Does my Macbook display port support video input? I have been reading through all these resources here and here . But, I don't have my answer. 

My question is simply, can the display port on a Mac take video input source?

More Details:  I have 


Macbook Pro Model 6,2 (Mid 2010) that has a Display Port
A camcorder that has HDMI output and NO firewire outputs. 
A HDMI to Display port adapter.


I want to know if it's possible to use my camcorder like a webcam i.e capture live video for the purpose of streaming. As a primary test, I should be able to connect the camcorder and do a capture using iMovie. 

Would this be possible? I am pretty sure input through USB won't work. And from what I have seen there is no easy way to convert the HDMI video stream into firewire. So, any suggestions?
No, the display port on your macbook pro is output only.

You may be able to use your camcorder as a webcam if it is capable of streaming video over USB or Firewire, though.
