I need to video a conference and project the live video feed onto a projection screen.? - 150 projection screen

I use a Sony Handycam DCR-SR80 you, to be held by a video conference. I also have a projector. There are more than 150 at the conference, you need to talk about a projection of man. So my question is how to connect the camera, recorder and a projector, so can record video onto a large screen project (I have a laptop, if you are) So you help? Any help would be great! Thank you.
