Welcome to RealText, part of RealSystem G2, which lets you stream multimedia presentations over a network. With RealText you can stream text from files or live sources. You can create presentations consisting of text alone, or combine text with other types of media to create, for example, closed-captioned video. This guide tells you how to use the RealText mark-up language to format streaming text for playback in RealPlayer.
You will need the following tools to create and test your RealText presentation:
To create a RealText file, you can use any word processor, text editor, or XML editor, that can save output as plain text.
Use RealPlayer, available free at http://www.real.com, to test your RealText presentation. Other applications may also have RealPlayer features that enable them to receive RealText as well.
RealServer streams your RealText presentation to RealPlayer. If you are not operating RealServer yourself, you need to have access to RealServer through, for example, an Internet Service Provider (ISP).
To broadcast text live, you integrate an application that captures the live text feed, adds RealText mark-up to it, and sends it to RealServer. You need the RealMedia SDK to do this.
In addition to this manual, you may need the following RealNetworks resources, available at http://www.real.com:
This manual explains the basics of streaming files with RealSystem. It tells how to calculate bandwidth needs and shows how to put a multimedia presentation together.
The basic reference for the RealServer administrator, this manual explains how to set up, configure, and run RealServer to stream multimedia. You need this manual only if you are running RealServer yourself.
The RealMedia SDK lets you integrate applications with the RealSystem. You need the SDK and its documentation if you want to broadcast RealText live to create, for example, a real-time stock ticker. A knowledge of programming is required to use the SDK.
The following table explains the conventions used in this manual.
