摘　　要：从延时播出系统设计原则入手设计基于"CPU+GPU+I/O"技术的延时播出系统。对延时播出流程及三种延时播出系统架构进行了设计,并对其相应架构进行了阐述,然后在延时播出系统中引入"CPU+GPU+I/O"技术,设计了延时播出系统软件功能窗口,最后总结归纳了延时播出系统的功能特点。From the delay broadcast system design principles, delay broadcasting system based ont＂CPU ＋ GPU ＋ I/O＂ technology is given. The delay broadcast workilow, the design of three delayed broadcast system architecture and the corresponding framework elaborated are introduced. Then the＂ CPU ＋ GPU ＋ I/O＂ for delay broadcast system is given, and delay broadcast system software features are designed. Ultimately delay broadcast system features are summarized.
