| Facing the sweeping wave of global IT industry with intellectualized features, traditional electronic industry and mobile internet industry are stepping into a brand-new intellectualized time with each passing day.With the large quantity of cell-phones, tablet PCs and terminal equipment related being intellectualized,the smart TV is the focus for research in recent market which also attaines attentions of research institutions and electronic icons.Smart TV, which boosts specialized operating system and processing chips is capable of pursuing numerous medium resources while connecting internet. Likewise, it also provides application platform with these functions, which contains the download of application programs, fixing and simultaneous performing of multiple tasks.Under these circumstances. The mixed competence of multiple tasks could be catered to.Although smart TV could provide users with services similar to internet, for instance: surfing the internet, browsing websites, searching engine, and playing computer games ect. Smart TV serves as the processing center of multi-medium. Its primary function is to act as a tool, which could be convenient for users to handle multi-medium resources in an easy way.in order to meet the growing needs for users multi-medium resources handling.it becomes more indispensable to develop an application program to handle multi-medium resources on the basis of smart TV platform.The article use SAMSUNG smart TV development platform as project background, design and complete part of the presentation layer of the syetem module under the Widget Based Browser system frame work. The development of smart TV Widget Based Browser system is on the basis of developing SAMSUNG smart TV The system is virtually an application which runs in search engine of smart TV. By using the system.users can browse and handle the multi-medium files, which are derived from the certain equipment connected to USB device, such as:browsing and classifying and searching for photos.music and video files;editing album,music list.video play list;Playing the photo storage device;Music and video files. Extracting the photo location information and photos shot trajectory marked on Google Maps and so on The system adopts the technologies of HTML.CSS.JavaScript,XML and so on.Further development can be fulfilled with the help of Google Map API. The article’s mainly research objects are as follows:1. Describe and analy relevant technologies concerned and SAMSUNG Smart TV in the process of developing of Widget Based Browser system.2. Start the requirement analysis to Widget Based Browser System, including functional requirements, performance requirement and so on, taking full account of system extensibility and maintainability required to determine the framework of the whole system and module division.3. According to the system requirements analysis phase identified in the functional requirements we design the structural system of Widget Based Browser System with different layers. Then we detailed analysis and design the presentation layer modules, also we design the way of data encapsulation and processing.4. Use Web technology to complete some module in performance layer module for widget based browser system, such as photo player page and album edit page. Except that, we also implement combobox component, bubble tip component and photo view component. Finally, we demonstrate the instance of each module. |
