MPEG-7 se enfoca en representar informacion acerca del contenido y no de la codificacion del mismo, como es el caso de los estandares MPEG-1, MPEG-2 y MPEG-4 (JISC, s.f a), en otras palabras, MPEG-7 esta definido de manera tal que no dependa de como el recurso descrito esta codificado o almacenado, y por lo tanto, se puede aplicar MPEG-7 para describir recursos que no hacen parte del mundo digital, como por ejemplo una pelicula en soporte analogico (video convencional) o a una imagen impresa sobre un papel (Peig, 2003).
The new MPEG-7 technology will enable the selection of one or more information streams from a multiplex containing many such streams and, together with the MPEG-4 compositor, offer a means of flexibly presenting this information on screen.
Furthermore, while metadata is supported by really mature standardised schemas such as the one defined by MPEG-7, there is a clear need of defining a common schema of contextual information for generic multimedia scenarios.
The adoption of MPEG-7 [1] for describing metadata related to the digital items and of MPEG-21 [2] for describing metadata related to a governed content (i.e., with an associated license), as proposed in this paper, is a common approach used by an increasing number of scientific communities.
The MPEG-7 standard provides a set of tools to describe the important content needed for multimedia retrieval, decided by the MPEG Committee.
The MPEG-7 and MPEG-21 standards have been developed to support such requirements.
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.
The work will be undertaken within the context of the MPEG-4, MPEG-7 and FIPA standards.
ABSTRACT: In this paper we perform statistical data analysis of a broad set of state-of-the-art audio features and low-level MPEG-7 audio descriptors.
This volume examines the MPEG-7 and MPEG-21 standards that seek to consolidate and render effective the infrastructure for the delivery and management of multimedia content on the Web.
The current focus is on MPEG-7, the "Multimedia Content Description Interface," which will be completed this year.  This version of MPEG will allow the full search and retrieval of multimedia objects using its standardized description language based on XML.
Another version, MPEG-7, is aimed at indexing video and other media by content.
