Design of a Video Matrix Based on Embedded Operating System

Video switching technology requires switching system has good performance on real-time, easy for interacting and so on. The development of embedded system provides powerful support for video switching technology which make the embedded system technology become the research hotspot of this field. Light graphical user interface(GUI) as a necessary component of embedded system are also included inevitable. With embedded operating system on hardware platform, transplanting graphics libraries, compiling kernel-mode drive, we eventually set up the system. Using light graphic interface, multithread task allocation mechanism, signals and slots, message delivery, semaphore communication mechanism on the above system, we can meet the industrial demand on video matrix.
