What hardware and software do I need for internet TV with video stream

[any ANONYMOUS forum user]

I am going to make internet TV with video stream from my studio. But I know nothing about technical requirements what I need to do.

please advise me what should I do for good quality video streaming

I know I must register my own domain and stream there, but I do not know anything except this.

1. What software I need (what you recommend)
2. What hardware I need (including cameras, speakers, microphones, video card and PC requirements)

thanks a lot in advance
