MPEG Multimedia Content Description Interface (MPEG-7)

Published by International Organization for Standardization; developed by Moving Picture Experts Group.

MPEG-7, unlike MPEG-1 and MPEG-2, is a standard for the description of the content of multimedia files, rather than a format for the multimedia files themselves. It is intended to provide structures for data both for human and machine users. The standard provides “description schemes” for a wide variety of uses. In addition to the high-level descriptions of content that will allow search and browse, there are description schemes for the creation process, rights information, technical information, user history, and low-level features such as color, lighting level, and sound timbre.
