随着湖南广电近年来高清化网络化改造的深入,原有传输系统越来越不能适应新的系统和理念,急需改造。新的传输系统从提高传输质量出发,将原来的传输基带信号转变为传输ASI流信号;着眼未来,编高码率源信号,重点保障有线网、地面数字电视、直播星平台信号,转码为新媒体等渠道提供低码率信号;对接新媒体平台,为迎接全媒体时代搭建新型传输平台系统。
With Hunan Radio and Television in recent years, the network of high-definition transformation depth, the original transmission system more and more unable to adapt to new systems and concepts, the urgent need to transform. The new transmission system aims to improve the transmission quality and transform the original transmission baseband signal into a transmission ASI stream signal. In the future, the high-bit-rate source signal is coded to focus on the wired network, the terrestrial digital television and the live broadcast satellite platform signal, and the transcoding is New media and other channels to provide low bit rate signals; docking new media platform, to meet the all-media era to build a new transmission platform system.
