To support multimedia services between network domains with different environments, it is required to map the functionalities in many aspects. In this paper, we implemented interworking gateway which provides protocol conversion and QoS(Quality of Service) adaptation to interwork DAVIC services based on ATM(Asynchronous Transfer Mode) network and Internet AV services. The interworking gateway converts RTSP(Real-Time Streaming Protocol) messages into DSM-CC(Digital Storage Media Command & Contral) messages to control the stream that is served in ATM network, and transmits data stream by using RTP(Real-time Transport Protocol). The interworking gateway provides QoS adaptation functionalities by QoS monitoring and MPEG filtering to meet the variation of network bandwidth.
