Video overlay technology has been widely used in avionics display systems, high-speed flight state aviation aircraft can quickly and accurately without jitter display specific goal of becoming a video display technology research. The traditional DSP-based image overlay technology, high-power, and real-time image transmission efficiency is low, with the development of avionics technology, which increasingly difficult to meet the real-time display of video signals aviation aircraft. The design of the traditional DSP video processing hardware platform, constructed an improved video capture capture platform, and the corresponding hardware implementation logic, and achieve the results, and the results show that the design and smooth screen video overlay display technology without jitter, with good superposition effect.
