The Active Service Environment Management system (ASEMA) provides best possible multimedia service experience to end user. One of the main aspects of the ASEMA is to provide a variable live streaming service to the end users of the ASEMA. The ASEMA implements this through dynamic change in the properties of the video stream delivered to the end user's end device. The live video stream used in the ASEMA is delivered to the end users is in MPEG 4 video format. The video itself is streamed on top of the real time protocol (RTP) and the parameters are negotiated with the real time streaming protocol (RTSP) before the streaming commences. The research problem of this is to provide easy solution for QoS measurements in networks that are closed nature. The research is based on the constructive method of the related publications and the results are deducted from the constructed quality of service management of the ASEMA system. The management is founded on the measuring of the receiving and sending bit rate values in both ends, in the sending end and in the receiving end. If a fluctuation in the values are detected the video stream's properties are changed dynamically.
