Using Canon7D with HDMI Connection

[sdmimedia]

I want to start live webcasting for our church. We would rather not use the webcam on the computer. Instead, I really want to use my Canon 7D. I do know that the USB connection will not show this camera as an option. I found on the web that I can use the HDMI Out on the camera and connect it through the HDMI on my Dell Latitude E6510 (PC). I want to know if anyone has been successful with this and if there is something I need to know to make this as optimum as possible.

If there is another way to use my Canon 7D as a "webcam" for live stream, let me know. Most information I am finding is for the MAC. If you have info for the PC, that would be great.
