中国FAST射电望远镜建设,是受到世界关注的代表我国天文科学走向世界宇宙探索前沿的项目,为了配合中央电视台的直播需求以及贵州广播电视台的宣传需要,本台技术部门大胆采用先进的传输理念和现代高科技电视传输设备的应用,针对喀斯特地貌复杂环境下的巨型工程大型直播需求,设计出了高质量高安全性能的直播传输系统方案。在从2011年奠基开工以来的五年中,中央电视台多个频道利用这套系统对FAST主体工程施工中的关键节点进行了多场直播报道,取得了良好的收视效果。本系统为多路由、全方位、立体展示FAST的丰富内容,揭开“巨型天眼”的神秘面纱提供了良好的技术支持。
The construction of China’s FAST radio telescope is a project that is receiving worldwide attention and represents the frontier of cosmic exploration of astronomy and science in the world. In order to meet the direct broadcast needs of CCTV and the propaganda needs of Guizhou Radio and Television Station, our technology department boldly adopts the advanced transmission concept and modern Tech television transmission equipment applications, for the karst landscape complex environment under the huge needs of large-scale live broadcast, designed a high-quality high-security live transmission system solutions. In the five years since foundation laying started in 2011, CCTV channels have utilized this system to broadcast live broadcasts of key nodes in the construction of the main FAST project and achieved good viewing results. The system provides a good technical support for the rich content of multi-route, omni-directional and three-dimensional display of FAST, revealing the mystery of “Giant Sky Eye”.
