Abstract:
1. An isochronous data transfer method realized in a variable isochronous data transfer apparatus including a variable isochronous transfer buffer (VITF), a constant isochronous transfer buffer (CITF), and an asynchronous transfer buffer (ATF), for isochronously transferring data within a predetermined time on an IEEE 1394 bus, comprising the steps of: transferring isochronous data through the CITF in an isochronous phase; transferring Available Bit Rate (ABR) data through the VITF in a variable isochronous phase; moving a portion corresponding to minimum bandwidth (MBW) in the ABR data output through the VITF and from the VITF to the CITF; and transferring the portion corresponding to the MBW through the CITF in the isochronous phase; and transferring asynchronous data through the ATF in an asynchronous phase.
