摘要:
A data distribution system that distributes data adapting to a second terminal from a first terminal having data to the second terminal. The first terminal includes a data recording means that records data of a plurality of formats, a data distribution request receiving means that receives a distribution request of data adapting to the second terminal and that receives a URL related to the information of the second terminal, a terminal information acquiring means that acquires the information of the second terminal from the URL, a data selecting means that selects data adapting to the second terminal on the basis of the acquired information of the second terminal, and a data transmitting means that transmits the selected data to the second terminal. The second terminal includes a terminal information describing means that describes the information of the second terminal in tree structure, a URL recording means that transmits the information of the second terminal described in tree structure to a predetermined URL to record the information, a data distribution request means that requests the first terminal to distribute data adapting to the second terminal and that notifies the first terminal of the URL, and a data receiving means that receives the data from the first terminal.
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.

There is disclosed image predictive coding apparatus and method, image predictive decoding apparatus and method, and recording medium which stores therein the image predictive coding method or the image predictive decoding method, of which the transform efficiency is remarkably improved in comparison with the prior art. According to the image predictive coding apparatus and method, when dividing inputted image data to be coded into image data of a plurality of small regions which are adjacent to each other and coding the image data of an objective small region to be processed among the image data of the plurality of divided small regions which are adjacent to each other, reconstructed image data of a reproduction small region adjacent to the image data of the objective small region to be processed is used as image data of an intra-frame prediction small region of the objective small region to be processed, the image data of the intra-frame prediction small region is used as image data of an optimum prediction small region and image data of a difference small region which are differences between the image data of the objective small region to be processed and the image data of the optimum prediction small region is generated. Then, the generated image data of the difference small region is coded and outputted, and then the coded image data of the difference small region is decoded, so that the reconstructed image data of the reproduction small region is generated by adding the decoded image data of the difference small region to the image data of the optimum prediction small region.

A quantization matrix used in inverse quantization is generated. A received bitstream includes a coded truncated quantization matrix. The coded truncated quantization matrix has first coded bits and second coded bits. The first coded bits include bits obtained by coding a transmitting part of quantization elements and the second coded bits includes bits obtained by coding an end code. The coded truncated quantization matrix is decoded until the second coded bits corresponding to the end code are read out, to obtain the transmitting part of quantization elements. At least one additional quantization element is obtained. A complete quantization matrix is generated, using the transmitting part of quantization elements and at least one additional quantization element, by ordering the transmitting part of quantization elements and at least one additional quantization element in a zig-zag scan.

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.

The present invention relates to digital item adaptation, especially MPEG-21 Digital Item Adaptation (DIA) which requires negotiation between different MPEG-21 peers. Advertisements metadata is defined to hold Digital Item Adaptation descriptions, such as Usage Environment description, BSDL description, XDI description, as well as MPEG-7 Media description in its descriptions element. With that, a generic DIA negotiation mechanism (protocol) using some XML schema based messages for DIA description transmission/exchange/update is defined. A generic and higher-level DIA Negotiation messages is also defined, which is independent from any network protocol, so that descriptions for Digital Item Adaptation can be directly included in the defined messages for registering, transmitting and updating to fulfil DIA description negotiation in those applications that is involved in digital item adaptation.
摘要:
This invention describes a way to represent IPMP scheme description for Digital Item to be used for MPEG-21 IPMP system. It aims to link IPMP with DID model of MPEG-21 framework. It also provides an interoperable and secure way for MPEG-21 IPMP system implementers to build the whole IPMP for Digital Item distribution and protection under MPEG-21 architecture. This invention also designs appropriate places to put the IPMP information including the important IPMP Tool related control information as well as other tool information. The information shall be put in DID Descriptor Statement at the beginning of Container, or tightly bound to the Resource element.
