APPARATUS AND METHODS FOR MULTIPLEXING, RECORDING AND CONTROLLING THE DISPLAY OF IMAGE DATA, AND RECORDING MEDIUM THEREFOR

摘要

Digital image data which has been compressed in accordance with the MPEG system and corrected for aspect ratio is multiplexed with correction da ta provided as PSM data for correcting the aspect ratio of such digital image data in the letterbox mode, squeeze mode or the like. The PSM data is detected from the bit stream by a PSM detector and a control signal is generated in response t o the detected PSM data for controlling filters of a display so that the latter displays an image in the correction state.
