RealServer is designed on a new architecture that allows greater extensibility and interoperability with third-party solutions.
This version of RealServer includes the features described below.
The view source feature allows users of RealPlayer version 7.0 to view the source code for SMIL presentations or media clips. You can also browse the on-demand content available to your RealServer.

| Refer to "Displaying Source Code for SMIL Files and Media Clips". |
As you make changes to RealServer using RealSystem Administrator, those modifications that require you to restart RealServer are listed on a Pending Changes page. The Restart Server button at the top of the RealSystem Administrator window changes color to indicate that new changes are ready to be implemented, and a Pending Changes button appears as well.

Previous versions of RealServer did not archive SureStream files, nor could SureStream files be included in a simulated live event.

Scalable multicast now includes a feature that allows clients to receive unicast transmissions if their multicast connections fail.

Dynamically add a streaming advertisement to a requested media clip. Integrate with ad servers and services seamlessly.

As in versions 3.0, 4.0, and 5.0, RealServer 7.0 can segment its streams and host content on behalf of other users.

Version 6.0 introduced the ability to automatically limit the size of access logs. In RealServer version 7.0, error logs can also be limited.

This section lists the features which were new to RealServer version 6.0.
Previous versions of RealServer used an encrypted license key string, which was used during installation and placed in the configuration file, to indicate which features were available.
RealServer introduces new license files that allow for greater flexibility in upgrading available features.

RealServer includes RealSystem Administrator, a new HTML interface for working with nearly every aspect of Server operations. Use this tool to fine-tune RealServer features, monitor Server activity, and play sample presentations.
RealSystem Administrator can be accessed from any Web browser on the network. Security features for RealSystem Administrator are also included.

| See Chapter 7, "Customizing RealServer Features". |
RealServer now uses RealTime Streaming Protocol (RTSP) as its control protocol and RealNetworks' proprietary RDT as its packet protocol.
A visible change in this version of RealServer is the change in URLs that point to RealServer presentations.
rtsp://.

| See Chapter 5, "Understanding Link Formats". |
The configuration file, which stores all the settings used by the RealServer, is now in Extensible Markup Language (XML) format. This new format allows greater flexibility and extensibility by third parties. The file is easy to modify with the new RealSystem Administrator, or you can still use a text editor to make changes.

Additional Information |

| See Chapter B, "Configuration File Syntax". |
Most features are handled by separate files, called plug-ins. Located in the plug-ins directory, these plug-ins are read by RealServer when it starts and they control what happens to client requests. The RealServer open architecture allows third-party companies to develop plug-ins that can be added easily to RealServer for future functionality. This open architecture lends itself to modularity and customization.

In addition to the splitting method of previous versions, splitters can now rebroadcast material upon request.

RealServer allows you to limit access to RealServer based on the IP address of the requesting client just as earlier versions did, but RealServer adds the ability to restrict access to certain ports. In this way, you can better control traffic flow on your RealServer computer.

New options for verifying the identity of visitors to your RealServer presentations include Windows NT authentication.

Use the constantly updating Java Monitor in RealSystem Administrator. Zoom in for a closer look. Change the colors of the display.

| See "Java Monitor". |
If you have Windows NT, use the NT Performance Monitor with the RealServer rmserver.pmc file.

Additional Information |
|---|
| See "Optional Java Monitor Features". |
RealServer works with Windows NT User Authentication to give access to users who are already in the NT user group lists.

RealServer version 7.0 is fully compatible with RealServer 3.0 and later. Presentations created with earlier versions of RealSystem tools still work seamlessly with RealServer; place them in the Content directory. To use encoding software that was developed before RealSystem G2 version 6.0 (such as RealVideo Encoder 4.0), use the information in "Pre-G2 Encoders".
To use new features, such as RealText, in an existing presentation, you must update the presentation by creating a SMIL file and modifying the URL that refers to the presentation.
