VBrick WM Appliance Admin Guide 7
Push Reflecting from a Windows Media Server
The VBrick WM Appliance can push its Windows Media stream to a Microsoft Windows
Media Server or to a RealNetworks Helix Server which can then reflect the stream to players
or other servers using any of the protocols supported by the server.
T To reflect a pushed stream through a Windows Media or Helix server:
Create a broadcast publishing point on the Windows Media or Helix Server and configure it
for a "Push" source. In the WM Appliance Configuration: Encoder > Push
options configure
the VBrick to push the stream to the publishing point on the server or to a copy of the
publishing point on the server. When the appliance push is active, the server makes the
stream available to players or other servers via unicast and/or multicast, based on the
configured publishing point options on the server. The Push feature is useful in cases where
it is advantageous to have the VBrick send to the server instead of having the server request
from the VBrick (for example when the encoder is behind a firewall and the server is not).
For more information, see Creating Publishing Points
on page 48.
Pull Reflecting
For pull reflecting, the reflector is simply configured to act as a client that pulls the stream
from the source. A VBrick Reflector—either in the dedicated reflector model (9190-0200-
xxxx) or in the encoder/reflector model (9190-4200)—can pull from a VBrick Encoder, a
Microsoft Encoder, or it can pull live or stored content from a Microsoft Server.
Table 3. Typical Pull Reflecting URLs
T To reflect a pulled stream through a Windows Media or Helix server:
Create a broadcast publishing point on the Windows Media or Helix Server and use the
VBrick HTTP URL (i.e.
http://172.22.113.9:8080/vbrickvideo1) as the source of the
publishing point. The server requests the stream from the VBrick via HTTP and makes the
stream available to players or other servers via unicast and/or multicast based on the
configured publishing point options on the server. For more information, see Creating
Publishing Points.
Pull Reflector Type URL
VBrick Reflector pull URL for pulling an
HTTP stream from another VBrick:
http://vbrick_ipaddress:8080/vbrickvideo1
Pull from an .asx file served from a
VBrick or any HTTP server:
http://ipaddress/vbs1http.asx
Pull from a Microsoft Encoder:
http://microsoft_encoder_Ipaddress:port
Pull from a broadcast publishing point on
a Microsoft Server:
http://microsoft_server_Ipaddress/LiveStream
Pull from an on-demand publishing point
on a Microsoft Server:
http://microsoft_server_Ipaddress/videofolder/
storedvideo.wmv
Pull from a dynamically-generated or
load-distributed publishing point that
redirects the client to an .asx file or a WM
HTTP stream:
http://myserver.com/findURL.dll?myplaylist
