1. A method for processing a video stream of digital images, the method comprising the steps of:

  • receiving the video stream which comprises at least one composite frame (FC), each composite frame containing a pair of stereoscopic digital images (L,R) according to a predetermined frame packing format;

    generating an output video stream which can be reproduced on a visualization apparatus,receiving metadata which determine an area occupied by one of the two images within said composite frame (FC), said metadata indicating either a geometry of the frame packing format or a frame packing type of said composite frame (FC);

    determining the area in the composite frame (FC) which is occupied by said one image of the stereoscopic pair within the composite frame based on said metadata;

    decoding only that part of the composite frame (FC) which contains said one image to be displayed, andgenerating an output frame containing said decoded image.
