PURPOSE:To adjust a digital processing circuit without using a specific means by adjusting the digital signal processing circuit by remote control signals under the adjusting state and storing the adjusted data in a storage element. CONSTITUTION:An operation instruction sent from a remote control transmitter 3 is applied to a remote control signal discrimination circuit 23 through a remote control receiver 4. The circuit 23 discriminates the kinds of remote control signals A-Q and sends a signal to a control circuit corresponding to each operation. At the time of adjusting state, a switching circuit 22 is turned to the Y side and the cut-off of a color output circuit 10, the driving of the circuit 10, the vertical amplitude of a signal processing circuit 9, and the horizontal amplitude of the circuit 9 are adjusted by signals A-F, G-L, M and N, and O and P respectively. Data adjusted by the remote control signals A-P are written in the storage element 5 as the initial data of the circuit 9 by the remote control signal Q. When the switching circuit 22 is turned to the X side, the device is in the normal state and a power supply, volume, channel selection, etc. are controlled by the remote control signals A-Q. |
