Unicast Streaming

Updated: November 17, 2007

Applies To: Windows Server 2008

You can configure Unicast Streaming plug-ins in Windows Media Services to enable the distribution of content using unicast streaming, the default method by which a Windows Media server delivers content. A unicast stream is a one-to-one connection between the server and a client, which means that each client receives a distinct stream and only those clients that request the stream receive it. It offers the benefits of interactivity between a player and server, easier setup, and multiple-bit-rate (MBR) streaming capability. However, the number of users that are able to receive unicast streams is limited by content bit rate and the speed of the server network. For more information, see Delivering content as a unicast stream.
