Windows Media® Streaming Over IP Networks
Delivering Windows Media® video and audio has never been easier. Whether it’s corporate training, a new product launch, or a dean’s speech at graduation, VBrick’s WM Appliance enables video delivery over your enterprise network or the Internet.

Capabilities
VBrick’s WM Appliance is based on the award winning VB6000 platform and provides multiple capabilities in one portable and reliable appliance.

Encoding
Digitizing and compressing a video signal for delivery over an IP network

Serving
Serve up to 200 live unicast streams or 20 on-demand streams - NEW

Multicasting
Multicast a live video directly from the appliance

Pushing
Push up to 25 simultaneous streams to VBricks or Windows Media® Servers - NEW

Reflecting
Receive a live stream over the network and deliver it locally via unicast or multicast - NEW

The Reflector functionality allows a WM Appliance to receive video over a low bandwidth link and retransmit onto a local area network. This important feature allows the VBrick to bridge low bandwidth bottlenecks by only delivering one video stream over the low bandwidth link and then delivering video to multiple end users at the far end. Other major new features include Multi Bit Rate (MBR) encoding, 16:9 support, and Closed Captioning support.

Recording
Record video that is being encoded or received over the network (requires optional hard drive)
