Aimed at the requirement of super-resolution, high definition, distortion-free in multi-screen splicing display system, a real-time digital video processing algorithm based on FPGA is proposed. After introducing the architecture of DVI interface screen splicing display system and function of the FPGA algorithm, according to the characteristic of video pixel streams, it is discussed the partition algorithm of real-time digital visual pixel streams, and the interpolation algorithm based on moving window operator. By verification, the algorithm can fulfill requirement of screen splicing display system. At last, the further research work is provided.
