Abstract
A frame-rate converting device in a moving picture decoder which realizes a smooth display of pictures at a frame rate of 30 Hz or 60 Hz based on stream data whose frame rate of 24 Hz is provided. A control section performs a 3:2 pull-down processing when the output frame rate is 24 Hz and when a re-display of picture is indicated. When a re-display of picture is not indicated, the control section detects that the picture is of a progressive material, and repeats one field every two frames. When the picture is not a progressive material, the control section determines whether the top and the bottom of the picture are of the same time instant and repeats one field every two frames when they are of the same time instant but repeats one frame every four frames when they are not of the same time instant.
