摘要： The present invention provides an access control method of controlling acceptance or rejection of access to content from metadata. The access control method according to the present invention includes a step of producing metadata 3A for content 6A and embedding a digital signature 4A of a producer who has produced the metadata as producer information in the produced metadata 3A, a step of embedding an identifier 5A indicating which metadata are accessible to the content in license information required to play back the content 6A, and an access propriety control step of comparing the digital signature 4A with the identifier 5A to control propriety of access to the content 6A from the produced metadata 3A.

摘要： A method of distributing contents in a system including a distribution station for distributing contents, a relay station for relaying the contents, a management apparatus for receiving the contents distributed from the distribution station or the relay station and managing the contents, and a plurality of terminal apparatuses for receiving the contents distributed from the management apparatus, the method comprising the steps of: attaching metadata to the contents distributed from the distribution station; and adding location information of the relay station, the management apparatus or each of the terminal apparatuses to the metadata of the contents when the contents are stored in the relay station, the management apparatus or the terminal apparatus. The contents can be displayed on the user side concentratedly regardless of locations of the contents so that the contents can be acquired or played back without user's consciousness of locations of the large number of contents.
