摘　　要：以HDV作为高清视频编码格式,采用CPU+GPU+I/O的构架,以及用千兆以太网和基于iSCSI的IP SAN作为网络结构,对如何构建适合高校教学的网络化高清非编室作了设计。以HDV为核心编码的非线性编辑系统既能满足当前仍有较大需求的标清节目制作,又能为高清节目制作做好充分地准备;CPU+GPU+I/O的构架有效利用CPU和GPU的处理能力,简化了非线性编辑系统,进一步降低了影视制作的门槛,从而有利于在高校和其他教育机构中推动影视技术教学;基于iSCSI的IP SAN的构架无论从成本上还是实施难度上,都极具竞争力,它基于成熟的以太网技术,随着万兆以太网的出现,它的应用将更为广泛。This paper discussed how to take HDV as high-definition video encoding format, and CPU ＋ GPU ＋ I/O as the system structure, and Gigabit Ethernet and iSCSI-based IP SAN as a network structure, to build an NLE network for college teaching. The non-linear editing system based on HDV codec can meet the needs of the current SD format video making, and also make full preparation for high-definition video making; CPU ＋ GPU ＋ I/O framework will make effective use of CPU and GPU＇ s processing capabilities, simplify non-linear editing systems, further reducing the threshold of film and television production, thus contributing to the universities and other educational institutions to promote the film and television technology teaching; iSCSI-based IP SAN ＇ s architecture is very competitive both in terms of cost and difficuhy of implementation, which is based on proven Ethernet technology, with the emergence of Gigabit Ethernet, it will be more widely applied.
