RTSP implementation comparison
The following table describes RTSP implementations for Real Server marketed by Real Networks Corporation*, and Quicktime Streaming Server marketed by Apple Inc.* Their RTSP stream setup sequences differ, and the WSM handles each differently.
|
Real Server
|
Real Server's real media files have the following extensions: .rm, .ram, or .smil. Real Server supports both UDP and TCP transport protocols for the RTSP streams. The actual transport is negotiated during the initialization of the connection. If you specify TCP transport, then all streams of data will flow in the TCP control connection itself. If you choose UDP transport, the client and server negotiate a client UDP port ranging from 6970 to 7000 to set up each stream connection.

QuickTime Streaming Server
|
Apple Inc.'s QuickTime Streaming Server typically runs on Apple platforms. QuickTime files, which can be played over the Internet using RTSP, are specially formatted and are called hinted Quick-Time files. Normal QuickTime files cannot be used for streaming. QuickTime files have the extension .mov. QuickTime uses UDP protocol exclusively for transport and TCP for control connection. Each stream of a QuickTime presentation sends Real Time Protocol (RTP), and Real Time Control Protocol (RTCP) data using two UDP connections. Typically, a QuickTime presentation has two streams and therefore uses four UDP connections and one TCP control connection. QuickTime clients use a UDP port ranging from 6970 to 6999 for setting up stream connections.
