基于FPGA的高清晰度电视显示器测试信号发生器的研究与实现

Study of Testing Picture Generator for HDTV Monitor Based on FPGA

对第一代高清晰度电视(HDTV)显示器测试信号发生器进行了重大改进,把由14片IC实现的数据存储阵列放进了现场可编程门阵列(FPGA)中,从而提高了FPGA的利用率,节省了成本,并提高了系统的可靠性.本仪器的功能仍是实现满足4种HDTV视频标准的中国电影电视行业推荐的13种测试图案.

A great improvement was made in the first-generation testing picture generator in HDTV monitor. Fourteen IC chips were put in FPGA and the function of these chips was performed by the FPGA. The utilization factor of FPGA was enhanced. The reliability of the system was ensured and the cost was reduced. The function of this apparatus was to generate four HDTV video standards, thirteen kinds of testing signals recommended by the Movie and Television Industry.
