MPEG-4 authoring tool for the composition of 3D audiovisual scenes

Bringing much new functionality, MPEG-4 offers numerous capabilities and is expected to be the future standard for multimedia applications. In this paper a novel authoring tool fully exploiting the 3D functionalities of the MPEG-4 standard is described. It is based upon an open and modular architecture able to progress with MPEG-4 versions and it is easily adaptable to newly emerging better and higher-level authoring features. 1
