PROBLEM TO BE SOLVED: To realize one-to-multi communication, when conducting communication among portal nodes configuring a bridge interconnecting IEEE1394 bus. SOLUTION: This processor is provided with a photodiode 170, that receives a light signal resulting from converting a signal in compliance with the IEEE1394 standards from two nodes or more into infrared-ray communication light, a demodulation/descrambling section 172 that demodulates a light receiving signal, a header extract section 174 that extracts a header added to the light receiving signal from the demodulation/descrambling section 172, a data decoding section 176, that decodes a signal in compliance with the IEEE1394 standards based on header information and a switch section 180, that selectively outputs the signal in compliance with the IEEE1394 standards to be decoded based on the header. |
