Implementation And Verification Of Video Format Converter

Along with the development of digital processing TV and fully digitalized new-generation TV, video format conversion has become an important technology. In China it is time for varying from analog TV to digital TV in ten years. So it is essential that analog TV receiver can receive both digital TV and analog TV programs and at the same time digital TV receiver can also receive both programs. Video Format Converter in the paper focuses on this problem. In this paper we present an implementation of Video Format Converter based on a new method, which is interpolation method on motion estimation. Using by the method, we can convert well pixel number per line, period of line, frequency of frame and scan format (interlaced/progressive). The function of the Video Format Converter is to receive one type format video data from MPEG-II decoder and transform to another type format. The input and output video formats can be PAL, NTSC, SECAM, SDTV, HDTV etc.. The architecture of VFC is software reconfigure-able. That means that pixel number per line, period of line, frequency of frame and scan format (interlaced/progressive) can be changed by controller. In this paper we design a verification system for verification our design on FPGA. The verification platform is built based on the evaluation board that contains a signle Xilinx Virtex-â…¡ ProTM XC2VP20 FPGA. We design an embedded system (software and hardware) that connects the FPGA and a PC with EPP interface. The driver and test software are written with C/C++ Language.The Video Format Converter was designed in verilogHDL. And the verification was proceeded with on the hardware platform of FPGA.
