Whether the digital images can be displayed completely and correctly on CCIR interface is related with image storage,construction of timing signal,standard conversions and simulations of image data.A wildly used scheme of CCIR display interface is presented,in which the progressive scanning CCD image data can be converted to be the interlaced scanning data by SRAM.The timing design of composite sync and blanking by FPGA is given.And the application of video D/A converter and the problem of electromagnetic compatibility(EMC)are expatiated.The scheme can be widely applied in digital video systems,processing of high resolution color graphics and video representations.
