This application allows for the authoring of audiovisual presentations that are interactive. The SMIL is typically used for multimedia or ’rich media’ presentations that incorporate streaming video and audio with images or texts or other forms of media. The SMIL is a HTML-Like language and most of the SMIL presentations are handled by the use of a text editor. Its MIME types are application/smil and application/smil+xml.
The file extension SMI file SMIL is a protocol that is entirely dedicated to the presentation of multimedia over networks. This protocol enables the layout regions, development of timelines and options, for instance a user can serve different production versions depending on the type of bandwidth that a user has. The productions of the SMIL are more often than not delivered across ‘channels’ almost similar to television. The SMIL, being an XML based utility, can be authored or displayed by the use of the RealPlayer products (more likely over time), GRiNS, and HPAS.
