The Research And Implementation Of Digital Process Television Based On STLite/OS20 Real Time Operation System

The Project realizes DPTV based on STLite/OS20 real time operation system(Digitalized Processing Television). DPTV receives analog signal and separatevideo signal and audio signal. Then the system converts the signal to digital signaland process the digital signal in digital field. At last DPTV converts the digitalsignal to the analog signal and display. The advantage of DPTV than analog TV isthe video and audio signal are processed in digital field. Through the process ofvideo and audio in digital field we can make the display more exquisitely and makethe sound more reality. The system can be compatible with high definition signal.DPTV have the best future in TV field. The project is based on ST20 real time operation sytem. The RTOS is multiplethreads and multiple tasks. So the speed of signal process is very high. Thestructure of the software has character of hiberarchy and modularization. Thecharacter is convenient for transplant and management and update. We can easilytransplant the software to other display terminal such as LCD display. The project hasbeen completed. We realized all the function of DPTV in this system. The system canbe product in factory.
