基于SOA的电视台编辑网络结构设计

Service-Oriented Architecture Based Design for a TV Station Editing Network

针对电视台后期编辑网络的特点,将面向服务的体系结构(SOA)的设计原则加入到了非线性编辑网络的设计中,提出了基于SOA结构的设计方案。将多媒体数据的迁移服务、转码服务、技审服务集中到了中心交换局中进行,符合SOA面向服务、子网间具有良好互操作性及松耦合性的要求。通过对多种方案进行比较,对该方案在系统可用性和系统成本方面的优势进行了详细的说明。

We introduced the SOA （Service-Oriented Architecture） into a d editing network and proposed a new SOA based design approach in view of the later period editing network of a TV station. It integrated data-transport actio and data-verification service into the Multimedia Transaction Center , esign of a nonlinear characteristics of the n, transcode service which satisfied the requirements of SOA - service orientation, interoperability and loose coupling. We compared the advantages and disadvantages among several schemes and illustrated its preponderance.
