scope:

Specifies a system for the communication of interactive audio-visual scenes. This specification includes the following elements: 1. the coded representation of natural or synthetic, two-dimensional (2D) or three-dimensional (3D) objects that can be manifested audibly and/or visually (audio-visual objects) (specified in part 1,2 and 3 of ISO/IEC 14496); 2. the coded representation of the spatio-temporal positioning of audio-visual objects as well as their behavior in response to interaction (scene description, specified in this part of ISO/IEC 14496); 3. the coded representation of information related to the management of data streams (synchronization, identification, description and association of stream content, specified in this part of ISO/IEC 14496); and 4. a generic interface to the data stream delivery layer functionality (specified in part 6 of ISO/IEC 14496). 5. an application engine for programmatic control of the player: format, delivery of downloadable Java byte code as well as its execution lifecycle and behavior through APIs (specified in this part of ISO/IEC 14496); and 6. a file format to contain the media information of an ISO/IEC 14496 presentation in a flexible, extensible format to facilitate interchange, management, editing, and presentation of the media.
