Introduction

RealPlayer G2 includes a Netscape plug-in and ActiveX control that expose RealPlayer functionality. This lets you play back a RealSystem presentation directly in a Web page without launching RealPlayer as a separate application. You simply add <EMBED> tag or <OBJECT> tag mark-up to a Web page. The embedded presentation typically includes an image window and one or more standard RealPlayer interface elements, such as the Stop button, the volume slider, and so on.

RealSystem G2 Production Guide available at http://service.real.com/help/library/index.html explains the basics of embedding a presentation.

	Additional Information
RealSystem G2 Production Guide available at http://service.real.com/help/library/index.html explains the basics of embedding a presentation.

Using a scripting language such as JavaScript or VBScript, you can use RealPlayer functions such as the stop, play, and volume controls without using RealPlayer's standard interface components. You can use your own graphic image for a Stop button, for example. When a user clicks the button image, a stop command is sent to RealPlayer's Netscape plug-in or ActiveX control. This document describes all the supported methods and events for extending RealPlayer's embedded functionality.

RealSystem Components

You need the following tools to create and test your embedded presentation:

RealPlayer G2
Use RealPlayer G2, available free at http://www.real.com, to test your JavaScript or VBScript extensions. Installing RealPlayer G2 also installs its Netscape plug-in and ActiveX control for embedded playback. The RealPlayer G2 installation includes a ZIP file with Java classes for use with the Netscape plug-in.
RealServer
RealServer streams clips to RealPlayer. RealServer is not necessary for testing local playback of embedded clips, but is necessary for streaming presentations to RealPlayer G2 over a network. RealServer Administration Guide is available at http://service.real.com/help/library/index.html.
RealSystem G2 Software Development Kit (SDK)
The RealSystem G2 SDK is not necessary for extending RealPlayer's embedded playback features, but is required for advanced programming tasks such as building a new client interface on top of the RealPlayer G2 core. A knowledge of C++ programming is required to use the SDK. Register for and download the SDK at http://www.real.com/devzone/.
