    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： The present invention relates to content and IPMP tool transfer among distributed IPMP devices. A set of messages is defined for distributed IPMP devices. These messages include content transfer message, IPMP tool transfer messages, as well device ID broadcasting messages. Using these messages, distributed devices can use a standard set of messages to establish a network, and exchange content protected by IPMP in an inter-operable way. It is also related to carriage of rights in MPEG system, especially in MPEG-4 system. Rights ES (Elementary Stream) is defined in MPEG-4 system, to carry rights information. The Rights ES is also attached with information including whether the rights carried in the ES is proprietary or not, and/or what should be the rights management tool to handle this Rights ES. With that, terminal can be built in an inter-operable way, and retrieve rights from a standardized position.

    摘要： An apparatus for a flexible and common IPMP System (Intellectual Property Management and Protection) offers flexibility and interoperability by incorporating a complete IPMP Tool List stored in the content stream or downloaded from a URL location. The IPMP Tool Manager of a compliant IPMP terminal functioning as a preprocessor module is provided, the IPMP Tool List is parsed, and an IPMP Tool is acquired based on the IPMP Tool ID, related location identifier, and IPMP Tool Format ID. The IPMP Tool can be precompiled to a binary format and sent or downloaded to the IPMP terminal, and different binary formats are prepared by the content provider for use on different IPMP terminal platforms.

    摘要： A method for appropriately defining standards for implementing an MPEG-n intellectual property management and protection (IPMP) system introduces IPMP Tool Information located at the beginning of the content stream, and an IPMP Tool management function as a pre-processing module located at the start of the content decoder, and retrieves IPMP Tools based on the IPMP Tool Information. To improve security and enable interoperability between terminals in different IPMP systems, a two-layer security structure and user authentication output format are further defined. Implementation on terminals of different complexity is enabled by further defining different profiles for IPMP Tool retrieval.
