  • Patent number: 8315725
    Abstract: Appropriate content is determined from among multiple content items, and is reproduced. Content reproduction terminal devices having the content items recorded therein are connected with a content reproduction controlling apparatus. An acquiring unit acquires content information from each content reproduction terminal device, information indicative of the subject matter of the content items. A determining unit determines the content items to be reproduced, i.e., reproduction content based on the acquired content information. An extracting unit extracts the reproduction content from the content reproduction terminal device that has the reproduction content recorded therein. A reproducing unit reproduces and outputs the extracted reproduction content.
