Universival Asychronous Receiver/Transmitter（通用異步串行口），UART 是一種較為通用的數據傳輸的方法（即Start Bit＋Data＋Check＋StopBit），而COM 口中Rx、Tx 的數據格式即為UART。UART 和RS232是兩種異步數據傳輸標準.計算機中的COM1和COM2都是RS232串行通信標準接口。當Uart 接口連到PC 機上時，需要接RS232電平轉換電路。

目前市面上的SDI轉HDMI方案只有三種：一種是GV7601+SLI9022的方案，這種方案由于GV7601已經停產，所以賣的價格特別貴，而且新IC GV7704發出信號9022已經不能直接接收，所以這個方案逐漸也會消失。第二種是FPGA+SLI9022的方案，這種方案由于SDI RX是有FPGA實現的，所以兼容性肯定不如Gennum的好。重要的是，FPGA只能傳輸40-50米。第三種是GV7704+CV8788來實現的方案，這種方案價格便宜，兼容性也好，可以傳輸120米。此文檔就是第三種構架，請參考
