SYSTEM AND METHOD FOR DECODING 3D STEREOSCOPIC DIGITAL VIDEO
First Claim
1. A system for displaying a stereoscopic digital video to a user, comprising:
- a receiver configured to receive one or more video streams, wherein the one or more video streams comprise a header and a first eye image;
a decoder configured to read the header and determine if the one or more video streams also comprise a delta image, wherein the delta image was derived from the difference between the first eye image and a second eye image, and wherein if the header indicates that the delta image is present, constructing a decoded second eye image from the delta image and the first eye image; and
a video output configured to output the stereoscopic digital video from the first eye image and the decoded second eye image.

Abstract
Described herein is a MPEG-2 compatible stereoscopic 3D-video image digital decoding method and system. In order to obtain 3D-images from a digital video stream, modifications are made to the current MPEG2 decoders, by means of software and hardware changes in different parts of the decoding process. Namely, the video_sequence structures of the video data stream are modified via software to include the necessary flags at the bit level of the image type in the TDVision® technology. Modifications are also made in the decoding processes as well as in decoding the information via software and hardware, wherein a double output buffer is activated, a parallel and difference decoding selector is activated, the decompression process is executed, the corresponding output buffer is displayed; and the decoder is programmed via software to simultaneously receive and decode two independent program streams, each with an TDVision® stereoscopic identifier.
