Design and Development of GPS Positioning System for Mobile Live Broadcasting

厦门广播电视集团的技术研发团队,充分利用电信运营商的GPRS网络和单位现有的技术设备资源以及数传电台技术,自主设计和开发了一套专用数据传输网络和移动直播GPS定位系统。该系统在大型体育赛事移动直播中,实现了路面转播车、摩托车与航拍直升机的快速实时定位。该系统定位速度快、精度高,具有较高的稳定性与可靠性,为导演的指挥调度与直升机的精准航拍提供了"千里眼"。同时,在电视直播过程中,通过播放系统记录的各种拍摄技术装备在整个比赛线路中的实时行进轨迹,使观众在观看体育赛事直播时有一种身临其境的真实感受。

Xiamen Media Group makes full use of the telecom operators＇ GPRS network, the existing equipment and digital radio technology to independently develop a set of special data transmission network and GPS positioning system for mobile live broadcasting. The system achieves a rapid real-time positioning of the OB vans, motorcycles and aerial helicopters in the mobile live broadcasting of major sports events. The positioning system has advantages of high speed and high precision, as well as high stability and high reliability. Thus, the system is as a ＂telescope＂ for the director to command and for the helicopter to aerial photograph accurately. During the live broadcasting process, through the shooting equipment real-time tracks recorded by the playback system, ordinances have immersive feelings while watching sports events.
