Understanding SMIL

About SMIL

SMIL (Synchronized Multimedia Integration Language) is an XML-compliant markup language that lets you lay out

and synchronize the playing of multiple streaming and static media items in a multimedia presentation. For example,

you can create a SMIL presentation that plays streaming video, streaming audio, images, and streaming text at the

times and in the sizes and positions you specify. You can create hotspots that link specific areas and time periods in

your presentation to other media source files, web pages, or other SMIL presentations.

SMIL presentations play in RealNetwork’s RealPlayer. You can specify whether your SMIL presentation plays in a

separate RealPlayer window or within the browser window, using the RealMedia plug-in.

Note: For SMIL specifications, see the W3C website (www.w3.org). For more information on using SMIL presentations

with RealPlayer, see the RealNetworks website (www.realnetworks.com).

SMIL presentation types

You can create three types of SMIL presentations in GoLive:

SMIL documents Let you create a layout for your various media items.

RealPlayer documents Let you add various media items to a pre-designed multi-pane layout. RealPlayer

documents combine RealMedia files (including all SMIL presentation types) and HTML content.

RealPix documents Let you create a slide show of still images. RealPix presentations can be stand-alone or included

as content in RealPlayer and SMIL presentations.
