Abstract: A cache control unit of a video data playback control apparatus sets priority video data in order to efficiently use a storage area of a cache memory. The priority video data includes video data which includes a greater number of portions of video data than that of data displayed in a display unit, which includes a smaller number of portions of video data than a maximum number that can be held in the cache memory, and which has a high possibility of being output from the cache memory to the display unit. Also, the cache control unit preferentially reads the priority video data from a recording medium and stores it in the cache memory.
