An OSD device is provided which allows a reduction in the capacity of a memory for storing OSD data and also allows the efficient use of a transfer frequency band in the transfer of the OSD data. A management information data set MD includes, for the display position of each of OSD data sets OD to be superimposed on sensed image data sets SD, display position information sets HDISP and VDISP on the OSD data set OD and a storage location information set WORD on the OSD data set OD. The on-screen display device comprises an OSD data storage region ( 32 ) for storing the OSD data sets OD, senses the management information data set MD having HDISP and VDISP which match the display position of each of the sensed image data sets SD, and retrieves the OSD data sets stored in WORD included in the management information data set MD from the OSD data storage region ( 32 ).
