<p>A data receiving device comprising receiving means for receiving a cycle timer packet, an isochronous-type packet and an asynchronous-type packet from an external device, isochronous-type packets being transmitted after said cycle timer packet and before asynchronous-type packets, said asynchronous-type packets being transmitted in a period from the end of transmission of said isochronous-type packets until a next cycle timer packet is transmitted, a cycle timer for outputting time information, means for extracting revising information for revising said cycle timer from said received cycle timer packet, means for revising said time information of said cycle timer according to said extracted revising information, storage means for temporarily storing said isochronous-type packet, means for extracting time information added to said isochronous-type packet, means for comparing said extracted time information with time information of said cycle timer and means for retrieving said isochronous-type packet from said storage means when said extracted time information corresponds to time information of said cycle timer.</p> |
