Through utilization tests or the 64QAM signal under tentative specifications, intensive works have been made to standardize digital broadcasting signal format over cable television systems. At first, we describe an indoor experiment on the adjacent interference between the 64QAM signal and 3 types of analog modulation signals so far being supposed to transmit through cable television facilities. Next, we describe field tests conducted at 2 operative facilities under allowable ranges of DU ratio.
