FIELD: radio engineering, communication.
SUBSTANCE: invention discloses a transmitter, a transmission method, a receiver and a reception method which allow the acquisition of all selection information during multi-segment broadcasting. A relevant information generating unit 51 generates an NIT including channel selection information of a central segment of the multi-segment broadcasting and an NIT including channel selection information of non-central segments. A transmitter unit 57 transmits the NIT of the central segment as the actual NIT and the NIT of the non-central segments as the other NIT using the central segment. Such a configuration can be applied, for example, to a broadcasting unit that transmits the multi-segment broadcasting using terrestrial digital broadcast waves.
EFFECT: providing compatibility of the disclosed transmitter with existing receivers which are not equipped with means of receiving multi-segment transmission.
