A streaming media engine using digital item adaptation

Abstract

This paper describes the use of capability descriptors for MPEG-21 digital item adaptation. The capability descriptors describe the terminal and network for an application involving media resource delivery. The capability descriptors are used in a streaming media environment through a test bed demonstrating possible functionalities of a universal multimedia access (UMA) enabled system. The test bed involves viewer configuration through capability negotiations. The configuration triggers a media resource adaptation for accessing streaming media using a variety of access schemes on a diverse range of terminals. The application focus is towards future generation mobile and wireless multimedia communications, ensuring the user gets the same reliability and seamlessness as in a fixed environment.
