Synchronized Multimedia

In addition to basic audio and video content, RealAudio and RealVideo System allows you to create real-time on-demand multimedia presentations using the RMMerge tool (Windows or UNIX). These presentations can be as simple as a narrated slide show of your home page or as intricate as a multi-frame training program that the viewer controls.

RealAudio and RealVideo System includes the ability to synchronize World Wide Web pages with audio. Thus the audio can be used as a "time line" to display new pages or frames in the Web browser or to update its content. This enables the creation of Internet slide shows, presentations, guided tours and site walk-throughs. A user can have full random access (fast forward and rewind), and the Web browser content is synchronized with the audio.

RealAudio and RealVideo System stores the information for the synchronized events in a file with a .rm file extension. RealServer streams audio and event information to RealPlayer. The event information is streamed to RealPlayer, and in turn RealPlayer sends Web page information to the Web browser telling it to update the page's content.

Another way to create a synchronized multi-media presentation is using RealPlayer Plug-in. However, since sending the Web browser to a new URL unloads RealPlayer Plug-in when the HTML page is unloaded, it is best to create separate frames for RealPlayer Controls and for the changing images.
