The Research Of Digital TV Receiver Based On EMMA2SL

Digital television, one of the best promising industries, has been greatly promoted in the worldwide. Digital television's reception technology has become one of the most essential pillar technologies and the research on the digital television's reception technology is conducted on this basis.The design and implementation of receiver of the digital television system are mainly elaborated in the paper. The thesis firstly introduces digital television's worldwide development and development tendency of the receiving equipment in digital television as well as hardware and software designing solutions of the receiving equipment. Hardware debug is then discussed and solutions for the common problems are raised based on author's working experience. Moreover, detailed analysis is conducted on the structure of the software system and the design and implementation of the applied software and the research on the embedded real-time operating system Rx4000 is carried out in the thesis. In the development of operating system the debug method is of great importance. Therefore, detailed research on debug method through JATG is carried out in the paper in the hope that the development duration can be shortened at large extent. Two indispensable links in the reception technology of embedded system including Chinese display solution and DiSEqC switch applied programs design are elaborated. At last the implementation of EPG is depicted and then EPG design and implementation is studied.
