Help using a handycam to broadcast

[Fishgetter]

I would like to broadcast live events using Sony Handycam SR80 that I already own that has accessories like a remote mike. I need some help figuring out how to hook it to my pc/laptop. How do I know or find a firewire that will work? I ask Best Buy but their associates are just part time college kids with no answers. All help is appreciated as I'm a novice at this. Anyone using this setup? thanks
