Adoption of the MPEG-21 digital broadcast item model (DBIM) towards QoS metadata management

MPEG-21 is a multimedia framework well suited for asset management of broadcast content. Especially for television broadcasters, MPEG-21 has been applied as asset management standard within the Digital Broadcast Item Model (DBIM). Within the scope of this paper, the DBIM is adopted to the needs of the IST IP ENTHRONE 2. ENTHRONE 2 devotes to the Quality of Service (QoS) management from content creation to content consumption over heterogeneous networks. This paper integrates the QoS metadata management issues from ENTHRONE 2 into the DBIM. This paper describes an MPEG-21 based metadata management solution for maintaining service quality throughout a heterogeneous network environment. It provides a metadata model based on the DBIM especially focusing on the needs of ENTHRONE 2.
