摘要
Real-time multimedia services are transmitted over a hybrid network including a nonguaranteed quality of service packet switched local area network and a circuit switched ISDN wide area network having a centralized multimedia bridge located within the wide area network. The local area networks and multimedia bridge are interconnected via ISDN routers. An algorithm executed by the multimedia bridge receives signals from the packet switched network and detects the absence of properties needed for real-time audio visual services. The data signals are processed to compensate for the absence of the properties and then are transmitted over the wide area network to enable real-time audio visual services.
