摘　　要：视频点播已越来越多的走入家庭,提出一种基于光纤入户方式实现的单家庭4终端视频点播系统的方案。通过NiosII处理器管理系统的运行,实现对硬盘视频数据与缓存间的DMA传输。最后将4路视频信息复用为1路信息送至用户终端。该方案将系统的软件设计和硬件设计集成在一片FPGA上,简化了系统,增强了系统稳定性。VOD has been used in family more and more. This paper presents a new scheme based on the fiber to home to design video-on-demand system with 4 terminals in one family. The whole system is managed by NioslI processor making the data transmitted from hard disk to the cache in DMA mode. The four channels video signals are multiplexed to one channel transmitted to ware design and hardware design on one FPGA to make the the terminal finally. This scheme integrates soft- system simple and more stable
