Generating live video stream for the web

Hi,
  have you got any idea of how to generate live video stream for showing in
a web page? I was thinking of an .asx file that could be viewed with Media
Player.
 I am currently capturing live images from my web cam and sending them 1 per
second to a server via FTP, where the user can connect via HTTP and see my
images, but I would like to offer the option of live video to the ones who
have a good Internet connection.

Any sample code, URL link or advice would be greatly appreciated,
