摘　　要：针对串行数字接口(Serial Digital Interface,SDI)的超高清数字视频信号无法测试的问题,基于虚拟仪器技术,在Visual Studio和LabVIEW开发环境下,将DeckLink 8K Pro视频采集卡作为音视频信号采集模块,开发超高清数字视频分析仪,实现SDI接口超高清数字视频信号的视频参数和音频参数的测试,并给出彩条、非线性失真、多波群频响及伴音等项目的测量过程和实现方法,通过实验论证,达到预期效果。In response to the issue of the inability to test the ultra-high definition digital video signal of the Serial Digital Interface(SDI),based on virtual instrument technology and in the development environment of visual studio and LabVIEW,using the DeckLink 8K pro video acquisition card as the audio and video signal acquisition module,an ultra-high definition digital video analyzer was developed.The video and audio parameters of the SDI interface's ultra-high definition digital video signal were tested,and provided the measurement process and implementation method for items such as color bars,nonlinear distortion,multi wave group frequency response,and accompanying sound.Through experimental verification,the expected effect was achieved.
