Streaming delivers media from a server over a network to a client in real time, from modem rates to broadband. No file is ever downloaded to a viewer’s hard drive. Media is played by the client software as it is delivered.

About Streaming Servers

If you want to send streams to people over the Internet or a local network, you need a streaming server. Just as you need a web server for web pages, and a mail server for email messages, you need a streaming server to send real-time streams.

The streaming server transmits video and audio streams to individuals in response to requests from those individuals using client software such as QuickTime Player. The requests are handled using Real-Time Streaming Protocol (RTSP), a protocol for controlling a stream of real-time multimedia content. The streams are sent using Real-Time Transport Protocol (RTP), a transport protocol used for transmitting real-time multimedia content over networks. A streaming server can create streams from QuickTime movies stored on a disk. It can also send copies of any live streams to which it has access.
