主干系统项目组北京台新电视中心制播网络系统【【跨系统工作流程和服务关系说明书】】制播网络主干系统项目组主干系统项目组-I-文档修改记录序号修改时间内容修改描述12007-1-17本次修改根据2007-1-10和2007-1-11的结果，完善文档描述。本次有较大修改的内容有两部分：1．从前的转码转到临时目录，本次修改后，转码如果满足条件，可直接转到目标路径，可节约一次迁移操作。2．制作系统相关部分，从前未考虑深度和包装网，本次按照深度网和主干系统互联会议纪要和包装网部分特性修改。深度网提供的素材/节目都是IMX格式。深度网部署客户端以后，可以使用\\主机名\目录方式直接访问，包装网由于结构复杂，可能会使用FTP访问，包装网格式未确认，由于转码不支持FTP的访问，所以进出媒资时，步骤会多一步，由于在工作流中增加了判断，包装网不是FTP方式，流程也能正常运行。文档描述的前提基于以下几个方面：1．媒资系统归档的资料都使用MXFOP1a封装。2．除深度制作网和包装制作网外，其他系统都使用MPEG2I帧作为系统间文件交互标准，能支持MPEG2I帧直接编辑。3．播出格式的节目使用MXFOP1a封装，编码格式为MPEG2IBP12M，且该格式文件都在各应用系统内部合成。4．在调用各系统素材入库接口时，接口元数据含有本次入库命令后的文件处理方式（迁移，转码，整理）。5．流程中产生的中间数据对应用系统是透明的，由平台按照策略进行清理。22007-1-251．流程开始结束规则，流程从申请者开始，到通知数据拥有者结束2．迁移中不考虑FTP的情况，认为存储无论迁移转码都主干系统项目组-II-能直接访问。取消，系统之间文件传送时，可能需要的中间操作。3．修改页面和标签32007-2-11.增加共享演播室制作版本归档流程2.增加值作系统演播到媒资的备播3.修改制作系统归档，增加对演播备播的判断4.修改制作系统到演播室节目准备流程，制作系统仅提供MPEG2编码格式素材到演播共享系统42007-2-91.增加共享演播室[制作→演播]素材准备关于低码率的处理原则；增加媒资节目备播版和节目制作版归档后的低码率文件由节目制作版生成。2.取消从前[制作→媒资]演播节目备播流程，将该流程和[制作→媒资]节目备播合并3.增加每个流程的接口关系表，对该流程使用的接口和参考文档给出说明52007-2-131．统一迁移/转码描述2．增加对流程图的修改62007-2-251．修改[制作→媒资]节目归档、[演播→媒资]节目归档、[演播→媒资]节目备播的流程描述。2．统一流程文字描述和流程图72007-3-131．检查图中迁移转码标识2．增加[制作→演播]串联单传送82007-5-111．修改[制作→媒资]为[制作→总编室]节目备播流程2修改[演播→媒资]为[演播→总编室]节目备播流程92007-7-21、李扬整理第一版，颜涛审核修改2、删除了[制作→收录]收录任务约传3、删除了[媒资→收录]收录任务约传4、删除了[制作→媒资]节目代码申请5、增加了各流程对音频的转码控制6、修改[总编室→播出]节目文件送播为拉模式7、调整[制作→总编室]节目备播，[演播→总编室]节目备播，增加合成以后的技术审查，并在入备播库以后生成低码流8、[制作→演播]素材准备在制作域需要在合成后完成技术审查主干系统项目组-III-目录第1节服务类型分类················································································11.1.1查询类服务·················································································11.1.2执行类服务·················································································31.1.3消息类服务·················································································31.1.4入出库类服务··············································································41.1.5管理类服务·················································································5第2节业务流程描述················································································61.2.1流程描述基础··············································································61.2.1.1流程命名方式·····································································61.2.1.2文件迁移转码传送模式·························································61.2.1.3流程开始结束原则·······························································61.2.1.4低码率文件处理方式····························································71.2.1.5MD5码使用范围··································································81.2.1.6媒体文件格式与转码原则······················································81.2.2流程详细说明··············································································91.2.2.1[收录→制作]素材传送·························································91.2.2.2[收录→媒资]素材传送························································101.2.2.3[制作→总编室]节目备播·····················································111.2.2.4[制作→媒资]节目归档························································131.2.2.5[制作→媒资]素材迁移························································141.2.2.6[媒资→制作]素材回迁························································151.2.2.7[制作→制作]素材调用························································161.2.2.8[制作→演播]素材准备························································171.2.2.9[制作→演播]串联单传送·····················································181.2.2.10[演播→总编室]节目备播···················································191.2.2.11[演播→媒资]节目归档······················································201.2.2.12[演播→制作]节目回采······················································221.2.2.13[媒资→制作]资料调用······················································231.2.2.14[制作→媒资]素材挑选······················································241.2.2.15[总编室→播出]节目/字幕单送播········································251.2.2.16[总编室→播出]节目文件送播·············································26主干系统项目组-1-第1节服务类型分类北京台新电视中心制播网络系统基于SOA架构建立，各个子系统之间接口都按照协议通过业务支撑平台通信。业务支撑平台提供五个原生的服务ServiceRegister，ServiceUnRegister，ServiceLookup，ServiceInvoke，ServiceCallback，这五个服务可以直接调用，其他的服务除异步回调服务外都通过ServiceInvoke转发实现，异步回调服务通过ServiceCallback转发实现。本节按照服务的功能性质将北京台新电视中心制播网络中各系统的所有服务分为以下几个大类。1.1.1查询类服务该类服务用于供其他系统调用，查询相关系统信息。具体服务含义请参见各子系统接口规范，下表按照各系统分别列举出该系统的查询类服务。序号子系统名称服务名称1收录网络系统查询约传任务：INGSTaskQuery2查询收录设备：INGSDataQueryDevice3查询收录通道：INGSDataQueryChannel4查询入库策略：INGSDataQueryImportPlan5查询信号源信息：INGSDataQuerySiganlInfo6查询任务类型信息：INGSDataQueryTaskInfo7查询模板类型信息：INGSDataQueryTempletInfo8查询收录素材信息：INGSDataQueryMaterialInfo9制作网络系统稿件查询：PDSNewsQueryProfile10串联单查询：PDSNewsQueryListProfile11串联单内容查询：PDSNewsQueryListContents12素材库查询：PDSNLEQueryClipInfo13演播共享网络系统节目信息查询：STOSQueryPGMInfo14串联单信息查询：STOSQueryListInfo主干系统项目组-2-15设备信息查询：STOSQueryDeviceInfo16设备使用历史记录查询：STOSQueryDeviceHistory17自动播出网络系统播后统计信息查询：ATMSQueryStatistic18节目单查询：ATMSQueryPGList19播出素材查询：ATMSQueryPG20总编室编播网络系统查询选题计划申请处理进度：QueryApplyProgress21周节目计划查询：QueryWeekProgramPlanBill22日节目单查询：QueryPerDateProgramBill23节目代码查询：CHEditorProgramCodeQuery24广告编播网络系统广告单查询：ADSQueryList25素材查询：ADSQuer
