SMIL (Synchronized Multimedia Integration Language) l SMIL (pronounced “smile”) is similar to HTML, enables simple authoring of interactive audiovisual presentation. • SMIL is recommended by the World Wide Web Consortium(W 3 C) for integration of independent multimedia objects with a synchronized multimedia presentation (XML-compliant format; 6/98 – officially introduced) • A SMIL file allows the placement of both different images and a Power. Point file on different parts of the screen.
