Hello all,

I have a question, might look stupid, sorry for that....
What is port IEEE1394 on laptops for and what for we use it?

Thanks

AKA Firewire. It is a 400 Mbps serial communication system that was the
forerunner of USB (USB can be though of as a Firewire-Lite but that is
probably being over generous). Although it may appear to be slower than the
480 Mbps of USB2, it is in fact faster for a number of reasons. It's full
duplex (USB is half duplex), and it can operate without much support from
the CPU (USB requires considerable CPU support). Firewire can also operate
without a host port or with several host ports (but not under Windows as
supplied). USB must have one (and only one) host port.

It is most useful for video transfer (say from a digital camcorder) and for
external hard disk drives. It can also be used to network several PCs
together, something Windows supports straight out of the box.

It has recently had a shot in the arm and IEEE1394b ports and devices are
beginning to appear. This is a 800 Mbps system, but a change in protocol
means that it is actually a bit more than twice as fast. 1394b systems are
backwardly compatible with 1394.

There are also Firewire-1600 and Firewire-3200 systems, but these are very
specialised and only work over fibre-optic links.

That is a "Firewire" port and it's used for high speed connection to
various devices. It's like USB 2.0 in many (but not all) ways. Among
the devices that commonly use this type of port are virtually all
digital camcorders, some digital still cameras, some external hard drives.

so does that mean a firewire external device will boot?

there seem to be 1394 support in the bios but no USB?/

If the BIOS supports booting from a Firewire device, then yes: you can boot
from Firewire.

Not to mention a good number of mobile phones, although Bluetooth is
probably replacing more and more this type of connection.

Hello and thanks a lot,

But i could not find a cable with both ends having the IEEE connection,
to attach one to my camera and the other one to my laptop. Is that the
way it works? I mean i dont need a capture card on my laptop if it has
the IEEE port? and is there any canlde with both ends with ieee
connection?

if you dont mind it, I am looking for more details on how should i use
that port to transfer my movies from my camcorder to my laptop..is this
the right way? what i am doing now, is i have a capture card on my pc,
and use a cable wth one end as ieee to connect to my camcorder and the
other end with a special connection (nearly like a usb but not exactly)
which connects to my capture card on pc.

Thanks

No you still need a capture card. I use an USB one for this purpose.

If your laptop has a 1394 socket, the capture card is almost certainly
implemented on the motherboard - so you don't need a separate one. Your
camera should come with some appropriate software to control data transfer
between camera and computer.

Laptops invariably have the smaller 4-pin 1394 sockets rather than the
larger 6-pin sockets used on desktop computers - so you need the appropriate
cable - probably 4-pin to 4-pin to go between your camera and your laptop.

See http://www.simplydv.co.uk/infobase/about_firewire.html for a better
explanation - or Google for IEEE1394.

My Panasonic camcorder works well with Windows Moviemaker
(included with Windows XP). It can rewind the tape as well as
transfer to or from tape.

I did need the 4-pin to 4-pin cable to use it with a laptop.
These are not real common at most retailers so you may need to have
them order it for you or buy it on-line somewhere.

Yes, you connect your camcorder to your laptop using a an IEEE 1394
(firewire) connection. [Note, not all camcorders have such connections.]

Cable are readily available. There are two connectors for this port, a
4-pin connector and a larger 6-pin connector. The signal connections
are the same, but the 6-pin connector allows the host to supply power to
the Firewire device. There are all varieties of cables (4 pins at both
ends, 6 pins at both ends and 4-to-6 pin).

You do not need a capture card to capture the camcorder output. Some
camcorders also have "pass through conversion" and will convert analog
video to firewire output (effectively, the camcorder itself is a
"capture card").

No, not correct .... well, not exactly.

Firewire (1394) is a data signal, like USB. A laptop with a 1394 port
can acquire a video stream from a digital camcorder that also has a 1394
port, but not becuase there is a capture card on the motherboard.
Rather, it is because the camcorder itself is sending the video stream
to the laptop as a computer file, already converted. That's the whole
point of a DIGITAL camcorder ... the video is stored as a digital
computer file, not as an analog signal that needs to be "captured".
