Windows 2000 NT Plans Only

Real System G2 is not supported on Windows 2000 NT plans. We are running Windows Media Services. Windows 2000 NT supports the streaming of Windows media files such as .asf files.

Modifying Files

You will need to modify your .asx and .asf files as follows:

mms://www.domainname.com/userid/filename.asf

.asf files

.ASF files can be streamed from the users website by linking them inside of an .asx or .wax metafile. When a browser downloads a file with one of these extensions from a website, it opens Windows Media Player. Windows Media Player then locates and plays the content specified in the file.

A Windows Media metafile contains a type of Extensible Markup Language (XML) scripting that can only be interpreted by Windows Media Player. A metafile script can be as simple or complex as you need it to be. The most basic metafile contains simply the URL of some multimedia content on a server.

.asx files

.asx files can be created in notepad and the saved with a .asx extension. For example, a simple .asx file would be as follows:

<ASX version="3.0">
    <Entry>
        <ref HREF="mms://www.DomainName.com/userid/Path/FileName.asf">
    </Entry>
</ASX>

Users must insert their userid in the URL of the .asf file, if the file resides on our servers. If the User ID is not entered in the URL the MMS format will rollover to HTTP streaming format.

Updating and Creating .ram Files

Do I need to update my existing Real Audio/Video 5.0 .ram files to work with RealSystem G2?

Yes, to take advantage of the new features that RealSystem G2 offers, you will need to modify your existing .ram files as follows:

Current Format as supported by RealSystems G2:

• UNIX:
  rtsp://<yourdomainname>/userid/filename.rm
  rtsp://<yourdomainname>/userid/subdirectory/filename.rm
  rtsp://<yourdomainname>/filename.rm
  rtsp://<yourdomainname>/subdirectory/filename.rm

*Your existing RealAudio/Video 5.O .ram files will continue to work with the upgraded RealSystem G2 server. However, effective May 1, 2000 we will discontinue support of the RealServer 5.0.

I am currently using RealAudio/Video 5.O on Unix and the "~userid" format in the .ram file, will this work with RealSystem G2?

No, you will need to upgrade your .ram files to the RealSystem G2 format. It is important to delete the "~userid" and replace it with "userid".

How do I create a .ram file?

For each .rm file that you create, you will need to create a .ram file. First, use a text editor such as Notepad to create a text file with a .ram file extension. You should consider using the same file naming convention for example the "test.ram" file will launch the "test.rm" file. The .ram file should contain one line in the following format for both Unix and NT users:

rtsp://<yourdomainname>/userid/filename.rm

Substitute your domain name,& userid and the complete filename including the ".rm" extension. This file can reside in the root directory of your account.

Once the .ram text file is created, you should save it and upload it to your web site using ASCII as the transfer mode. If you are not familiar with uploading files, please see Uploading Files with FTP

Now that you have completed creating and uploading your .ram file, you should have both the .rm and the .ram files in your root directory.

How do I create the HTML code for a .ram file on my website?

The following HTML code can be inserting into your website's HTML source:

<a href="http://yourdomainname.com/(textfile.ram)">Click Here</a>

Please remember to substitute your own domain name and RealMedia file into the example HTML code above.

If you reference the .rm file directly from your HTML code, the file may play, but you will not benefit from the streaming media effect.

What mode should I use to upload .ram files to my website?

All .ram files should be uploaded in ASCII mode to the root directory of your website. If you are not familiar with uploading files, please see Uploading Files with FTP

Streaming Media

What is streaming media?

Streaming media allows you to send small packets of information over a network connection. The user receives the information packets and plays your clip little by little. The process is transparent to the user, except for a small amount of buffering at the start of the clip.

Streaming media can be either RealAudio or RealVideo. Before the concept of streaming media, users had to wait for a file to download from the Internet or a network server in order to play it. When you create streaming media, users can view it almost instantly.
