The Design And Implementation Of A Framework Applicable To A New Generation Media Terminal For TV

With the continuous development of information technology and the integration of new television, Internet, mobile network media, People have more diversified, individual and socialized consumer demands for video media, which derived many types of video carriers and terminals such as IPTV, Integrated machine, Internet TV, building TV, mobile TV, outdoor new media and so on. The establishment of application-oriented basic framework can make the application systems of various terminal devices compatible, which enhances reusability of terminal application system architecture and makes it could be built quickly. At the same time, it provides a set of framework classes to support the rapid development of granular products. Therefore, building a highly flexible, scalable, transplanted application-oriented basic framework to meet the development of standardized management on the same terminal equipment and the compatibility and adaptation between different terminal equipment, is an imperative trend for television new media terminal application development.The author of this thesis summarizes the general requirements for application components based on the characteristics of new media terminal application system, and describes that how to finish the architecture design and implementation of the terminal application framework in a detailed way. The main content of this thesis is as follows:Firstly the author introduces the application status and background of television new media terminal, emphasizes the need to build application-oriented framework, and establishes the basic objectives of framework construction, the author also clarifies different business scenarios and detailed cases of new media terminal horizontal applications, and further refines the requirements and boundaries of the framework architecture. On this basis, the author describes the main ideas and methods of framework construction, analyzes and realizes the overall architecture of the application framework, together with the stratification, collaboration and division of functional components of the framework. Secondly, the author makes a detailed analysis and implementation on the infrastructure layer, the core component layer, and also analyzes from the perspective of scene-aid analysis, application security and so on based on the Android platform. The infrastructure layer simplifies the development of generic modules of granular products, and facilitates the deployment and application of a basic module as the subsequent system-level components. These components are separated and decoupled, which greatly simplifies the underlying application system architecture. The construction of common core components simplifies the process of building new applications, reduces the complexity of application development, and enhances the independence and portability of logic components, which ensures that the focus of the key application development work is on the business logic layer. The design of analysis-aided components guarantees the continuous track and improvement of product quality, in which way makes the instant feedback of front-line services application possible. The analysis and realization of application framework security secures the major parts of the framework.Constructing the new media television terminal application framework improves the development of terminal applications, standardizes the model of application development and enhances the stability, compatibility and security of the products. In this way, it helps the products gain advantages in the market and provides powerful supports for the rapid development in the future business models and scenes.
