【摘要】 本文针对广播电视领域的需求，分析得出了硬盘播出网络系统的设计原则和设计规划，选择了MPEG-2作为系统的视频图像压缩标准，采用并扩充了SONYRS422通信标准和外部系统通信，并通过对系统中上载工作站、编辑工作站、审片工作站、播出工作站和数据库服务器功能和模块实现的阐述，详细讨论了硬盘播出网络系统的整体设计和模块实现。并在实际应用中得以印证。在电视技术从模拟向数字过渡，从单机处理向网络发展的趋势下，硬盘播出系统必将成为新一代电视自动播出系统的核心和发展趋势，并将最后成为全硬盘播出系统。 在本文最后，又阐述了硬盘播出网络新的实现方法和硬盘播出网络值得改进的地方，为硬盘播出网络的发展和扩充指明了方向。更多还原

【Abstract】 In answering to the demand of the television-broadcasting field, this article presents through enormous analysis the designing principles and designing schemes for the Hard-disc Broadcasting Network System. It adopts Mpeg-2 as the video compression standard and chooses Sony RS422 communication protocol to communicate with outer systems. The overall designing and model realization of the Hard-disc Broadcasting Network System are explosively discussed by the elaboration of the function and application of upload station, edition station, audition station, broadcasting station and data-base server, and they are also verified in practice.Under the trend of television technology’s transition from analogy to digital, from single computer to network, the hard-disc broadcasting system is bound to be the nucleus of the new generation of automatic television broadcasting system, and ultimately, to be the broadcasting system totally based on the hard-disc.Also in the article, the new way to realize the hard-disc broadcasting network and some shortcomings in it are offered, and it’s development in future is pointed out as well.更多还原
