A pair of video streams is prepared for stereoscopic display. A pair of frames is rectified. Each of the pair of frames is from a respective stream of the pair of video streams. A reduced video stream is generated by removing from one of the pair of video streams a set of correlative data that is present in or can be predicted from the other of the pair of video streams. The reduced video stream and the other of the pair of video streams are compressed for use in stereoscopic display of the reduced video stream and the other of the pair of video streams.
