Abstract

PURPOSE: To enable new channel selection through the use of light pen, by displaying the channel number on the sereen of TV receiver and pushing on the light pen to the desired channel number.
CONSTITUTION: When the switch of the light pen 3 is closed, the channel number display instruction is given to CPU10 via the cable 14, and interface circuit 11 from the pen 3 to produce 12 the channel number. The output of the circuit 12 is added 13 with the output of the signal processing circuit 7 to feed it to CRT2. Further, when the pen 3 is pushed on the channel number, e.g., on 3, which is displayed on the screen, CPU10 selects 6 the third channel via the channel selection interface circuit 9. Thus, new channel selection can be made by using the light pen.
