As for capture and encoding, I'd recommend taking a look at the options available from TeraDek (excellent, wireless solution for capturing camera footage and streaming it to the internet) and Blackmagic Designs.

Another option available is Contour's Cerevo LiveShell. Furthermore Livestream will ship the Livestream broadcaster by May 31, 2012.
