1 Introduction

The Real-Time Streaming Protocol (RTSP): Windows Media Extensions are used for transmitting real-time multimedia data such as audio and video data from a server to a client.

RTSP streams multimedia from Windows Media Services to Windows Media Player or other instances of Windows Media Services. In its primary application, the client is a multimedia player which will render or play the data, but the protocol can also be used for distributing data between two streaming media servers.

RTSP Windows Media Extensions use TCP and UDP.
