SYSTEM AND METHOD FOR ENCODING 3D STEREOSCOPIC DIGITAL VIDEO

摘要

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.

1. 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, andencoding 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.
