A content management method for managing copying of content (201, 702, 1101, 1601, 1901) by copy control section from a source (1811, 1821) to a destination (1813, 1823), the method comprising: copying the content (201, 702, 1101, 1601, 1901) from the source (1811, 1821) to a bridge apparatus (1812, 1822) by the copy control section, if allowed copy count control information, which is included in additional information associated with the content retained in a data storage section at the source (1811, 1821), indicates that the content is allowed to be copied, wherein the additional information further includes initially allowed move count control information, and currently allowed move count control information, wherein the allowed copy count control information indicates how many copies are allowed to be created out of the associated content, the initially allowed move count control information, which is set at the time of content distribution and whose value stays constant, indicates how many moves of the associated content are allowed initially, the currently allowed move count control information indicates how many moves of the associated content are allowed at this moment, and characterized by decreasing a value of the currently allowed move count control information in a case where the associated content is moved from the source (1811, 1821) to the bridge apparatus (1812, 1822), not decreasing the value of the currently allowed move count control information in a case where the associated content is moved from the bridge apparatus (1812, 1822) to the destination (1813, 1823), generating, at the bridge apparatus (1812, 1822), additional information of the copied content; and setting a value of the currently allowed move count control information included in the additional information associated with the copied content at the bridge apparatus (1812, 1822) by not decreasing the value of the currently allowed move count control information included in the additional information associated with the content at the source (1811, 1821); and moving the content from the bridge apparatus (1812, 1822) to the destination (1813, 1823) according to the currently allowed move count control information. copying the content (201, 702, 1101, 1601, 1901) from the source (1811, 1821) to a bridge apparatus (1812, 1822) by the copy control section, if allowed copy count control information, which is included in additional information associated with the content retained in a data storage section at the source (1811, 1821), indicates that the content is allowed to be copied, wherein the additional information further includes initially allowed move count control information, and currently allowed move count control information, wherein the allowed copy count control information indicates how many copies are allowed to be created out of the associated content, the initially allowed move count control information, which is set at the time of content distribution and whose value stays constant, indicates how many moves of the associated content are allowed initially, the currently allowed move count control information indicates how many moves of the associated content are allowed at this moment, and characterized by decreasing a value of the currently allowed move count control information in a case where the associated content is moved from the source (1811, 1821) to the bridge apparatus (1812, 1822), not decreasing the value of the currently allowed move count control information in a case where the associated content is moved from the bridge apparatus (1812, 1822) to the destination (1813, 1823), generating, at the bridge apparatus (1812, 1822), additional information of the copied content; and setting a value of the currently allowed move count control information included in the additional information associated with the copied content at the bridge apparatus (1812, 1822) by not decreasing the value of the currently allowed move count control information included in the additional information associated with the content at the source (1811, 1821); and moving the content from the bridge apparatus (1812, 1822) to the destination (1813, 1823) according to the currently allowed move count control information.
