MPEG-4 supports object-based interactive multimedia applications. To compose complex multimedia scene, MPEG-4 supports BIFS and XMT as scene description. For interoperability of the MPEG-4 content and object-based rendering information management, this paper proposes the content analyzer that supports multiple scene description. In order to improve content management’s efficiency, the content analyzer provides module optimization from scene description’s parsing to scene information management. This analyzer supports exact analysis of the scene description and object-based core information management. And it can be applied to XML-based heterogeneous players.
