Live broadcasting

I am working on one project and need help related to this. Please bid if you are experience and done this before. I want to do something like tv broadcasting. I have two site, in one site say A, users will upload live video directly from their cams. So there will be multiple videous uploaded live from cam at a time. All this video will be viewed by one admin user in the same site or on other site. Now here admin will choose one video from many live videos going on. This choosen video will get displayed on other particular site say B. admin can change the display of live video which should get reflected on the other site immediately. You need to help me out, how can I do this thing. Only bid if you have done this before. Write "EXP" in your bid and also send me your sample work that you have done before. Note that you don't have to code whole thing I just need help, so bid accordingly.
