A broadcast receiving device (100) comprising: a memory unit (1342-1344) for storing a receivable channel information; a determination-information acquiring unit (135b-135d) for acquiring determination information to identify a predetermined transmission condition of the transmission path; a determining unit (135e) for determining whether the transmission condition has varied, based on the determination information acquired by the determination-information acquiring unit; a detecting unit (135f) for detecting a channel of broadcasting signals which are receivable, by conducting an automatic scanning when the determining unit determines that the transmission condition of the transmission path has varied; and a renewing unit (135g) for renewing the channel information stored in the channel memory unit (234a), based on a detected result obtained by the detecting unit (135f). |
