Abstract
An apparatus and/or system implements a method for storing and reproducing contents received through broadcast signals, where the method of managing content includes reconstructing a broadcast signal received from a broadcasting company, transmitting a content ID and predetermined authentication information to the broadcasting company, the content ID used to discriminate content contained in the broadcast signal, receiving content management information including a content key corresponding to the content ID from the broadcasting company, encrypting the content using the content key, and storing the encrypted content in a content storage apparatus.
Claims35
A method of managing content comprising:
- reconstructing, by a content management apparatus, a content received from a content provider;
- transmitting, from the content management apparatus after receiving the content, a content ID and authentication information to the content provider, the content ID used to identify the content received from the content provider;
- receiving, at the content management apparatus, content management information corresponding to the content ID from the content provider;
- encrypting, by the content management apparatus, the reconstructed content based on the received content management information;
- and
- storing the encrypted content in a content storage apparatus,
- wherein the authentication information includes key information which is used to encrypt the content management information.
An apparatus for managing content comprising:
- a reconstruction module which reconstructs a content received from a content provider;
- a network interface module which transmits a content ID and authentication information to the content provider after receiving the content and receives content management information corresponding to the content ID from the content provider, the content ID being used to identify the content received from the content provider;
- an encryption/decryption module which encrypts the reconstructed content based on the received content management information;
- and
- a device interface module which stores the encrypted content in a content storage apparatus,
- wherein the authentication information includes key information which is used to encrypt the content management information.
A method managing content comprising:
- transmitting, from a managing apparatus, a content ID to a content source from which content corresponding to the content ID has been received;
- receiving at the managing apparatus content management information corresponding to the content ID from the content source and which restricts reproduction of the received content;
- and storing by the managing apparatus the content management information such that, prior to reproduction of the stored content, the managing apparatus can recall the stored content management information to restrict reproduction of the stored contents, wherein:
- the receiving at the managing apparatus the content management information comprises receiving encryption information related to the content ID, and the controlling the content to be stored comprises encrypting by the managing apparatus the content according to the received encryption information, and controlling the encrypted content to be stored on the medium.
A method of remotely managing stored content comprising:
- sending content from a content source to be reproduced at a receiver;
- receiving at the content source a content ID corresponding to the sent content and authentication information;
- and sending from the content source to the receiver content management information corresponding to the received content ID and which allows storage of the sent content on a medium and restricts subsequent reproduction of the stored content by the receiver, wherein the authentication information includes key information which is used to encrypt the content management information, wherein the sending the content management information further comprises sending encryption information related to the content ID used by the receiver to encrypt and store the sent contents on the medium.
