Design And Realize On Digital Television Screen Display System's Graphical Custom Software Of Renesas

With the development of embedded system technology, all kinds of embedded applications on the man-machine interface requirements have become more sophisticated, which makes the demand for embedded graphical user interface, more and more pressing. Digital TV As the prospects the 21st century one of the industries most extensive of its interactive interface development has been more and more attention. Therefore, Research and development of with self-ownership digital television graphic software platform has important theoretical significance and wide application.Currently, the research and application on the digital television technology of our country is still at the initial stage. Digital television display technology is one of the key of digital TV, its core is superimposed text in images, simple images, so that the display screen to provide users with more additional information for the user convenience. It defines and standardizes the application of information displays and interactive way, is the digital TV receiver software development focus.The project background of embedded software platforms, based digital television in the screen display technology, mainly to complete the following work: On digital television display technology architecture, technical features and trends analysis, digital television graphic design custom software systems; research and analysis of the WPF and its event handling mechanism, combined with digital TV business requirements, proposed uITRON operating system based on embedded digital TV graphic custom software solutions and implementation was carried out to complete the relevant test. The design of the graphical controls, graphical controls operational stability control, and embedded operating system code file generation aspects of the reverse route used to trigger the event, LinQ Data processing technology. Meanwhile, the process full use of the thinking of the software engineering.The digital TV's interface become more flexible and easier to third-party, when the software has been completed. Software display side using WPF, the virtual elimination of traditional control mechanisms, users no longer need to use traditional Button, Textbox and other controls. Achieve the desired results.
