Fpga-based Video Processing System

Nowday the digital television is springing up soon.But its prevalence needs a long time.In this process, we should not only take full use of the system of traditional analog televion we have,but also improve the quality of the picture of analog television. At present a new kind of TV set appears in the market.It 's based on the digital process technology,and we call it digital process TV set.It use various of the diagital methods to process the interlace,low field_rate signal,include the deinterlace,field_rate conversion and the methods of display enhance.The digital process chip of television signal is the core part of the digital process TV set.It integrates all the digital process,and is the key of the improvement of picture quality.In this paper I'll introduce the realization procedure of the video post process system based on the FPGA EP20K1500EBC-1 of Altera Co.And I'll emphasize the design of video input interface and modules of display enhance.
