You’ve heard of UStream? Well Google is looking to add similar functionality to their popular video site. Today and tomorrow YouTube will be testing a live streaming platform with four content partners: Howcast, Next New Networks, Rocketboom and Young Hollywood. The platform seemlessly integrates live streaming into a YouTube channel page. All they require of selected broadcasters is a webcam or external USB/FireWire camera. Easy peesy, right? A “Live Comments” module sits to the right of the live video stream; this gives viewers and broadcasters the ability to communicate with one another. Remember this is only a two-day trial only for the specified content partners; Google promises to ”evaluate rolling out the platform more broadly to our partners worldwide” at an undisclosed date. So don’t think you can broadcast live your own keyboard cat doing his thing for the world to see…yet. Click the links provided above (or scrub through the interactive embedded YouTube TV-mabob) to catch live content before time runs out.
