Downloading and using RealOne

Introduction

The RealOne (formerly RealPlayer) plug-in is an application that allows streaming of audio and/or video over the Internet. For example, RealOne allows your Web browser to display multimedia content (a combination of text, sound, graphics, and/or video). RealOne allows for the playback, creation, publishing and live broadcasting of multimedia content over the Internet.

Basic Terms

streaming

Streaming takes media files (audio, video, etc.) and breaks them up into smaller packets to deliver to the destination computer. Instead of downloading the entire file before playing it, you can play it while it's downloading. This makes it possible to view live broadcasts over the Internet. For a detailed explanation of streaming media and how it works go to the RealPlayer 8 manual.


plug-in

Plug-in applications are programs that are downloaded and installed as part of your web browser. These supplementary programs allow your browser to play sound (if you have a sound card and speakers connected to your computer), video, and other functions. Once downloaded these applications are automatically recognized and opened by your browser when needed. If you visit a web site or attempt to access a linked file within a web page that needs a plug-in that your browser does not have, your browser will prompt you and provide a URL for accessing the needed application.

Activities

Instructions:

  1. Download and install RealOne onto your computer by following these step-by-step instructions.

  2. Read our instructions for using RealOne and then take a few minutes to explore the RealOne control bar (see figure 2). The RealOne controls look and work much like those of a music compact disk (cd) player. There's a button for play, stop, forward and backward. There is also a slide bar for progressing through the content--forward and backward and a volume control bar.
