Color me impressed:
SlingStudio is the integrated solution for creating and sharing professional-quality content. Connect all of your video sources – including professional cameras and smartphones – to SlingStudio’s video-grade Wi-Fi network for synchronizing and broadcasting live video. SlingStudio’s portability and robust wireless technology allow you to monitor, record, switch, edit and live-broadcast your multi-camera production without compromising video quality.
The true power comes with the SlingStudio Console app for iPad:
Broadcast live and wow your viewers on Facebook and YouTube with cool transitions and camera angles, including picture-in-picture and a quad view.
I love it when technology can be used to easily orchestrate this, especially at the price tag of $999.
