IEEE 802.3Standard that defines wired Ethernet.See: grouper.ieee.org/groups/802/3/index.htmlIEEE 1394 (a.k.a. FireWire, I-Link)A standard for a peer-to-peer serial digital interface which can operate at 100, 200, 400or 800 Mb/s. IEEE 1394a specifies working up to 400 Mb/s, typically over copper cablesup to 4.5 meters in length with six-pin connectors. Consumerdevices use a four-pin connector.Extenders increase the maximum distance from 4.5 meters on copper cables up to about100 meters on glass optical fiber.IEEE 1394b extends both data rate and distance: up to 1.6Gb/s on shielded twisted paircable up to 4.5m, and has architecture to support 3.2Gb/s over 100m on optical fiber.Practically it can send A/V media over 100m of Cat-5 cable at 100 Mb/s. Consumersconnect DV devices over longer distances using readily available low cost cables. IEEE 1394chas a data rate to 800 Mb/s over Cat5 cable and combines 1394 and GigE on one cable.IHigh speed and low cost of IEEE 1394a and b make it popular in multimedia and digitalvideo applications. Uses include peer-to-peer connections for digital dub editing betweencamcorders, as well as interfacing VCRs, printers, PCs, TVs and digital cameras.IEEE 1394 is recognised by SMPTE and EBU as a networking technology for transport ofpacketized video and audio. Its isochronous data channel can provide guaranteed bandwidthfor frame-accurate realtime (and faster) transfers of video and audio while its asynchronousmode can carry metadata and support I/P. Both modes may be run simultaneously.See also: Asynchronous, IsochronousWebsite: www.1394ta.org105
