What is firewire?
Can somebody give me an overview on what firewire is and how does it differ
from USB? I have a friend who wants to use his video camera as a web cam and said he wants to use firewire. How would someone do this? Kevin |

Hello Kevin,
Firewire (Apple name) = Ilink (Sony name) = IEEE 1394 (Technical name) It's the connection you found on every DV camera Speed of native Firewire is 400 Mbps/s (exist in 800 mbps version) Faster to USB 1.0 but equivalent to USB 2.0 It can be used on PC for : Connecting DV camera Connecting Industrial 1394 camera Connecting Firewire Hard Drive Connecting Firewire webcam .... See http://www.1394ta.org/About/products..._products.html FireWire vs. USB; Apple and Intel Play Hardball : http://www.pcstats.com/articleview.cfm?articleID=1104 But I sugest your friend to buy an USB webcam because I' think it's cheaper and easier ...

"Noël" wrote in message ... One small extra thing... USB 2.0 is one way "simplex" at 400 Mbps/s and IEEE 1394 both way's "full duplex" at 400 Mbps/s As far as I am aware IEEE1394 is half-duplex i.e. bidirectional, a node may either transmit or receive at a given time, but not do both simultaneously. This is (very loosely) similar to the way USB works, which matches half-duplex best of the three usual terms, though strictly speaking is a bus with a logical star topology. I don't know the details, but I've heard there is a more modern version of 1394 in the wings with a higher data rate, which might also offer full duplex operation - perhaps someone here knows more details? Of course, in the context of webcams this is a moot point, unless someone can think of a reason to send a lot of data to a webcam! ) Phil |
