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.
Streaming with Real Audio and Real Video Files
Real Audio/Video streaming
rstp://www.domainname.com/userid/subdirectory/filename.rm is not supported under
the Windows 2000 platform. However, .rm files may still be played using standard HTTP
streaming methods. For example:
http://www.DomainName.com/subdirectory/filename.rm

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:
Old Format as supported by RealAudio/Video 5.O:
- UNIX: pnm://<yourdomainname>/~userid/filename.rm
- NT: pnm://<yourdomainname>/userid/filename.rm
New Format as supported by
RealSystem G2:
- UNIX: rtsp://<yourdomainname>/userid/filename.rm
- NT: rtsp://<yourdomainname>/userid/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.
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.

Uploading RealMedia Files
What mode should I use to upload .rm files to my
website?
All .rm files should be uploaded in Binary mode
to the root directory of your website.
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.

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.
