Start counting the number four. This operation will be explained with reference to FIGS. 5 and 7. First, a low level signal is output from the terminal (PD). Then, a pulse signal (Pl) of the no-y level is output from the terminal (01). At this time, signal line diagram c
A high level signal is supplied to 1fl through a light emitting diode (241).This signal is sent to the terminal (Ml)~
(M4) Count the number of light emitting diodes connected to the signal line 5 by inputting the data. After this, a pulse signal (P2) is output from the terminal (O2) and the number of light emitting diodes is counted in the same way. Do the same for terminal (0!1) (0'4)K. By summing the number of light emitting diodes obtained in this manner, the number of selected channels of the VTR can be determined.
