一种新的面向应用的媒资系统设计

Design of a New Application-type MAM System

面对高清以及即将来临的3D时代,海量数据爆炸式增长对媒体数据有效管理与再利用的进一步需求,以及全媒体新形势下对时效性和播出安全的新要求,本文针对省级电视台当今电视节目结构和形态的主要特征,提出了一种新的媒体资产管理系统的设计思路。新系统在架构上将媒体资产管理系统分为中心媒资和播出媒资两个部分,其中,中心媒资的功能以资料存储与再利用为主,为节目生产提供服务,播出媒资的功能涵括外购节目再加工、重播节目归档、待播节目存储扩充等。新的设计思路在提升系统的安全级别、提高使用效率和节目送播时效方面效果显著。

With the advent of HD era and coming of 3D, media data will present a new explosive growth. In the situation that traditional media data sharing demand in all kinds of new media platforms grows fast, how to manage orderly and effi ciently and to make good use of these media resources and how to deal with new challenge that safety broadcasting brings are new tasks that the radio & TV industry faces. Featuring effi ciency, effectiveness and security, the new MAM system design thought in this paper has solved the above problem well from the technical stratifi cation. We hope that this article will be a reference for the industry to promote development of MAM system technology.
