SOA全台网络化节目制播体系环境下跨系统工作流程设计和服务关系(上)

Design of and Service Relationship in Cross-System Working Process in Environment of SOA Networked Program Production and Broadcasting System at Whole Station (1)

本文以电视台节目制播体系架构设计为背景,结合北京台新电视中心技术系统设计和建设实践,介绍了采用SOA模式的全台网络化制播体系架构以及此架构下跨系统工作流程的设计思路,着重从数据交换、服务关系和数据流程等多个角度对流程本质进行了分析,并通过实例对流程设计进行了详细说明。

The service-oriented architecture (SOA) is a software architecture used for system development. Combined with a practice in designing and constructing technical system of a new TV center at Beijing Television,a networked production and broadcasting architecture using SOA mode and basic design ideas for cross- system working process under this architecture are introduced,and an analysis of the essence of the process is made mainly from the angles of data exchange,service relationship and data flow. The design of working process is illustrated in detail with living examples.
