• Microsoft Windows Media Player 7.1 (Windows 98 or 2000 only); Media Player 9, 10, or 11 (Windows XP only). Standard Features The VB6000 WM Appliance supports approximately 40 Mbits/sec total throughput via the Ethernet/IP connection. This bandwidth can be used for any of the standard features shown in Table 1 but the overall performance of any one of these features can be affected by the sum total. For example, you can download more content from the hard drive when the encoder(s) are not

One of the major benefits of the VBrick WM Appliance is it's compatibility with the Microsoft ecosystem; this makes it easy to integrate with existing Windows Media installations. Table 2.

The Microsoft Windows Media 9 product suite divides transport functionality between two distinct products—the encoder and the server. In some applications the VBrick WM Appliance provides the same functionality as the Microsoft encoder in that it can encode live video and audio and provide a unicast stream to a Microsoft Windows Media server which then may relay the stream to the many players using various transport protocols. In other applications, the VBrick WM Appliance replaces both the

Introduction • Use an HTTP or RTSPU URL to get the unicast stream. You can create a web page that links to the HTTP or RTSPU stream directly or you can open the HTTP URL or RTSPU URL using Windows Media Player or a web browser. • Use an HTTP URL to access the .asx file on the VBrick. You can create a web page that contains an HTTP link to the HTTP or RTSPU asx file on the VBrick or you can open the asx URL using Windows Media Player or a web browser. • Use VBrick StreamPlayer Program Guide.

Reflecting from VBrick Appliances This section provides more information about how to use VBrick appliances in reflecting applications. For more about the specific configuration settings on the VBrick, see Configuration: Encoder on page 23 and Configuration: Reflector on page 57. A VBrick Reflector can reflect an HTTP Push from a VBrick Encoder, a VBrick Reflector, or Microsoft Encoder or it can pull an HTTP stream from a Microsoft Server, a Microsoft Encoder, a VBrick Encoder, or a VBrick R

Introduction 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. 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 Applianc

Other Considerations Keep in mind these additional details. The VBrick Pull Reflector: • Supports up to five redirects. • Supports the first (or only) HREF entry in an .asx file. Additional entries in the file are ignored. • Only pulls streams via HTTP. It will accept an MMS URL but will use HTTP for streaming from that URL. • Cannot pull multicast. • Cannot pull from a server-side playlist. Using Multiple Bit Rate Streams A VBrick WM Appliance (v4.0 or higher) has three internal video enco

Introduction combinations of audio and video rates for multicasting, HTTP and RTSPU serving, HTTP Push, and Archiving. See the Configuration: Encoder pages for more information. The following drawing shows the selectable output streams from a WM appliance. (Note that the Archive output on the right is actually a .wmv file rather than a stream.) Depending on your requirements and what you select, the VBrick will produce any or all of these outputs. Each output can be configured with different

Output Description HTTP/RTSP Unicast streams are provided via the VBrick internal server. In order to use Unicast this feature, you first create up to three groups, each of which consists of an audio stream at a selected rate and video stream at a selected rate, and optionally closed captioning and metadata. Some or all of these groups are Enabled on the Configuration: Encoder > Server page. The end-user client then determines whether to pull a specific group from the server or to negotiat
