Abstract
It is an object to provide a broadcast receiving device capable of shortening the time from turning-on until display of an IP broadcast. A broadcast receiving device 1, after its start-up, automatically performs setting related to an Internet protocol (IP) including setting of an address of a DNS server and receives an IP broadcast of a specified channel by multicast communication, wherein the broadcast receiving device starts to receive the IP broadcast from an IP broadcast server 53a through an IP network 4 by specifying a multicast address corresponding to the specified channel that is stored beforehand, before completion of the setting of the address of the DNS server.
