Abstract


Digital home services provide multimedia entertainment, communications and health services that make people's lives more convenient and colorful. Many studies have predicted the digital home service will have broad market prospects. With the development of information technology, the rapid spread of the Internet and communication technology continues to evolve, both in the promoters of the three networks (cable networks, telecommunications networks, the Internet) integration of the home network to provide video, voice and data integrated multimedia services, digital home business diversification. For digital home, we study the digital home network environment and the communication process. Details of the digital home video communication services; e-commerce, online payment, stock trading and other financial services; family security linkage value-added business services. Through the development of interfaces with third-party value-added service platform interconnection, including the realization of e-government, virtual communities, SNS, even if the communication access other third-party value-added services and implementation. In this paper, a home network environment, based on triple play and digital home intelligent terminal operations system platform, from the home network terminal equipment, information, intelligence needs, as well as the integration of the family business and other aspects of the trend of research and development. Focus is on the family business applications and multimedia content display expansion capacity requirements, develop and deploy scalable, multi-platform business operations and achieve Kara OK streaming media on demand business systems. Digital Home Kara OK system is mainly divided into two parts, the server and set-top boxes, the server reads the global configuration file to create memory, message, log files and other resources, then initialization tasks, enter the event processing loop. STB software implementation uses the Linux kernel source code to build an embedded software platform ONTOS, the platform includes an operating system, middleware and application software. Underlying operating system uses the standard Linux kernel, developed for digital 3C devices without modifying any application can be run directly on the platform; middleware JAVA virtual function that contains the database and facilitate the expansion of a variety of applications, and to facilitate porting existing large number of mobile phone Applications for home users with rich business. Kara OK function digital home support playback controls: start, play, pause, etc., supports UPnP protocol within the home network to share resources.
