With the development of Smart planet and Intelligence Community. More and moreDigital Services are provided to citizen, to facilitate the daily life of urban resident. Digitalhome terminal is a traditional embedded devices, A device receiving one type of digitalservices. With the increase in the number of Digital Services, the mode of one terminal toreceive one type of Digital Services can not meet the demand.To meet the needs that the Technology of Multiple Digital Service Access. Now needthe mode of one terminal to receive a wide variety of Digital Services, adapt to a variety ofDigital Services’ UI. The topics was based on Intelligence Community. The definition andthe completion of the User Interface of Digital Services is separated. The providers of theDigital Services define the user interface and uploaded to the intelligence communityserver, the Intelligence community store the User Interface properties file. the Intelligencecommunity store and transform the packets of digital services. Digital home terminaldownload User Interface properties file and the User Interface resources from theIntelligence Community Server. Terminal parse the User Interface properties file todisplayed the user interface that the User Interface property file defined on the output ofthe terminal. Intelligence Community connect Digital Service providers and Digital Hometerminal, flexible driver technology shielding the hardware differences of Digital Services.To meet the demand of one Digital Home terminal receiving all types of Digital Services.A state machine displays a variety of the user interfaces of Digital Service.The system is suitable for multiple platforms. The system was tested on threeDigital Home terminal platform, from the testing results, the system had a goodapplicability on multi-access Digital Services, meet the demand of the Digital ServicesUser Interface display and work well on multiple Digital Home terminal platform.
