本文提出了一种基于FPGA的模拟视频检测系统系统的设计方案。该方案首先将复合模拟视频CVBS进行数模转换,BT.656格式的数字视频连接到FPGA,FPGA进行BT.656数字视频解码,并对其内容进行分析。本文对广播电视播出应用中关心的黑场、彩条、静帧等情况应用FPGA实现检测的技术进行了阐述。实验结果表明,在一块ALTERA cyclone 2c8 FPGA芯片上可以实现4路模拟视频的分析。 This paper presents a FPGA-based analog video detection system design. The program first composite analog video CVBS digital to analog conversion, BT.656 format digital video connected to the FPGA, FPGA for BT.656 digital video decoding, and its content analysis. This paper describes the application of FPGA to detect the black box, color bar, static frame and so on which are concerned in the broadcasting and TV broadcasting applications. Experimental results show that in an ALTERA cyclone 2c8 FPGA chip can be achieved four analog video analysis.
