This chapter has provided a brief introduction to MPEG, an overview of the MPEG-4 standard, and a more detailed description of the architecture and tools of the MPEG-4 specification. These descriptions have been done from various perspectives: with a meme's eye, from a design and principle approach, and from an MPEG-4 document organization point of view, starting with the application or starting with the anatomy of an MPEG-4 browser.
The following chapters develop all the items that are crucial for audiovisual scenes authors, that is, all the technology that is related to the scene graph representation and its dynamic. They also approach the representation of individual media so that content authors are fully aware of the palette of tools that is made available to their creativity, allowing them to take what they need from the MPEG-4 standard.
Finally, the MPEG-4 specification reflects the results of teamwork within a worldwide project in which many people have invested enormous amounts of time and energy. The author would like to thank them all, and hopes that the experience and results achieved matched the level of their expectations. The best gratification for these people would probably be to let their brains consume compelling MPEG-4 encoded audiovisual memes. This book should help make this happen.
