<p>When the use of the "sound of a first musical composition" in combined content designated to be uploaded is limited by "copyright," a playback musical composition data generating unit (750) generates musical composition data for playback based on second musical composition data which has been synchronized with the beat for the sound of the first musical composition on the basis of first beat information for the sound of a first musical composition and second beat information for the sound of the second musical composition, which is not limited by "copyright." Furthermore, a playback combined content generating unit (760) generates combined content for playback that includes image data and musical composition data for playback generated by the playback musical composition data generating unit (750) in the combined content. Furthermore, an upload unit (740) uploads the combined content for playback to a content server (960). Therefore, even if the other musical composition sound is interchanged for the original musical composition sound, combined content in which the musical composition sound is synchronized with the progress of the image can be created.</p> |
