NIST contributes to development of next generation multimedia standard MPEG-7. (News Briefs).NIST (National Institute of Standards & Technology, Washington, DC, www.nist.gov) The standards-defining agency of the U.S. government, formerly the National Bureau of Standards. It is one of three agencies that fall under the Technology Administration (www.technology. actively participated in the development of the MPEG-7 Multimedia Content Description Interface standard, which was released at the Moving Picture Experts Group (compression, standard, algorithm, file format, body) Moving Picture Experts Group - (MPEG, ISO/IEC JTC1/SC29 WG11) An ISO committee that generates standards for digital video compression and audio. Also the name of their algorithms. (MPEG (Moving Pictures Experts Group) An ISO/ITU standard for compressing digital video. Pronounced "em-peg," it is the universal standard for digital terrestrial, cable and satellite TV, DVDs and digital video recorders (DVRs). ) meeting in Thailand in December 2001. The MPEG-7 standard provides standardized, core technologies allowing metadata description of audio-visual data content in multimedia environments. A NIST scientist provided MPEG-7 schema and sub-schema validation for the ISO/IEC ISO/IEC International Organization for Standardization/International Electrotechnical Commission (ITU-T M 3000) multimedia description scheme; MPEG-7 sub-schemas included description definition language DDL (Description Definition Language) is part of the MPEG-7 standard. It gives an important set of tools for the users to create their own Description Schemes (DSs) and Descriptors (Ds). , visual, audio, and W3C 1998 XML Namespace. A new web-based NIST MPEG-7 validation service (http://m7itb.nist.gov/m7v) has been set up to help MPEG-7 developers validate their encoded MPEG-7 metadata online. Recently, the NIST scientist initiated new work in MPEG to develop an MPEG-7 interoperability test bed to provide a validation process for encoded MPEG-7 metadata for conformance and interoperability testing between MPEG-7-based applications and to verify applicability of MPEG-7 technology in a real application or production environment. The NIST scientist is the chair of the newly established MPEG-7 Interoperability and Profiling Group and co-chair of the MPEG-7 Applications and Promotion to Industry (MAPI (Mail API) A programming interface from Microsoft that enables a client application to send to and receive mail from Exchange Server or a Microsoft Mail (MS Mail) messaging system. Microsoft applications such as Outlook, the Exchange client and Microsoft Schedule use MAPI. ) group within the MPEG standard body. In addition, the NIST scientist has recently been nominated to head as Vice President of the MPEG-7 Alliance an industry forum to help industry to transfer and adapt the MPEG-7 technology, and serves as the webmaster for the MPEG-7 website (http://mpeg-industry.com).
