Bidirectional high-speed digital video/audio and data interface technology adopted by the Institute of Electrical and Electronics Engineers (IEEE). Unlike other video connectivity standards, FireWire requires software programming to ensure compatibility between devices; the FireWire jack on most DVD recorders, for instance, is programmed to be compatible only when connected to a digital camcorder. FireWire connections between HDTV devices, such as a digital cable box and an HDTV recorder, are controlled by 5C DTCP copy-protection technology. FireWire is Apple Computer’s version of the IEEE 1394 interface and is now administered by a consortium that includes Apple and several other companies; sometimes referred to as i.Link (Sony’s name), DISH Wire (by Echostar), and EIA-775.
