The Research Of User Interface Design In Digital TV Based On Multi-Screen Interaction

With the development of information and communication technology, the innovation of digital TV has step into a new era. Under the promotion of Three Nets Integration, digital TV is becoming a digital media terminal of television broadcasting, telecommunications and the Internet functions, providing services including traditional television programs, video-on-demand, current information, public service, electronic subscription, Internet surfing, games and applications. And the multi-screen interaction technology not only enrich the function of digital TV, but also allow people to watch and share multimedia such as TV program among multi-screen terminals such as mobile phones, computers, tablets and so on. The multi-screen function of digital has brought the users new multimedia interactive experience, greatly enrich the culture life and entertainment. Multi-screen interaction will gradually become the development direction of digital television.The application of multi-screen interaction in the digital TV has brought changes in contents, interactive way and application forms of digital TV. And the interface design in digital TV should be adapt to the innovation of digital TV. This research is based on the user interface design of digital TV with multi-screen functions.Firstly, summarize the development situation of digital TV and multi-screen interaction technology with the method of working on documents, products and cases. Secondly, studying the Influencing factors of the interface design in digital TV based on multi-screen interaction, including different screen characteristics, control methods, using environment, navigation, information architecture and the page layout of different multi-screen terminals from the perspective user interface design.Thirdly, studying the principles, methods of user interface design and apply it to the interface design case in this research. The case designed the user interface of a digital TV system based on both the TV set and mobile phone, including product positioning, interaction design, interface design and visual design. Through the case, the author summarized the relevant design methods, design processes and design rules of digital TV based on different multi-screen terminals.The Research summarize, analyze, explore the interactive ways and user interface design rules for digital TV based on multi-screen interaction, integrated theoretical study and application of practice. Providing the principle of user interface design for digital TV based on multi-screen interaction, in order to combine multi-screen technology and digital TV and to improve the interactive experience of digital TV users.
