There are several streaming sites you can use. The major streaming sites you could use are like ustream, livestream, justin.tv, twitch.tv, or own3d; however twitch.tv and own3d are usually used for streaming video games. These sites will allow you to stream a webcam in full HD, as well as voice. If you want to stream multiple webcam views, other programs (maybe a VoIP
program like Skype) you will need to set up a program called XSplit. XSplit may actually be a better alternative for you, because it will help you set up the settings for the streaming sites.
