一场大型演唱会的信号传输系统设计

Design of Signal Transmission System for Scale Concerts

安全、可靠、完备的信号传输是直播节目成功的前提条件。当前,为获得更好的视听效果,大型场馆综艺晚会的节目制作中设置的机位越来越多,导演组要求应用更多更特殊的角度获取信号,信号传输的复杂度呈几何级数上升。为适应这一趋势,湖南卫视信号传输团队在直播过程中采用了大量使用无线机位、利用小型微波加光缆向转播车传输信号的解决方案,完美实现了节目团队的设计效果。

Safe, reliable and complete program signals transmission is the important precondition of a successful live TV program. At present, more cameras are placed in TV gala in large-scale venues for better audiovisual effects. Therefore, the complexity of program signals transmission system goes up by geometrical progression. To adapt to this tendency, HNTV＇s team has designed a new signals transmission solution： to use a lot of wireless cameras and to transmit signals to the outside broadcast van by small size microwave equipment and optical cable. The solution has perfectly realized the program＇s design effect.
