scope:

The standard for digital media content description specifies digital media visual content descriptors to satisfy the requirement of searching in large-scale multimedia data and support applications to visual surveillance.

Purpose

The standard provides compact descriptors to represent the visual features and describe the category, attribute, property, and context information of the multimedia data, which can facilitate content searching and indexing, save bandwidth for transmission, enable hardware support for descriptor extraction and matching, ensure interoperability of multimedia applications and ubiquitous platforms, simplify design of visual application, and enhance performance on visual surveillance applications, which demand high bandwidth.
