Executive Overview :mpeg-7標(biāo)準(zhǔn)
MPEG-7 is an ISO/IEC standard developed by MPEG (Moving Picture Experts Group), the committee that also developed the Emmy Award winning standards known as MPEG-1 and MPEG-2, and the 1999 MPEG-4 standard. Mpeg-1 and MPEG-2 standards made interactive video on CD-ROM and Digital Television possible. MPEG-4 provides the standardized technological elements enabling the integration of the production, distribution and content access paradigms of the fields of digital television, interactive graphics and interactive multimedia.

MPEG-7, formally named “Multimedia Content Description Interface”, aims to create a standard for describing the multimedia content data that will support some degree of interpretation of the information’s meaning, which can be passed onto, or accessed by, a device or a computer code. MPEG-7 is not aimed at any one application in particular; rather, the elements that MPEG-7 standardises shall support as broad a range of applications as possible.

More information about MPEG-7 can be found at the MPEG home page (case sensitive):? and the MPEG-7 Industry Focus Group website http://www.mpeg-7.com/. These web pages contain links to a wealth of information about MPEG, including much about MPEG-7, many publicly available documents, several lists of ‘Frequently Asked Questions’ and links to other MPEG-7 web pages.

This document gives an overview of the MPEG-7 standard, explaining which pieces of technology it includes and what sort of applications are supported by this technology.
