Video summaries generation and access via personalized delivery of multimedia presentations adapted to service and terminal

摘要

This article is centered on describing the provision of universal multimedia access services for video summaries via multimedia presentations that allow the integration of multimedia messaging service (MMS)-enabled terminals in the framework of the deferred time environment (DTE) of the DYMAS system. The system uses the framework of MPEG-7 and MPEG-21 to provide description metadata of the multimedia content and the usage context (including terminal, network capabilities, and user preferences), respectively. These descriptions are the base for the main functionalities of the complete system that provides personalized access to content (filtering by user preferences or via querying) that is first adapted to a multimedia presentation (generating a video summary that is represented via keyframes with synchronized audio clips) by the Presentation Builder and afterward adapted to the current service and terminal by the Adaptation Engine.
