Can I stream videos that are accompanied by the textbook I use for class?
The video(s) that accompany a text book are copyrighted unless otherwise noted. Therefore, an formal letter must be sent to the publisher to request to stream the videos. The publisher will mail a letter back with an approval or denial of your request. If an approval letter is provided, then you may stream the video content.

What difference does it make if the content is streamed rather than downloaded ?
Audio and video files can be very large. You would spend many minutes or even hours waiting for them to be downloaded to your computer if they weren't streamed. Streaming media technology allows you to see or hear the content in just a few seconds, instead of having to wait for it. Your only wait is a few seconds for a "buffer" to be built up that helps avoid interruptions caused by Internet traffic problems.

Sounds Great! Is there a downside to streaming media?
There are some potential problems, but we'll tell you how to avoid or minimize them.

• Traffic jams. Streaming requires an Internet connection that's free of bottlenecks or "traffic jams." But the Internet isn't a direct pipeline from the source to you. Streamed content passes through many other computers on its way to your computer via your ISP. If any one of them is carrying too much other traffic, the streamed content may be interrupted and pause. Streamed content is "buffered" to help avoid this, but sometimes it's unavoidable. Usually the delay only lasts a few seconds, and the audio picks up where it stopped. Video is more sensitive to such interruptions.
• A slow computer. Even with a fast computer, if you have too many applications open, it could slow down your media streaming. If you notice things are sluggish, close all unnecessary applications and windows running on your computer. Just keep your Web browser and your media player open. (If you're just listening or watching, you can even close your browser.) In any case, speedy computers are better.
• Noisy phone lines. If you have a phone line that isn't free of noise (humming, crackling), that's not good for streaming (or Web browsing). Disconnect any phones that cause a buzz or hum. Have your phone company check your line to get rid of humming or other line noise. Of course, a cable modem or DSL connection is best for streaming media.

Why won't ACC's Real Media files play with the latest version of Real Player (v. 11)?
There is a codec compatibility problem. You should either download RealPlayer v. 10.5 or the Real Alternative player to view ACC's Real Media files.
