Method of transferring image data using a IEEE 1394 bus

摘要

A method of transferring image data between an initiator device and a target device using a IEEE 1394 standard bus combines management functions, command functions, and isochronous data transfer to achieve the transfer of image data. It comprises the step of reading a target configuration using IEEE 1394 reads of a read only memory space (block 14). As part of the management function, a modified asynchronous data transfer protocol is used to establish a connection between the initiator and the target (block 16). Next, command functions are employed to begin a job to transfer image data over an isochronous channel (block 20). Asynchronous data transfer is also used to exchange printer job language commands to end a job (block 30).
