摘要： A streaming system includes an authoring unit (2), a stream server (3) and a client terminal (5). The authoring unit generates a file composed of encrypted contents data and the ancillary information at least containing the packetizing control information for generating an RTP packet, a non-encrypted codec dependent header made up of the information pertinent to encoded contents data, and the encryption information for decrypting the encrypted contents data form packet to packet. The streaming server packetizes the encrypted contents data along with at least the codec dependent header and distributes the resulting data as a stream. The client terminal refers to the codec dependent header of the received packet, re-assembles the packet, and decrypts the encrypted contents data of the re-assembled packet to generate contents data.

摘要： The present invention is directed to a streaming system for encrypting encrypted data such as music and image, etc. to perform stream distribution thereof. Client terminals (30) used in this system structure leaves of the hierarchical tree structure, and hold a key set consisting of a route key, node keys and the own leaf key on a path of this tree structure, whereby SDP file is transmitted from a stream server (20). In the SDP file, there is stored encrypted information consisting of EKB including data encrypted by selection key that only specific client terminal holds and encrypted contents key data in which contents key has been encrypted. Only specific client terminal having selection key in key set (selected client terminal) decodes contents key from selection key to decode encrypted contents data caused to undergo stream distribution into contents data to perform real time reproduction thereof.

摘要： Methods and systems of distributing digital content governed by a digital license are provided. In one aspect, the license has identification data for licensed content and is transmitted to a client device. A first item of content is transmitted to the client after receipt by the client of the license. The first item of content has first content identification data, and at least a portion of the first item of content is in encrypted form. A second item of content is transmitted to the client after receipt by the client of the license. The second item of content has second content identification data that is different from the first content identification data. At least a portion of the second item of content is in encrypted form. The encrypted portion of the first item of content is decrypted if the first content identification data corresponds to the identification data for licensed content. Similarly, the encrypted portion of the second item of content is decrypted if the second content identification data corresponds to the identification data for licensed content. The identification data for licensed content remains unchanged after the license is transmitted to the client.
