摘要 目前,数字化制作、数字化播出都是采用数字化IP传输,内外网间一般都加有一道“媒体网关”来作为防毒隔离墙,有效地解决了感染网络病毒的问题。但在方便使用的同时,也带来了传输速度变慢的问题,本文主要分析加入媒体网关所带来的传输速度问题,揭示了在实际使用“上传”的速度明显快于使用“下载”的速度,并提出正确的使用“上传”方法可获得最高传输速度的结论。 Nowadays,the digital development and broadcast of audio and video programs are mostly utilizing IP transmission.A“media gateway”is usually inserted between the internal and external networks as the anti-virus wall,which effectively prevents network virus infection.However,while this approach provides convenience for users,it also comes with the cost of reduced transmission speed.This article presents an analysis of the transmission speed reduction issue caused by the insertion of media gateways.It points out the fact that in practice the speed of“upload”is significantly higher than that of“download”.Moreover,it is concluded that the highest transmission speed could be achieved by utilizing the correct uploading approach.
