摘要
新闻的时效性是新闻报道的首要因素,由于新闻发生时间和地点的不确定性,特别是突发的公共事件需要在最快时间将现场画面传回电视中心,需要有一套高灵活性的传输设备以适用于应急新闻采集及移动状态下的直播。DTNG(Digital Terres-trial News Gather)技术目前已成功应用于F1赛事等专业领域,提出了一种基于该技术的DTNG网络的系统构建,并给出该系统的若干实际应用案例。
Time lag is very important for news report. Due to the uncertain of time and position, a flexible transmission system is needed to translate the living video to TV studio. DSNG （Digital Satellite News Gather） system based on satellite is widely used. But DSNG system is very difficult to use in mobile and urban environment. DTNG （Digital Terrestrial News Gather） technology is already used in F1 game. A kind of DTNG network is intrndueed in this paper, and applications of this system is also given as examples.
