いという欠点がある。[Problems to be Solved by the Invention] In the conventional television net cue system switching control described above, the program of the generating station is actually ended from the Q control signal superimposed on the video signal of the generating station of the net cue signal. The timing of switching to another program varies because the characteristics of the control device differ for each broadcasting station. For this reason, since the time from when the program is switched to the program from the Q control signal cannot always coincide between the generating station side and the receiving station side, the Q control signal is received and unnecessary at the switching point to the program on the generating station side. There is a disadvantage that it is unavoidable that the program is transmitted.
