It is an object of the present invention to provide a receiver which, when receiving a digital broadcast, can shorten a time necessary for performing an initial synchronization. The receiver comprises: a front end which receives an OFDM-modulated digital broadcast and outputs modulation signals Sch 1 and of at least two channels, which modulation signals and are contained in the digital broadcast; a channel decoder which receives one modulation signal Sch 1 through an A/D converter and obtains an initial synchronism to decode the modulation signal; a channel decoder which receives the other modulation signal through an A/D converter and obtains an initial synchronism to decode the modulation signal. The channel decoders, upon obtaining initial synchronisms, will mutually output and share synchronism signals. When one channel decoder is to newly obtain an initial synchronism, such an initial synchronism can be obtained in accordance with a synchronism signal outputted from the other channel decoder which has already obtained an initial synchronism, thereby shortening a time necessary for performing initial synchronization.
