| Abstract: | A software solution for processing DVB teletext in terminal unit is given, and the modeling and designing process based on UML technology are introduced. Then, the key features such as page decoding, caching and navigating are analyzed. Meanwhile, the OS abstraction and page rendering call back mechanism are applied in order to satisfy the requirements of compatibility and portability. Finally, a universal teletext processing component is completed. |
