Generic-model-based description scheme for MPEG-7

We propose a new description scheme for MPEG-7: Generic-model-based Description Scheme to describe contents of audio, video, text and other sorts of multimedia. It uses a generic model as the description frame, which provides a simple but useful object-based structure. The main components of the description scheme are generic model, objects and object features. The proposed description scheme is illustrated and exemplified by Extensible Markup Language. It aims at clarity and flexibility to support MPEG-7 applications such as query and edit. We demonstrate its feasibility and efficiency by presenting applications: Digital Broadcasting and Edit System (DEBS) and Non-linear Edit System (NLES) that already used the generic structure or will greatly benefit from it.
