When building a conventional vi 蜘 al system at a relay spot , various task exists compa 正ed to the operation at the head omce , such as equipment procurement cost , spot preparation time, work environment , etc . Thereupon , to solve these tasks, TV Asahi developed and put to practical use on live broadcast " The VANC system ( Vertical ANCillary inserter ) " which interlocks real timc to the head o 伍 ce virtual system with the image data transmitted丘om the relay spot t血at has superimposed
