摘要
当前,广播电视台内部的视频、音频非线性编辑网和数字化播出网基本上都是采用数字化IP方式,在方便使用、优化工作的同时,也带来了感染网络病毒的问题,本文主要针对广播电视台的媒体网络的病毒危害性,对如何使用媒体网关来防止病毒入侵、提高内部网络安全方面作了详细的论述。
At present,the non-linear editing network and the digital broadcast network of video/audio programs in most radio and television stations utilize digital internet protocols(IP).While such approach facilitates the usage and improves the efficiency,it also introduces the risk of network virus infections.This paper concerns the potential hazard of virus in radio and television media networks,and presents a detailed discussion on how to use the media gateway to prevent the intrusion of network virus and improve the internal network security.
