In a receiver, when a channel is registered on the channel map 15, the receiver 1 registers the channel by the unit of a physical channel, and when a channel is deleted from the channel map 15, the receiver 1 deletes the channel by the unit of a sub-channel. A common user has a tendency of watching most of a plurality of sub-channels contained in one physical channel and a tendency of not watching a portion of the plurality of sub-channels which the user does not like.
