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.
Note:
While streaming media files can be played on any hard
drive or CD-ROM, they require a special streaming media
server (provided by your ISP) to stream properly across the
Internet.
Important:
Windows Media Player 9 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.
