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.
Claims21
A method for encoding stereoscopic video, comprising:
- receiving first eye images and second eye images from one or more input video signals;
- calculating deltas from a difference between the first eye images and the second eye images, wherein the deltas are calculated by subtracting the first eye images from the second eye images;
- determining whether two-dimensional digital video or stereoscopic digital video is to be encoded;
- when it is determined that stereoscopic digital video is to be encoded
- storing bit flags in a header of a video stream comprising a first eye image, the header, and a data structure stored in the video stream with the first eye image, the bit flags signifying the presence of a difference stored in the data structure, the difference calculated by determining a difference between the first eye image and a second eye image, and
- encoding an MPEG-compatible stereoscopic digital video stream comprising the first eye image, the header, and the data structure;
- and
- when it is determined that two-dimensional digital video is to be encoded, encoding an MPEG-compatible two-dimensional digital video stream comprising a first eye image and a header, without storing bit flags in the header signifying the presence of a difference in a data structure of the video stream.

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 deltas, wherein the deltas are calculated by subtracting the first eye images from the second eye images to determine a difference between the first eye images and the second eye images;
- and
- an encoder configured to:
- determine whether two-dimensional digital video or stereoscopic digital video is to be encoded,
- when it is determined that stereoscopic digital video is to be encoded,
- store bit flags in a header of a video stream comprising a first eye image, the header, and a data structure stored in the video stream with the first eye image, the bit flags signifying the presence of a difference stored in the data structure, the difference calculated by determining a difference between the first eye image and a second eye image, and
- encode an MPEG-compatible stereoscopic digital video stream comprising the first eye image, the header, and the data structure, and
- when it is determined that two-dimensional digital video is to be encoded, encode an MPEG-compatible two-dimensional digital video stream comprising a first eye image and a header, without storing bit flags in the header signifying the presence of a difference in a data structure of the video stream.
