    摘要： An apparatus of a flexible and common MPEG-2 IPMP system (Intellectual Property Management and Protection) is invented to provide flexibility and interoperability by introducing a IPMP Control Information which includes IPMP Tool List and an optional Tool Container. The IPMP Control Information is put in PSI in MPEG-2 transport stream, and a special PES packet in MPEG-2 program stream. IPMP Stream is defined to carry IPMP information that is to be sent to each individual IPMP tool instance. The concept of Tool Manager, Message Router from MPEG-4 IPMP extension is mapped into MPEG-2 terminal to form MPEG-2 IPMP framework together with introduced IPMP Control Information and IPMP Stream. As a result of this invention, the same protected MPEG-2 content is able to play back by different types of MPEG-2 IPMP terminals, and the same MPEG-2 content can be protected by using different vendors' IPMP system.

    摘要： A method of transferring information specifying an IPMP tool utilized for processing a content protected by IPMP to an IPMP terminal specifies and uses XML schema for terminal platform specification, parametric description, and parametric aggregation which is to be used in MPEG-n IPMP system. For example, according to the method, based on a predetermined terminal platform XML schema and language to describe a terminal platform, terminal platform specification is created based on the terminal platform schema and language to specify on what platform or terminal the IPMP tool can run. The terminal platform specification is attached to metadata associated with the tool. The terminal platform specification and the IPMP tool are transferred to an IPMP terminal which is implemented with a terminal platform parser based on the terminal platform schema and language.

    摘要： In a digital content protection system for legally transmitting encrypted digital content from a transmitting device to a receiving device, unique device identifiers for devices are registered to a specific server in advance. The server also stores in advance information relating to an authentication method usable by each device, associating the information relating to an authentication method with the unique device identifiers. The transmitting device determines whether an identifier unique to the second device is stored on the server. When stored, the transmitting device determines that the receiving device is legal and determines from the server the appropriate authentication procedure. When the transmitting device has the determined procedure, the transmitting device uses this procedure to verify the authenticity of the receiving device. When the transmitting device does not have the determined procedure, the transmitting device acquires the authentication procedure from a source external to the transmitting device and then uses the acquired procedure to validate the receiving device.

    摘要： This streaming system includes a server and a client which transmit and receive a media stream having a layer structure including at least a session layer through a network. The server includes means for incorporating management information for managing the media stream in an SDP of the session layer of the media stream, and means for transmitting the SDP in which the management information is incorporated to the client in the session layer of the media stream. The client includes means for receiving the SDP in which the management information is incorporated from the server, means for extracting the management information from the received SDP, and means for managing the media stream on the basis of the extracted management information.

    摘要： MPEG-n IPMP system with a wide interoperability is provided. For this purpose, the IPMP_Data_BaseClass is defined, several IPMP data extending from this base class are also defined. IPMP data is the data that describes IPMP information, it includes: IPMP_OpaqueData; IPMP_SelectiveDecryptionMessage; IPMP_AudioWatermarkingInit; IPMP_VideoWatermarkingInit; and IPMP_KeyData. Places where IPMP data extending from IPMP_Data_BaseClass are also specified. With the above work, a IPMP tool from Vendor A will be able to understand the IPMP data constructed by Content Author B, hence the inter-operability will be achieved, that is, the same protected content will be able to be consumed on different vendor's MPEG-n IPMP terminals.
