Design and Implementation of Near-Line Media Storage Solution for Media Asset System

媒资系统作为电视台重要资产的保存和积累中心,在电视台日常运营中发挥着重要作用。随着高清、超高清电视技术的发展,视频码率的提升对于存储性能和容量的需求成倍增长。电视台需要不断投入大量的资金购置新的近线存储体,用于收集、整理、存储和再利用有价值的资料,以实现全台业务在媒资系统协同下的生产调度。蓝光光盘库以其长寿命、高安全、低功耗等特性,适用于存放不经常被修改的数据,成为数据备份的第一选择,也成为媒资近线存储体的首选。针对宁夏广播电视台现有存储系统的问题,介绍宁夏广播电视台媒资近线存储系统技术选型与设计,详细阐述媒资近线存储系统的实现与部署过程。

As the center for the preservation and accumulation of important assets of TV stations,media assets system plays an important role in the daily operation of TV stations.With the development of high-definition and ultra-high definition TV technology,the demand for storage performance and capacity has increased exponentially with the improvement of video bit rate.TV stations need to invest a lot of money to purchase new near-line storage for collecting,sorting,storing and reusing valuable data,so as to realize the production scheduling of the whole TV business under the cooperation of the media asset system.Blu-ray disc library with its long life,high security,low power consumption and other characteristics,suitable for storing data that is not often modified,become the first choice for data backup,but also become the first choice for media assets near line storage.Aiming at the problems of the existing storage system of Ningxia radio and television station,this paper mainly introduces the technology selection and design of Ningxia radio and television station’s media assets near line storage system,and elaborates the realization and deployment process of the media assets near line storage system in detail.
