    摘要: A method and apparatus for reproducing a video using a watermark inserting function. The method of inserting a watermark into a video being reproduced, using an on-screen-display (OSD) data mixer included in a video reproduction apparatus, includes determining a watermark pattern indicating information on reproduction of the original video. The watermark pattern is converted into watermark data capable of being recognized by an OSD data mixer and synthesized with the video being reproduced, using the OSD data mixer.

    摘要: Provided is a method of transmitting content keys to nodes arranged in a hierarchical structure which includes a plurality of node groups each including a predetermined number of the nodes. In this method, revoke information that includes identifiers of revoked node groups in the hierarchical structure, the total number of independent revoked nodes, and identifiers of the independent revoked nodes is generated. The revoked node groups are node groups consisting of only revoked nodes, and the independent revoked nodes are revoked nodes not belonging to any of the revoked node groups. Then, encrypted content keys are obtained by encrypting content keys using broadcast encryption, by using an encryption key set that has a form that cannot be generated using a decryption key set that the revoked nodes possess, and a set of encrypted content keys is generated. Thereafter, the revoke information and the set of the encrypted content keys are transmitted to all of the nodes arranged in the hierarchical structure.
