2. Can RealProducer G2 create content that is accessible by older Players?

   RealProducer G2 does not have the capability of creating backwards compatible streams. The ability to create content that can be accessed by G2 Players and previous Players is available in RealProducer Plus G2. This ability is part of the SureStream technology.

3. Where can I get information about creating RealVideo Content for live broadcasting?

   There are several places to obtain information about how to create RealVideo content for a live broadcast. One place which offers multiple sources of information about RealVideo and live broadcasting is from the RealSystem Producer Resources.

   An additional source for information is the Production Guide, available from the Documentation Library.

4. Can RealAudio and RealVideo files be streamed without a RealServer?

   Yes, in a limited fashion, RealAudio and RealVideo files can be streamed via the HTTP protocol without using a RealServer. To stream the files via the HTTP protocol, the metafile must specify http rather than pnm, and the Web server must be configured for the correct MIME types.

   There is documentation about the protocol and the process in the Knowledge Base and the Documentation Library. Another page with HTTP streaming information is available at http://www.realstore.com/source/source.html

5. How does the Web server need to be configured before files can be streamed using the HTTP Protocol?

   Before you can stream RealAudio and RealVideo clips via HTTP, the Web server must have the following MIME types defined:

   audio/x-pn-realaudio (files with a .ra, .rm or .ram file extension)
   audio/x-pn-realaudio-plugin (files with a .rpm file extension)
   

   Some Web servers are pre-configured with these MIME types. If you are using an ISP to host your site, send them email requesting that they configure their Web server with the MIME type information above.
