During the last ten years media streaming has found its way into our
computer desktops. Streaming services include everything from the
daily TV-news and personalized radio channels to on demand music
shopping. With the introduction of high-speed data communication
to mobile devices a lot of these services have begun to find their way
to the mobile market.
There are many ways of streaming media but one of the most
frequently used building blocks of these services is the Real Time
Streaming Protocol, RTSP. RTSP could be described as a remotecontrol
protocol in the sense that it provides VCR-like control
mechanisms to a stream.
This thesis describes the essential protocols needed for streaming. It
also describes the development of an extended RTSP client
implementation for the Obigo architecture and integration with an
existing media player. We also investigate the possibility to reuse
existing implementations for data delivery, media description and
The result of this thesis is a fully implemented RTSP client with one
extension protocol added. The client is integrated with an existing
media player in the Obigo architecture.
