level the TDVision® technology image type.

Claims

1. A system for encoding stereoscopic digital videos, comprising:

a receiver configured to receive first eye images and second eye images from one or more input video signals;

a processor configured to calculate difference images from at least a difference between the first eye images and the second eye images; and

an encoder configured to output first eye images and the difference images in one or more output video streams, wherein the one or more output video streams comprise a header, the first eye images and the difference images and wherein the header comprises data that indicates to a decoder that difference images are present within the one or more output video streams.

2. The system of claim 1, wherein the system is part of at least one of a cable system, a high definition television system, a satellite television system, an optical disk system, or a digital television system.

3. The system of claim 1, wherein the encoder further performs error correction on the difference images.

4. The system of claim 1, wherein the processor is configured to calculate the difference images as B type image frames, and the B type image frames are calculated from a plurality of first eye images and second eye images.

5. The system of claim 1, wherein the processor is configured to calculate the difference images as P type image frames.

6. The system of claim 1, wherein the encoder is configured to store a predetermined set of bits in the header to indicate that the one or more output video streams comprise difference images.

7. The system of claim 1, wherein the encoder is configured to store the difference images in a data structure specific for the difference images.

8. The system of claim 1, wherein the one or more output video streams comprise a plurality of video streams.

9. The system of claim 1, wherein the one or more output video streams are MPEG compatible video streams.

10. The system of claim 1, wherein the encoder is configured to store the header and first eye images in a first video stream and the difference images in a predetermined data structure.

11. A stereoscopic video encoding system, comprising:

at least one buffer configured to receive first eye images and second eye images from one or more input video signals;

first software for calculating difference images from a difference between the first eye images and the second eye images; and

second software for storing first eye images and the difference images in one or more output video streams, wherein the one or more output video streams comprise a header, the first eye images and the difference images and wherein the header comprises data that indicates to a decoder that difference images are present within the one or more output video streams.

12. The system of claim 11, wherein the at least one buffer is part of a digital signal processor.

13. The system of claim 11, wherein the system is part of at least one of a cable system, a high definition television system, a satellite television system, an optical disk system, or a digital television system.

14. The system of claim 11, further comprising instructions that perform error correction on the difference images.

15. The system of claim 11, wherein the first software and the second software are part of the same software.

16. The system of claim 11, wherein the second software stores a predetermined set of bits in the header to indicate that the one or more output video streams comprise difference images.

17. The system of claim 11, wherein the second software stores the difference images in a data structure specific for the difference images.

18. The system of claim 11, wherein the one or more output video streams are MPEG compatible video streams.

19. The system of claim 18, wherein the first software calculates the difference images as B or P type image frames.

20. The system of claim 11, wherein the second software is configured to store the header and first eye images in a first video stream and the difference images in a predetermined data structure.
