6.6. Summary

This chapter described the eXtensible MPEG-4 Textual Format (XMT) framework. The XMT framework consists of two levels of textual syntax and semantics: the XMT-A format, providing a one-to-one deterministic mapping to MPEG-4 Systems binary representation, and the XMT-Ω format, providing a high-level abstraction of XMT-A to content authors so they can exchange content with other authors while preserving their original semantic intent. XMT-A provides interoperability between VRML/X3D and MPEG-4, and XMT-Ω provides interoperability between SMIL and MPEG-4.
