<p>The invention relates to a method and system for digital decoding MPEG2-compatible 3D stereoscopic video images with their own codification algorithm. In order to obtain 3D images in a digital video stream, changes have been made to the current MPEG2 decoders by making hardware and software changes in different parts of the decoding process, namely the structures and the video sequence of the video stream are modified in order to include the necessary flags that identify the type of TDVision?? technology image at bit level. Modifications are made in the decoding processes, for instance, while decoding information via software and hardware, in which a double output buffer is activated, a parallel and differences decoding selector is activated, the decompression process is carried out and the image is displayed in the corresponding output buffer; the decoder is programmed via the software in order to receive and decode simultaneously two independent program streams with a TDVision?? stereoscopic identifier.</p> |
