We analyze the interconnection among WLAN, Internet, and Ku-band satellite communication networks. In order to meet the QoS requirements of the audio/video delivery, we have proposed an application-layer QoS control and testing method by using a frame rate and resolution adaptive modification algorithm. The simulation results show that the proposed method enhances the network utilization rate and has great QoS control capability of modifying the frame rate adaptively.
