No matter from internet TV across to intelligent TV, or the rise of digital home interactive services, based on digital TV interactive service platform which the needs of supporting application is more and more obviously, domestic digital home industry develop rapidly, and, face with the needs of application service developing, digital home application interactive system has a very big research value and significance. This paper focuse on researching digital TV application interaction system which has changed the traditional way of TV ’s control mode, that showing a new interaction experience. The interactive system construct the network system with IP technology,and the main structure of C/S architecture,that which by the server system and the client software in two parts.This paper designing a clear , safety and stability interactive system which on the present situation and requirement of the development of digital TV.First that would be starting from several key techniques. With open architecture,the system solutions which application content’s security controls can be undertaked and the terminal client can be designed by combining human-machine interactive.By implementation of the interworking of third party content providers with internet,and by the same time building the open architedure that the multiparty security being designed by the system terminal equipment safety module, terminal control module and security authentication security module,which providing control support for third party service providers. In human-computer interaction which unifies the gyro technology have changed the way of traditional control, on the expansion of interactive service function,make the digital home terminal users to enjoy human-computer interactive services. Through practice and comparison results shows that the interaction system can solve the shortage of openness ,improving the compatibility and security and good human-machine interaction problems,that can make up for the shortcoming and the insufficiency of other interactive platforms.The system’s open architecture meets the diverse content, integrating variety of multimedia entertainment, having diversification interactive services.and accessiing to more abundant and convenient information services ,it can break bottlenecks to address the digital TV content service integration.
