基于Altera Cyclone IV E FPGA设计的TV-VGA转换控制器，采用Altera Cyclone IV E FPGA将DVD输入影像信号传输到DE2-115开发板电视译码芯片(ADV7180)，经过译码转换成8位的ITU-R标准接口影像数据传输到Cyclone IV E FPGA，ITU-R 656译码器将亮度与彩度信号分开、做解交错和缩放处理，并将亮度与彩度信号转换成VGA显示的红、绿、蓝影像信号，Cyclone IV E FPGA将影像信号传输到DE2-115开发板的VGA数模转换芯片(ADV7123)，最终实现通过LCD/CRT屏幕播放画面。仿真结果表明该转换控制器设计算法是正确、有效的。

Using Altera Cyclone IV E FPGA to send the input image signals of DVD to the DE2-115 development board of the TV decoder chip (ADV7180),after decoding,the image signals are converted into eight ITU-R standard interface image data ,then it will be sent to the Cyclone IV E FPGA, After separating the brightness signal and chroma signal by ITU-R 656 decoder, and then make staggered and zooming ,Then converting the brightness signal and chroma signal into the red, green, blue image signals of VGA display .After this, the Cyclone IV E FPGA will send the image signals to the DE2-115 VGA analog-to-digital conversion chip on the development board (ADV7123), Finally it is realized to the LCD/CRT screen images. The simulation results show that the conversion controller design is correct and effective.
