Communication system, communication device and communication method

摘要

There are provided a communication system, a communication device and a communication method that operate with a reduced load when exchanging data streams by way of a network comprising a serial bus. A communication system according to the invention comprises a serial bus 4 for transmitting data, a magneto-optical disc device 1 and/or an optical device 2 for transmitting data to the serial bus 4 as a periodical isochronous packet and an amplifier 3 adapted to monitor the serial bus 4 for the transmission of an isochronous packet from the magneto-optical disc device 1 or the optical device 2 and start receiving the isochronous packet upon detecting the transmission of an isochronous packet that is available to it. <IMAGE>
