摘　　要：随着计算机性能的不断提高和计算机网络技术的进步,广播电视专业视音频节目的制作、播出逐渐具备了在虚拟化系统中部署的条件,可以在虚拟化平台上构建基于SMPTE ST2110系列标准的播出系统。而精确时间协议(Precision Time Protocol,PTP)时间同步在基于ST 2110系列标准的播出系统中非常关键。为此,讨论在虚拟化平台上为播出系统各虚拟机实现PTP高精度同步的工具和方法。With the continuous improvement of computer performance and the continuous progress of computer network technology,the production and broadcast of professional video and audio programs for radio and television gradually have the conditions for deployment in a virtualized system.A broadcast system based on the SMPTE ST2110 series standard can be built on a virtualized plaform.While Precision Time Protocol(PTP)time synchronization is crucial in the ST 2110 broadcast system,this article discusses the tools and methods for achieving PTP high-precision synchronization for virtual machines in the broadcast system on a virtualization platform.
