QuickTime Streaming Server

QuickTime Streaming Server (QTSS) was a server component developed by Apple to provide QuickTime and MPEG movies from an Xserve machine. It was included as part of Mac OS X Server until version 10.6.8 (Snow Leopard).

Deprecation
With the deprecation of QuickTime 7 as of Mac OS X 10.7 (Lion), QTSS has been superseded by HTTP Live Streaming for QuickTime X and Darwin Streaming Server, an open source version of QTSS.
