Abstract: A reproduction list is produced, in which audio data and still image data coexist and a reproduction order thereof is specified. Items of the audio data and the still image data are grouped so as to be associated with each other based on the point of transition between the audio data and the still image data in the reproduction list, and the audio data and the still image data in the same group are reproduced simultaneously.
