In addition, the relay driver 8 is controlled based on the on / off time data stored in the first data memory 19 and the time data generated by the timer 3 to perform the on / off operation of the television receiver. .

In addition, the OSD generator 20 includes a register 21 for storing OSD data indicating the magnification and position of the OSD output from the controller 15, and the address data and color data stored by the controller 15. On the basis of the above, the predetermined character data is output from the character generation ROM 24 to be described later, and the video RAM 22 for controlling the color of the OSD output by controlling the output buffer 26 is stored. A character generating ROM (Character ROM) 24, a shift register 25 for sequentially outputting character data output from the character generating ROM 24 in accordance with a clock signal from an OSD control section 23 to be described later; OSD control unit for controlling the data output timing of the video RAM 22 and the shift register 25 based on the OSD data stored in the register 21, the OSD clock (OSD CLK) and the horizontal / vertical synchronization signals (H, V). 23 and the above ratio O output by the R.
