To allow a broadcast transmission to be preformed successfully. A source device 10 reads out EDID from EDID ROMs 30a-1 to 30a-N of sink devices 30-1 to 30-N, respectively, by using information transmitting and receiving function. The source device 10 determines a transmission data format in an AV stream so as to be compatible with all of the sink devices 30-1 to 30-N, based on data format information in the EDID. The source device 10 broadcasts the AV stream based on the transmission data format determined as described above to the sink devices 30-1 to 30-N. The sink devices 30-1 to 30-N receive the AV stream broadcast from the source device 10. Since the transmission data format of the AV stream is compatible with all of the sink devices 30-1 to 30-N, all of the sink devices 30-1 to 30-N can successfully reproduce the received AV stream.
