Abstract

A digital broadcast receiver includes: a receiver that receives a broadcast signal of a physical channel in digital broadcasting; a current position detector that detects a current position; a current region determiner that determines, as a current region, a region to which the current position belongs; a receivability determiner that controls the receiver to determine whether the broadcast signal of the physical channel can be received; a storage unit that stores receivable area information indicating a receivable area where the broadcast signal of the physical channel can be received; and an updating unit that, when the receivability determiner determines that the broadcast signal can be received, obtains, out of the stored receivable area information, receivable area information for the current region indicating a receivable area in the current region, and performs an update process to update the receivable area information for the current region based on the current position.
