SMIL 1.0 provides a "test-attribute" mechanism to process an element only when certain conditions are true, for example when the language preference specified by the user matches that of a media object.

Synchronized Multimedia Integration Layer (SMIL), pronounced “smile", is a graphics language based on the Extensible Markup Language (XML) that enables TV-like multimedia presentations. SMIL is an XML language that content authors can use to create TV-like multimedia presentations for the Web that will be played on browser plug-ins such as Real's RealOne player.

Example of what you can create with the new VisualScript V2.0 - multimedia presentations with text annotation - simply drag and drop the fades and wipes you want, attached your digital image, add text, then generate - to your choice of two target players.

One of the many uses of SMIL is to add text captions to video or audio content. At this time, Real provides the best documentation and support for the use of SMIL for text captions, using its XML-based RealText format. The major problem here is finding the documentation on Reals indecipherable and annoying website!

This appendix will help you utilize the many features of RealSystem and SMIL. Before following the production tips given here, make sure you have a good understanding of SMIL as described in Chapter 7.

When you stream more than one clip, you use SMIL to lay out the presentation. The layout defines where each clip appears in the RealOne Player media playback pane. Clips might appear side-by- side, for example, or stacked on top of each other. This chapter introduces you to SMIL's basic layout features. Before you create a layout, be sure to read "SMIL File Basics".

SMIL Introduction

SMIL basics (15 minutes)

Most markup, such as RealText and RealPix, can use color names and hexadecimal values for color attributes. SMIL 2.0 supports the color values defined in the Cascading Style Sheets 2 (CSS2) specification, letting you use RGB values as well.

To present QuickTime movies synchronized with captions, or QuickTime-friendly SMIL documents on the Web, you can simply put a link to the media source. However, by applying the <object> and <embed> tags, you can provide more advanced features for user interface control on the presentation.

Thank you for using RealOne Player! This guide explains RealOne Player clip types, such as RealVideo and RealText, and covers the use of the SMIL 2.0 standard, along with the RealNetworks extensions to SMIL 2.0.

Different SMIL players are available. To view the examples contained in this tutorial, you'll need the G2 Player from RealNetworks. The free version of the software will suffice for our movies. You'll also need WinZip to unzip the SMIL clip prior to playing it. Download and install the G2 on your PC (no Mac version is available yet). Once you have it installed, read more information about playing the accessible SMIL clip.

This archive is divided into several sections. The first section is the fun stuff, a growing collection of SMIL demos that we have found to be quite inspiring!

This is a working draft of a specification of animation functionality for XML documents. It is part of work in the Synchronized Multimedia Working Group (SYMM) towards a next version of the SMIL language and modules. It describes an animation framework as well as a set of base XML animation elements, included in SMIL and suitable for integration with other XML documents.

A SMIL file takes the place of a RealSystem 5.0 .ram file and has three main purposes:

This Section defines the SMIL content control module. This module contains elements and attributes which provide for runtime content choices and optimized content delivery. Since these elements and attributes are defined in a module, designers of other markup languages can reuse the functionality in the SMIL content control module when they need to include media content control in their language.

The theme of xmlconference2003 is "Now We're Cooking!", symbolizing the many stakeholders in the business of developing and helping individuals learn to use XML and related systems such as SMIL for multimedia presentations. The emphasis in this presentation is to invite into the kitchen more media specialists, developers, and trainers who want to reach the widest feasible range of users. While WYSIWYGs are efficient for some tasks, real control comes only with direct coding.

SMIL is based on XML, which is more rigidly structured that HTML, but it uses the same familiar <tag> and </tag> syntax.

This document has been prepared by the Synchronized Multimedia Working Group (WG) of the World Wide Web Consortium. The WG included the following individuals:

Embedding a presentation in a Web page provides seamless playback without launching RealPlayer as a separate application. You can even include RealPlayer controls such as fast forward and pause. This chapter explains how you add mark-up to a Web page so that people view your RealSystem presentation directly through their Web browsers.
