Abstract:
A device for converting a frame rate in a moving picture decoder which device decodes encoded moving picture data whose out frame rate has been set to 24 Hz and provides pictures at an output frame rate of 30 Hz or 60 Hz based on the decoded moving picture data, said device comprising:a header information extracting section for extracting repeat-first-field information, progressive-sequence information and progressive-frame information contained in an in input stream corresponding to each picture as header information from said stream; a storage section for storming said header information extracted by said header information extracting section; wherein said control section reads said header information stored in said storage section in accordance with the order in which said pictures are displayed, determines whether each picture is for the progressive scanning fling based on said progressive-sequence information when said repeat-first-field information contained in the relevant header information does not indicate a re-display of the relevant picture, and carries out a control to re-display one field of a picture once every two frames when the result of said determination indicates the progressive scanning.
