Abstract

PURPOSE:To enable to easily execute the channel selecting operation at the time of reproduction of a VTR, by adding a circuit for deciding whether an output channel of a VTR, etc. has been received by a TV set or not, and the channel selection switch for receiving a VTR has been pushed or not. CONSTITUTION:The counter 21 which is a binary counter of 3 bits is decoded to 8 positions (PS) of A-H by the decoder 22, and the H-PS is made an exclusive PS for receiving a VTR. The output of the decoder 22 is connected to the SW group 1 where corresponding to each PS, the selective switch (SW) of 1 piece each has been provided, and its output is connected to the clock control circuit 5 and the skip control circuit 6. Also, it is preset so that a VTR can be received by the variable resistor 3 corresponding to the H-PS. When the A-PS is selected and in this case, the VTR is made a reproduction state, a broadcast wave which has been received by the A-PS disappears, the output of the synchronization deciding circuit 7 becomes an L level, the L level is input to the circuit 5, the skip operation is started, the output of the decoder 22 becomes an H level, and a reproduction picture of a VTR is received.
