This is not "digital television" — it is a normal composite video signal for analog television converted to a digital format for transmission and then converted back to analog for display.
其主要技术的应用涉及电视视频图象模拟技术、外弹道仿真及水柱坐标处理技术、距离方位法校射模拟技术及计算处理实时性技术。
The main technologies it involves including TV video image imitate; exterior ballistic simulation, waterspout coordinate processing; range bearing spotting imitate and real-time calculating.
