                        电视视频网络存储常见方式和技术结构

                        时间:2018-12-13 09:47作者:茹国钰
                        本文导读:这是一篇关于电视视频网络存储常见方式和技术结构的文章,广播电视行业的不断建设和发展,视频节目的核心生产结构电视台必须要根据节目的生产需要进行存储技术上的改革和创新。目前电视视频节目的数量呈现逐年上升的趋势。

                          摘    要: 互联网信息技术的高度发展促进了计算机技术在各领域中的使用和普及。在广播电视行业中,随着信息化网络技术的应用使得广播电视相关工作的工作效率显着提升。电视台的主要工作内容就是参与节目制作以及播放,需要同时对多个节目频道进行调节,在调节过程中不可避免地要涉及到对多种信号的切换和传输,其中数据的传输和存储问题是影响电视台节目播出效果的关键。本文以视频网络存储技术为核心,对电视台视频网络节目播出过程中需要使用的几种典型存储技术进行分析,为视频网络存储工作的高效化提供新的思路。

                          (四)不同存储方式的选择

                          离线、在线以及近线存储方式是当前电视台视频网络中使用频率最高的三种存储方式,在存储方式最终决定上要充分考虑实际存储需求,针对使用频率较高的视频应当存储在局域网中,针对使用频率较低的视频可以将其存储在光盘系统中并对光盘进行编号处理,针对比较珍贵的视频资源应当综合在线存储和离线存储两种存储方式,这样能够最大限度地减少资源损坏或者丢失所造成的损失。现阶段由于电视台使用者的需求呈现出多样化的趋势,因此视频网络资源的存储多采用近线存储的方式,从而满足视频存储活动的灵活性需求。
