Overview
Live and stored video-on-demand are among the most compelling and efficient forms of
human communication and removes the barriers of time and distance. Microsoft Windows
Media is a ubiquitous technology that makes it easier for VBrick customers to deploy video
for one-way video delivery to millions of PCs and multimedia-equipped devices worldwide.
"Windows Media" describes Microsoft's multimedia product technologies for Windows. It
includes (1) Windows Media Format tools for encoding and decoding audio and video, (2)
Window Media Services for publishing streaming audio and video on a server, and (3)
Windows Media Player, which is the client program that plays Windows Media and other
multimedia formats. The Windows Media Player is typically installed with the operating
system on most desktop PCs so no player-side installation is necessary, eliminating a
common IT concern when deploying a streaming audio/video solution. VBrick has licensed
Windows Media encoding and server technology from Microsoft and created the VBrick WM
Appliance to interoperate with other Windows Media compatible products including all
versions of Windows Media Player and all versions of Windows Media Server.
