摘要
由于HDMI是数字方式传输,它可以从根本上解决现行的机载雷达采用电视体制的PAL制或VGA制式的模拟信号在用于液晶显示时的要经历先D/A后A/D的变换所带来的损失,因此,提出用该种显示方式用于机载雷达的显示,此方法可大幅度地提高分辨率且无传输和变换损耗,本设计使用SiI9134为接口器件,数字视频形成电路由FPGA构成,实验证明此设计稳定可靠,完全可以达到产品要求。
HDMI is the abbreviation of High Definition Multimedia Interface and the standard for transmition of uncompressed digital audio or video streams.For the digital transmition of HDMI,it can solve the problem of losing information from A/D or D/A transform which happens before the PAL and VGA analog signals are displayed on the LCD.Therefore,we propose this standard on the display of Airborne radar with the advantage of high definition and non loss from tansmition and transform.We use SiI9134 as interface device and FPGA for the forming circuit of digital video.It shows that this design is stable and reliable,which achieves the product requirements.
