Abstract
A broadcast receiver capable of receiving correct channel information anytime, even if a network to which the broadcast receiver is connected changes to another one, includes a storage unit and a controller. The storage unit stores a network configuration information file and channel information. The controller controls units of the broadcast receiver. Each time the broadcast receiver is activated, the controller connects to a network, acquires a network configuration information file from the connected network without simultaneously acquiring channel information therefrom, and determines whether network-identifying information described in the acquired network configuration information file is different from network-identifying information the network configuration information file stored in the storage unit. If the network names differ, the controller erases the stored channel information.
