  1. Introduction


This ‘MPEG-7 Applications Document’ describes a number of applications that are enabled by MPEG-7 tools. It certainly does not list all the applications enabled by MPEG-7, but rather gives an idea of the potential applications that could be supported.

The purpose of this document is to provide a better understanding of what the MPEG 7 standard is, and the functionality that could be delivered. In the past, this document was used as a tool to help write concrete requirements. For this reason, the earlier sections that describe the push/pull and other specialised applications not only include the description of the application provided, but also application-specific requirements and the requirements that were imposed on the MPEG-7 standard. These requirements are kept in place since they do indeed provide some important insight regarding the development of MPEG-7.

In October 2000, MPEG-7 reached the stage of Committee Draft (CD). This stage indicates a mature specification, and, for the first time, the specification is made publicly available. In section 7 of this document, applications that are based on actual descriptors and description schemes that are part of the specification are described.

2. MPEG-7 Framework


Today, more and more audio-visual information is available from many sources around the world. Also, there are people who want to use this audio-visual information for various purposes. However, before the information can be used, it must be located. At the same time, the increasing availability of potentially interesting material makes this search more difficult. This challenging situation led to the need of a solution to the problem of quickly and efficiently searching for various types of multimedia material interesting to the user. Moreover, MPEG-7 not only enables this type of search, but also enables filtering. Thus, MPEG-7 will support both push and pull applications. MPEG-7 wants to answer to this need, providing this solution.

MPEG-7, formally called ‘Multimedia Content Description Interface’, standardises:



  • A set of description schemes and descriptors

  • A language to specify description schemes, i.e. a Description Definition Language (DDL).

  • A scheme for coding the description

For more details regarding the MPEG-7 background, goals, areas of interest, and work plan please refer to document N2729, “MPEG-7 Context, Objectives, and Technical Roadmap” [1]. MPEG-7’s requirements and definitions are indicated in document N2727, “MPEG-7 Requirements Document” [2].

3. MPEG-7 Application Domains


The increased volume of audio-visual data available in our everyday lives requires effective multimedia systems that make it possible to access, interact and display complex and inhomogeneous information. Such needs are related to important social and economic issues, and are imperative in various cases of professional and consumers applications such as:

  • Education,

  • Journalism (e.g. searching speeches of a certain politician using his name, his voice or his face),

  • Tourist information,

  • Cultural services (history museums, art galleries, etc.),

  • Entertainment (e.g. searching a game, karaoke),

  • Investigation services (human characteristics recognition, forensics),

  • Geographical information systems,

  • Remote sensing (cartography, ecology, natural resources management, etc.),

  • Surveillance (traffic control, surface transportation, non-destructive testing in hostile environments, etc.),

  • Bio-medical applications,

  • Shopping (e.g. searching for clothes that you like),

  • Architecture, real estate, and interior design,

  • Social (e.g. dating services), and

  • Film, Video and Radio archives.
