F or more about the specific co nfiguration set tings on the VBric k, see Configuration: Encoder on page 23 and Configuration: R eflector on page 57.
Introducti on VBrick WM Appliance Admin Guide 7 Push Ref lecting from a Windows Media Ser ver The VBrick WM Appliance can push its Windows Media stream to a Microsoft Windows Media Ser ver or to a Rea lNetw orks Helix Ser v er which can then reflect the stream to players or other ser v ers using any of the protocols suppo r ted b y the ser ver .
8 © 2008 VBrick Systems , Inc . Other Considerations Keep in mind these additiona l details . T he VBrick Pull R eflector : • Supports up to five redirects . • Supports the first (or only) HREF entr y in an .asx file. Additional entries in the file are ignored.

Th e follo wing table shows the configuration output settings that are shar ed between all video encoders, and the output settings that can be configured independentl y for each one .
Introducti on VBrick WM Appliance Admin Guide 11 T able 6. Aud io R at e S et ti ng s MBR Groups VBrick's implementation of m ultiple bi t rate supports the conce pt of groups. Groups ar e used in a unicast environment where the VBrick WM appliance is being used as a serve r .
12 © 2008 VBrick Systems , Inc . This feature is useful when you w ant to config ure MBR on the appliance with a high bit rate group for LAN HTTP access and at the same time ha ve a ser ver pull a lo w bit rate group for reflecting . Y ou can also use it to test play bac k for a particular group .
Introducti on VBrick WM Appliance Admin Guide 13 Group to match the requ est exactly . T his closest match ap proach is also used when the player requests a "thinned" video st ream, because the VBrick does not support video thinning .
