Firewire connection design

[Whatever]

Hi all,

I intend to build a firewire (ieee1394) connection beetween an ADC and my
laptop
However, i don't know anything about firewire
1 - How can i use 8 bits ADC values in a 4 pins firewire connector
2 - Is there a controler for firewire to buy or something to genereate a
clean signal

If someone had a response, it would be great

Thanks
