ABSTRACT:
A system comprising devices connected via a 1394 serial bus solves a problem that if omission of data packet occurs in isochronous transfer capable of high-speed data transfer, only data without the omitted data packet is sent to a transfer destination. A recording/reproduction device 101 repeatedly sends image data stored in a storage medium by the isochronous transfer, and a printer 102 receives the image data repeatedly sent by the isochronous transfer. If a data packet has been omitted in the received data, the omitted data packet is obtained from the data repeatedly sent by the isochronous transfer, thus the printer 102 can print an image based on the complete image data.
