A sub picture buffer (7) temporarily stores top field sub picture data and bottom field sub picture data which have been subjected to the run length compression. A sub picture magnifying/demagnifying unit (8) subjects the sub picture data to a display magnification process accompanied by the interpolation of line data. A sub picture output buffer (9) temporarily stores the sub picture data which has been subjected to the display magnification process. A video buffer (5) temporarily stores video packet data. A video decoding unit (10) decodes the video packet data and the sub picture data which has been subjected to the display magnification process, and combines the decoded video packet data with the decoded sub picture data and outputs the combined data thus obtained.
