In a step S1, when the user executes a tuning operation (a service-number input operation) on an input section, the information is output to a control section. In a step S3, the control section determines whether the service number selected in the step S1 corresponds to a promotion channel. When it is determined that the service number corresponds to a promotion channel, the procedure proceeds to a step S11. In the step S11, the control section displays on the monitor a message indicating that the selected service number is not found.
