发明名称 Digital broadcast reception apparatus
摘要 There is provided a digital broadcasting receiver capable of reducing the occurrence of situations where a charge for purchase is forced to be paid, although a purchased pay program cannot be viewed due to worsened weather, power failure, or the like. When a channel is turned in to a pay per view (PPV) program, a part of the program can be viewed free of charge in a preview period. When a user performs a purchase operation in an attempt to purchase the program, a digital broadcasting receiver 30 does not immediately perform purchase processing but waits until the preview period is almost terminated, and performs the purchase processing for an IC card 21A only when the receiving condition is within an allowable range at this time point. On the other hand, it does not perform purchase processing when the receiving condition is not within the allowable range.
