To regenerate digital image data in a right state.
On digital image data, correction information about an aspect ration correction such as a letterbox mode and a squeeze mode is multiplexed as PSM information. The PSM information is detected from bitstreams by a PSM detector 40 and outputted to a control circuit 6. In the control circuit 6, a signal for controlling a horizontal/vertical filter in a display 18 is generated by a signal generator 51 in response to the input PSM information and modulated into a vertical blanking zone by a D/A converter 17, so that an attribute showing the letterbox or squeeze mode is transmitted to the display 18 to operate a corresponding filter in the display 18, and hence an image is displayed in the right state.
