RTSP files can be used to broadcast anything from online radios to online conferences.

The Real Time Streaming Protocol is used by Apple to control the delivery of data over a network. Furthermore, RTSP controls real-time transfer of data such as video and audio streaming. RTSP files, sent by a BlackBerry, are used to stream audio and video content from various sources. The official software that works with RTSP files and can open them is Apple's QuickTime Player, which is a free tool.
