scope:

This part of ISO/IEC 14496 specifies system level functionalities for the communication of interactive audio-visual scenes. More specifically:

1. system level description of the coded representation of natural or synthetic, two-dimensional (2D) or threedimensional (3D) objects that can be manifested audibly and/or visually (audio-visual objects);

2. the coded representation of the spatio-temporal positioning of audio-visual objects as well as their behavior in response to interaction (scene description); and

3. the coded representation of information related to the management of data streams (synchronization, identification, description and association of stream content).

4. a system level description of an application engine (format, delivery, lifecycle, and behavior of downloadable Java byte code applications); and

5. a system level interchange and storage format of interactive audio-visual scenes.
