Metadata Management and Personalization of audiovisual content using MPEG-7 and MPEG-21 standards in a distributed framework

摘要

This paper describes a partial development of the "i2CAT Machine Project", a project that builds a complete framework of media publication and consumption, where users can share audiovisual contents in a secured, adaptive and personalized way, following the concept of Universal Multimedia Access (UMA). Our work focuses on the module in charge of the content metadata storage and management which is called Metadata Management & Personalization (MM&P) module. It embraces content cataloguing, advanced searches, session mobility, strategies for content adaptation, user actions tracking, and it is envisaged to provide content recommendations based on user preferences in the near future. To reach this goal, the module provides extensive use of MPEG-21 and MPEG-7 standards ensuring interoperability with other similar systems.
