Specifies a Namespace-based Validation Dispatching Language (NVDL). An NVDL script controls the dispatching of elements or attributes in a given XML document to different validators, depending on the namespaces of the elements or attributes. An NVDL script also specifies which schemas are used by these validators. These schemas may be written in any schema languages, including those specified by ISO/IEC 19757.

The Extensible 3D (X3D) specification, ISO/IEC 19775, specifies a language-independent application programmer interface (API) to a set of services and functions. For integration into a programming language, the X3D abstract interfaces are embedded in a language dependent layer obeying the particular conventions of that language. ISO/IEC 19777-2:2006 specifies such a language-dependent layer for the Java programming language.

Specifies the requirements for the operation of the Biometric Registration Authority within the Common Biometric Exchange Formats Framework (CBEFF). The Registration Authority is responsible for assigning and publishing, via its website, unique biometric organization identifier values to organizations that own or are otherwise responsible for standardized or proprietary format specifications for biometric data blocks, biometric information record security blocks and/or CBEFF patron formats, and to organizations that intend to assign biometric product identifier values to their products.

Standardized biometric data interchange formats are crucial to the interoperability of biometric components. Describes general aspects of biometric data interchange formats and specifies requirements to be taken into account in standardizing specific formats. It classifies biometric data according to their processing level and establishes a naming concept for biometric data interchange formats on this basis.

Specifies requirements for the representation of local or global spectral data derived from a fingerprint image. The format is designed to provide flexibility in the choice of spectral representation in that spectral components may be based on quantized co-sinusoidal triplets, Discrete Fourier Transformations or Gabor filters. The format also allows for a variable number of spectral components to be retained, which enables data representations in a form that is more compact than storage of the entire fingerprint image. Provides example data records for each of the spectral representations.

ISO/IEC 19794-8:2006 specifies the interchange format for the exchange of pattern-based skeletal fingerprint recognition data. The data format is generic, in that it may be applied and used in a wide range of application areas where automated fingerprint recognition is involved. The exchange format defined in ISO/IEC 19794-8:2006 describes all characteristics of a fingerprint in a small data record. Thus it allows for the extraction of both spectral information (orientation, frequency, phase, etc.) and features (minutiae, core, ridge count, etc.). Transformations like translation and rotation can also be accommodated by the format defined herein.

Establishes general principles for testing the performance of biometric systems in terms of error rates and throughput rates for purposes including prediction of performance, comparison of performance, and verifying compliance with specified performance requirements. Specifies performance metrics for biometric systems. Specifies requirements on test methods, recording of data and reporting of results. Provides a framework for developing and describing test protocols, to help avoid bias due to inappropriate data collection or analytic procedures, to help achieve the best estimate of field performance for the expended effort, and to improve understanding of the limits of applicability of the test results. Applicable to empirical performance testing of biometric systems and algorithms through analysis of the matching scores and decisions output by the system, without detailed knowledge of the system's algorithms or of the underlying distribution of biometric characteristics in the population of interest.

Specifies the syntax and semantics of tools that may be used to process Digital Items. Digital Item Methods: Tools enabling users to include sequences of instructions for adding predefined functionality to a Digital Item. Digital Item Methods are authored with the Digital Item Method Language, an extension of ECMAScript language (ISO/IEC 16262), which includes a normative set of Digital Item Base Operations. The predefined functionality specified by a Digital Item Method provides a suggested interaction between a User and the Digital Item. Digital Item eXtension Operations: Provide for extended functionality not included by the normative set of Digital Item Base Operations to be implemented efficiently in a higher level programming language. Linkage with ISO/IEC 21000-2: Tools for integrating Digital Item Methods and Digital Item eXtension Operations with Digital Item Declarations (as specified by ISO/IEC 21000-2).

This part of ISO/IEC 21000 specifies - how to express Event Report Requests (ER-R) that contain information about which Events to report, what information is to be reported and to whom; - how to express Event Reports (ER) which are created by an MPEG-21 Peer in response to an Event Report Request when the conditions specified by an ER-R are met.

Specifies a mechanism to monitor events associated with the manipulation and usage of Digital Items, as defined in ISO/IEC 21000-2, and Peers. Monitoring the usage of audio-visual digital material and gaining insight into the state or capacity of a Peer is an important functionality for many content creation, delivery, adaptation and consumption applications. Specifies a dynamic mechanism which allows Users to create an Event Report Request within a Digital Item which can then be processed by a Peer. Such an Event Report Request specifies the conditions when an Event Report will be first generated and then sent to a (set of) recipient Peer(s). Specifies the syntax and semantics of Event Report Requests (ER-R) and of Event Reports.

ISO/IEC 21000-17:2006 specifies a normative syntax for Fragment Identifiers to be used in URIs (Uniform Resource Identifiers) for addressing parts of any resource whose Internet Media Type is one of: audio/mpeg; video/mpeg; video/mp4; audio/mp4; application/mp4. ISO/IEC 21000 (MPEG-21) defines an open framework for multimedia delivery and consumption, with both the content creator and content consumer as focal points. The vision for MPEG-21 is to define a multimedia framework to enable transparent and augmented use of multimedia resources across a wide range of networks and devices used by different communities.

Specifies a number of image and video coding related standards include a requirement for decoders to implement an integer-output 8x8 inverse discrete cosine transform (IDCT) for the generation of inverse-transformed sample differences with a nominal range from -2B to (2B)-1 for some integer number of bits B, where B is greater than or equal to 8. ISO/IEC 23002-1:2006 specifies conformance requirements for establishing sufficient accuracy in such an integer-output IDCT implementation. It is intended to be suitable for reference to establish partial or complete requirements for IDCT accuracy for conformance to other standards that require IDCT use.
