[hansraj]

guys i have come across the info ... that use ieee 1394 to copy the video from the handycam ... can anyone tell me in detail or any link which throws some light on what is ieee 1394 and is it better or etc etc.

i think it is a port to tranfer files.also it is better called "infra-red"

IEEE 1394 is the standard for Firewire port. Its also known as iLink.
Have a look at the wiki @ http://en.wikipedia.org/wiki/FireWire

ieee 1394 is a firewire port which are found on imac.
A very fast external bus standard that supports data transfer rates of up to 400Mbps (in 1394a) and 800Mbps (in 1394b). Products supporting the 1394 standard go under different names, depending on the company. Apple, which originally developed the technology, uses the trademarked name FireWire. Other companies use other names, such as i.link and Lynx, to describe their 1394 products.

A single 1394 port can be used to connect up 63 external devices. In addition to its high speed, 1394 also supports isochronous data -- delivering data at a guaranteed rate. This makes it ideal for devices that need to transfer high levels of data in real-time, such as video devices.

Although extremely fast and flexible, 1394 is also expensive. Like USB, 1394 supports both Plug-and-Play and hot plugging, and also provides power to peripheral devices.

Same port different ego.
Apple - firewire (400Mbps)
Sony - iLINK (400Mbps)
IEEE - 1394a (400Mbps)
Originally developed by apple and trademarked as firewire.
Sony trademarked it as iLINK.
(IEEE): Institute of Electrical and Electronics Engineers which sets standards (and watch helpless when giant collides) called it 1394a (400Mbps), 1394b (800Mbps)
Note 1394a) supports data transfer rates of up to 400Mbps while USB2 480Mbps. Result of 1394a is far much better than USB2.(good e.g. of practical results beats theoretical value) So 1394a is preferred over USB2 for video transfer (from handycam to computer or from computer to handycam)

thanks to u all... but one doubt still remains and that is , does firewire results in faster speed only or it results in difference in quality of video too. i mean to say if i use firewire port then will the quality of the imported video improve.

well i think it should result in less drop frames only but iam not sure...?

infra-red is something totally different .. iee1394 is not called infra-red.

clear your doubt:
yes,firewire result in faster speed as well as it will improve video quality by less frame drop .
currently the best way to transfer video to pc is FIREWIRE.
