Content reproducing apparatus includes a synchronization control section that transmits synchronization control signals including information specifying a program to a program executing section which generates bitmap data of an image to be overlaid with content data and stores the bitmap data in a plurality of buffer memories. The synchronization control section also synchronizes reproduction of content data with (i) generation of bitmap data in the program executing section, and (ii) output of stored bitmap data by an output control section on the basis of respective first and second timing information indicative of first and second time points in a time period during which content data is reproduced. A method for reproducing content utilizing the content reproducing apparatus, a non-transitory content recording medium for causing the apparatus to carry out the method, and a non-transitory, computer-readable medium storing a control program for causing the content reproducing apparatus to practice the method also are provided.
