A content reproduction screen displays a plurality of content items. A video reproduction processing section reproduces substantially simultaneously videos of a plurality of content items on a screen. An audio reproduction processing section reproduces substantially simultaneously audio signals of a plurality of content items. During reproduction of a plurality of content items, a comparison is made between a current reproduction position of the audio signal in an audio reproduction processing section and a current reproduction position of each video in the video reproduction processing section, and, if a discrepancy between the compared current reproduction positions is equal to or greater than a threshold value, the current reproduction position of the video is corrected on the basis of the current reproduction position of the audio signal. In this way, the current reproduction position of each video is synchronized with the reproduction position of the audio signal.
