Abstract: A comment delivery server associates comment contents in which an elapsed contents playback time has been set as a comment attachment time with contents identification information, and stores these as comment information. The comment delivery server reads from a comment information storage section comment information which corresponds to contents identification information received by a contents identification information receiving section, and delivers it to a terminal device. The terminal device transmits identification information for contents targeted for playback to the comment delivery server, receives comment information transmitted from the comment delivery server, and stores the received comment information.
