摘要
针对目前进口8K超高清视频信号发生器价格高昂引起的超高清视频相关产品的检测成本较高问题,选用低廉的视频采集卡作为系统硬件,通过使用厂家提供的软件开发包对其进行编程,开发低成本的8K超高清视频信号发生器,实现高清多媒体接口(High Definition Multimedia Interface,HDMI)2.1和串行数字接口(Serial Digital Interface,SDI)12G×4接口的8K超高清视频信号的产生和发送。依据检测标准,编制音视频测试信号,验证了设备的可用性。
In view of the high detection cost of ultra-high-definition video-related products caused by the high price of imported 8K ultra-high-definition video signal generators at present,a low-cost video acquisition card is selected as the system hardware.By programming it using the software development package provided by the manufacturer,a low-cost 8K ultra-high-definition video signal generator is developed.The generation and transmission of 8K ultra-high-definition video signals of the High Definition Multimedia Interface(HDMI)2.1 and the Serial Digital Interface(SDI)12G×4 interface have been realized.According to the testing standards,audio and video test signals were compiled to verify the usability of the equipment.
