Abstract

PURPOSE: To obtain a cheap touch-system channel selection unit in the television with a recording function where a television receiver and a VTR are combined.
CONSTITUTION: When a channel is selected by channel selection button 101, specific information is taken out from digital circuit 151 during the time when address switching circuit 150 is switched to the position shown in the figure, and this information is converted to a DC voltage by D/A converter circuit. Then, tuning voltage switching circuit 153 is operated to connect prescribed tuning voltage a' to electronic tuning tuner 105, and then, a program is projected onto display device 109. When a channel is selected by channel selection button 102, another information is taken out from circuit 151 during the time when circuit 150 is switched to the opposite position, and this information is converted to a DC voltage by converter circuit 152, and circuit 153 is switched to the position opposite to the figure to connect prescribed tuning voltage b' to electronic tuning tuner 205, and then, a program can be recorded on a magnetic tape.
