The platform of level of digital family system that Home E beautiful adopts at present is the standard of network of " China family that MII takes the lead working group " makes " standard of platform of system of Chinese family network " , this standard already recommended a level at was being approved formally to be national industry by MII in June 2005. The architecture of domestic network was made in this standard, it is domestic network cent network of information of high speed media and network of low speed control, united the communication agreement of network of digital family high low speed and standard, have detailed description and standard to agreement of the communication in network of high low speed.
Embedded operating system platform
The core component of digital family is domestic gateway, 32 when can use the framework such as ARM, MIPS embedded the hardware foundation that processor regards a family as gateway. Software uses modular design train of thought, can divide for software of network news report, application software and systematic software a few parts. The safety of the communication between the group network that software of network news report uses network of state of administrative family star, each node and network news report. Application software includes equipment management, control management, interface interface of program management, control, log management, call the police all sorts of application processes such as management, user management, safe attestation management.

Stone's throw is wireless communication
The family is wireless the network is one of a variety of family networks, will tell to digital family, the wireless technology such as use radio frequency or electric line of force avoids wiring, have very good removability, can the better application in getting used to a family. Be defeated by the differring of rate as it is said according to number, wireless network can divide the family it is 3 kinds:
High number leads short distance according to transmitting wireless family network (UWB, 802.11n, transmission rate is more than 100Mkb/s) , basically use at recreational network;
Moderate number leads short distance according to transmitting wireless family network (802.11a/b/g, transmission rate is less than 50Mkb/s) , basically use at data (file) transmission network;
Small number leads short distance according to transmitting wireless family network (802.15.4, blue tooth, transmission rate is less than 250kb/s) , basically use at monitor and controlling a network.
