Abstract: A broadcast receiver suitable for receiving broadcast signals transferred by use of signal format of IBOC system. The broadcast receiver comprises a receiving means that receives those broadcast signals; and an information ho lding means that holds information related to channels that can be acquired by a digital signal decoding process. If information related to a channel is to be used and is held by the information holding means, then it is used.

Abstract: A broadcast receiver suitable for receiving broadcast signals transferred by use of signal format of IBOC system. The broadcast receiver comprises a channel seek instructing means that instructs a commencement of a channel se ek operation for searching for and selecting selectable channels in order of frequency; a channel seek control means that commences and controls the cha nnel seek operation in response to the instruction from the channel seek ins tructing means; and a multichannel determining means that determines whether a frequency channel being selected is providing a multichannel digital broa dcast. When the multichannel determining means determines that a frequency c hannel being selected is providing a multichannel digital broadcast, the cha nnel seek control means searches for the next subchannel in order of identif ication code before searching for the next frequency channel.
