Abstract
A technique that can enhance convenience on each of both sides that distribute and use content under the conditions where use limitations intended to protect the copyright of content have diversified. According to this technique, a right gateway 100 is provided, that converts the condition of use in the right information of content subject to transmission from repository 20 at the transmitting end to repository 30 at the transmission destination in accordance with the right management capacity (capacity information 200) of content in repository 30 at the transmission destination. With right gateway 100 performing processing, the range of equipment and recording mediums capable of use of content expands, thereby promoting the use of content.
