The standard describes a remote control architecture of digital community, intelligent building groups, and digital metropolitan networks; specifies interactive data formats between devices and systems; and gives a standardized definition of equipment, service services, signals, and interactive messages in this digital community network. The digital community remote control network opens application interfaces for public administration, public services, property management services, and individual service services, which enables intelligent interconnection, collaboration service, remote surveillance, and central management to be feasible. Surveillance networks, consumer electronics, remote service systems, public administration systems, security linkage systems, and emergency reaction systems will be integrated into the community network seamlessly. Based on TCP/IP open systems, the network architecture adopts active and emerging technologies, supporting diverse access technologies in the physical layer, supporting IPv4/v6 in the network layer, and integrating well with the next generation converged networks.
