Microsoft® Windows Media is both a storage format and a streaming format. In addition to the ability to
output to a file, the Windows Media encoder can stream to a Windows Media Server. The settings for
Windows Media encoder include the ability to set parameters for connecting and streaming to the
server.
Some Windows Media Capture Profiles have pre-defined video resolutions and input selections. When
you select a Windows Media Capture Profile, verify your current video and audio settings have not been
modified. If they have been modified, simply change these settings back to their previous settings and
click Save Settings.
When streaming audio and video, there are two methods of delivery:
 Pull – The system begins to generate broadcast packets as soon as you start the encoding. However, it
does not deliver the broadcast stream until Windows Media Server requests the stream. This method
does not provide a secure connection to the server. Only use this method if the encoder and server
reside within the same network firewall.
 Push – The system maintains a secure connection to Windows Media Server. This connection allows
the system to pass a user name and password to authenticate access to the server.
To enable clients to pull the stream from the system, set up a session and begin broadcasting directly
from the system. Clients (Microsoft® Windows Media servers or players) can connect to the stream at
any time by using the following URL format:
 http://IP_address:port (for Internet connections)
 http://encoding_computer_name:port (for LAN connections)
By default, the Niagara 9100 series systems support up to 50 direct connections each during a
broadcast.
Note: The more direct connections to the system, the more system resources are required. ViewCast
does not recommend directly connecting players to the system. Streaming servers should connect
to the system and, in turn, players should connect to the servers.
Use the following table to configure the output digital input settings for a Windows Media encoder.
Note: The choices in the drop-down list may vary.
