heal.abstract	This paper describes extensions implemented on the MPEG4IP streaming platform, to exploit Differentiated Services. These extensions are based on concepts of proposed QoS frameworks and are implemented by exploiting platform communication capabilities. Within this context, a Packet-marking layer component is introduced performing packet Type of Service (ToS) marking. In the case of live streams, semantics are captured in real-time during encoding, and propagated to the transmission layer. In the case of pre-encoded streams, information about the semantics is included in the media file metadata and provided as hints to the streaming server. Furthermore, a Video Quality Study component enables the user to preview loss effects on a video stream before its transmission, by simulating packet losses during encoding. In this way new video quality metrics and packet marking algorithms can be investigated. The applicability of certain QoS policies on the extended platform is experimentally evaluated over a Differentiated Services testbed. © Springer-Verlag Berlin Heidelberg 2003.	en
