Hey guys, I am just wondering, how would such a thing be created? A live video stream such as www.blogtv.com or www.Ustream.com? Do you need some sort of software? If not, what can I do to do such a thing? Do you know of any articles that would show you how to do something like that in coding?
Programming a steaming video site is a massive job. There won't be one tutorial out there that will show you how to do it. Most of them use flash to stream their videos. What goes on at the server side is probably unique from site to site.
You need a server side software such as Adobe Flash Media Server or RED5, and a client side web FLV player that supports live video streaming. For the client side flash video player, you can check the RTMP Stream Plugin on playerdiy.com - http://www.playerdiy.com/configuration/addons/rtmp.html This is the tutorial - http://www.playerdiy.com/support/tutorial/customize-flash-video-player.html
Not really, if you get a script that already does it for you. Instead of re-inventing the wheel learn how to make a video site the efficient way.
