TV-Studio-3 is our entry-level mobile live streaming system. It comes with 3 camcorders. And is has a fourth HDMI input for graphics and media files from the laptop or for remote guests via Skype.
TV-Studio-3 also has expansion jacks on the case to input 4 more camcorders via SDI (serial digital interface), so it is expandable to our top-level fully-loaded iTV-Studio-6
without returning the case to us.
