Using command markers in streaming media files 
Command markers add interactivity to media streamed over the Internet by inserting metadata into streaming media files. As your file 
plays, any number of other actions can be programmed to occur. These commands are a part of the Windows Media Audio, Windows 
Media Video, and RealMedia streaming formats. Most frequently, these actions add text or open a related Web site. 
Command markers can also indicate when an instruction (function) occurs in a WAV file being used in a radio broadcast environment 
(Scott Studios data). The following two sections define the markers for both streaming media and Scott Studios files. 
Notes: 
•  While streaming, media files can be played on any hard drive,  CD drive, or DVD drive. They require a special streaming media server
(provided by your ISP) to stream properly across the Internet.  
•   Windows Media Player 9 and later will ignore metadata commands unless the Run script commands when present check box is 
selected on the Security tab of the player's Preferences dialog. Be sure to instruct your audience to select this check box before playing 
your file. 
Defining streaming media commands 
In a streaming media file, command markers can be used to display headlines, show captions, link to Web sites, or any other function 
you define. Some command types are exclusive to either the Windows Media files or RealMedia files.
