摘　　要：OSD系统是人机交互的桥梁,为满足市场需求及迎合当前高清视频发展趋势,应用一种自定义OSD界面布局方法和一种改进型二步索引算法,并对透明度混叠算法进行了变换及硬件实现,以软硬件协同的方式实现自定义OSD功能,具有界面控制灵活及低硬件资源消耗等特点。本设计通过以Xilinx公司XC7K325T-2FFG900为核心芯片的Kintex7 FPGA开发板进行了验证,结果表明该设计方案具有可行性。The OSD system is the interactive bridge of the user and display terminal. So in order to meet market demand and the current high-definition video developmental trends,a custom interface layout method and a two-step-index algorithm for OSD are applied, and the alpha overlay algorithm is converted to make it suitable for FPGA hardware implementation. The design achieves custom OSD function in a software-hardware co-operating way, which has the features like flexible to control and low re- source consumption. Simulation is done on Xilinx＇s Kintex7 FPGA development board,in which the core-chip is XC7K325T- 2FFG900. The result proves that the design is available.
