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 TM technology image type. Regarding software, the modifications will be made in the following processes: video_sequence header, identification flags modification, data fields modification, and image fields modification. Regarding hardware, an electronic comparison is made between the images of the left and right channels, the difference is processed as a B type image, i.e., an error correction is performed, the results are stored in a temporary buffer with the TDVision TM technology identifier. When the information is coded, a DSP is used to perform the prediction, comparison, quantization, and DCT function application processes in order to form the MPEG2-compatible compressed video stream.
