IEEE1394 is a high speed serial bus like SCSI but has simple connections and hot-plugging capabilities
like USB. The interface IEEE1394 has a bandwidth of 100-400 Mbits/sec and can handle up to 63 units
on the same bus. IEEE1394 is also used in high-end digital equipment and should be marked “DV” for
Digital Video port.
