An attribute-information-area extracting unit extracts an attribute information area in which attribute information is displayed when the attribute information area does not change between certain frames of adjacent scenes obtained by dividing a video content by a scene dividing unit. A character-areas extracting unit extracts character areas in which video attribute information in individual characters that is metadata of the video content of the attribute information area are present, and a character-area-meaning assigning unit assigns meanings to the character areas. A character-area reading unit reads the video attribute information, from the character areas to which meanings are assigned, thereby outputting the video attribute information.
