I'm preparing to video stream some kids football games (must be streamed live). Looking for advice on the following, or links if these topics have already been addressed:

- Best way to overlay score and logos on screen in real time? Any good software?

- Ability to insert commercials on the fly? We're streaming live.

- Looking to use the RCA output on the camera to a Firewire adapter, then into a laptop for encoding and streaming out to server. Is this the best setup? Any suggestions?
Can't use an IP camera setup as we require a camera man to follow the action and control zoom etc, an IP cam would be too slow. We're planning on using a traditional video cam.

Thanks for much for the input.
