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.

Abstract: A system and method of determining whether an object captured in a series of images is a three dimensional object or an image of an object by comparing image data of the object captured in the images at various angles relative to the object, to image data of one or more reference images of an actual object. The image data derived from the captured images may vary with the different angles at which such images were captured and such variances may be compared to the reference images, whereas image data of an image of an object will not comparably vary.
