FPGA is used to control ADV7183A so that ADV7183A can output the 8 bit 4:2:2 YCrCb video data.Then the data is sampled at every other point to produce the grayscale image data of 320×256.Finally,the data is transmitted to DSP.The sampled data displayed by DSP meets the demand of design and serves as good digital video data for later filtering.
