Title: Broadcast receiving device

Abstract: A broadcast receiving device includes a card slot, a fan, a temperature sensor, a memory component and a control unit. The card slot accepts an IC card. The fan rotates to cool the IC card. The temperature sensor measures a first temperature. The memory component stores correlation information indicating a correlation between the first temperature and a second temperature of the IC card. The control unit acquires the second temperature based on the first temperature and the correlation information. The control unit determines if the second temperature exceeds a predetermined temperature. The control unit switches from a first output mode, in which an audio-video signal is outputted via the IC card, to a second output mode, in which the audio-video signal is outputted by bypassing the IC card, when the control unit determines that the second temperature exceeds the predetermined temperature.
