Abstract: A method of notifying a user of payment information for a pay program in a broadcast receiver is provided. The broadcast receiver includes a broadcast reception unit, which receives a broadcast signal of the pay program, a smart card, which comprises subscriber information, a conditional reception module, which compares authentication information included in the broadcast signal with the subscriber information and descrambles the broadcast signal if a user of the broadcast receiver is an authorized user, a valid information verification module, which extracts valid information from the descrambled broadcast signal, and an acoustic output unit, which notifies the user that the value of the extracted valid information is less than a predetermined critical value by using speech if the value of the extracted valid information is less than the predetermined critical value.
