US Patent 7912340 Data processing apparatus

A high speed data processing apparatus which is able to produce smooth reproduced pictures without lowering the quality of the reproduced picture. When the high speed reproduction is selected by a user, a system controller controls a media controller to cause a reproducing driver to read out a plural number of stamp video data from an optical disc to write the data in an associated memory space of the memory on the frame basis. The data processing apparatus reads out stamp video data written on the frame basis in a memory space of the memory portion-wise to display the plural number of frames of the picture information simultaneously on one picture frame in each output frame.
