Take a tour of SMIL, the Synchronized Multimedia Integration Language, and find out how you can use it to quickly and rapidly build Web-based multimedia offerings incorporating multiple media types.
SMIL files are based on XML, and therefore inherit all the attributes (and constraints) of that toolkit. An SMIL document consists of a series of nested elements, or tags, each one controlling some aspect of the final result. As with any XML document, element names are case-sensitive, and must be correctly nested in order for the document to be well-formed.
In order to see how this works, save this document with a
".smil" file extension - for example, "simple.smil" - and then pop open your copy of the RealOne player and load this file into it. Once the player parses the file, you should see something like this:
Not very exciting, huh? Don't worry - we'll jazz it up a little further down. For the moment, let's just dissect the code above and see what each of those elements actually does.
Every SMIL document must begin and end with a pair of <smil>...</smil> elements; everything contained within these elements forms part of the SMIL presentation. The XML namespace for SMIL should be included in these elements via the "xmlns" attribute.
The remainder of the document can broadly be divided into the
<head> and the <body>, in much the same way as a regular HTML document. The <head> contains metadata (a description of the media presentation or a copyright notice) and layout information, while the <body> contains the elements that reference the actual media content or set up timers.
