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. Purpose The standard aims to provide proper remote control and collaborating management solutions for operators@ community administrators@ public service providers@ government departments@ and individual users@ so as to use and control facilities in community and building groups effectively@ such as sensors@ surveillance monitors@ HVAC@ lighting systems@ fire-fighting systems@ consumer electronics@ and so on; The public environment monitor mechanism is set up to ease energy shortage and environment degradation through remote surveillance@ operation@ management@ and maintenance@ leaving a secure@ comfortable@ and convenient living environment. Energy@ environment@ and security are taken into consideration to realize reasonable plans and remote control in community networks.
