The Broadcaster from LiveStream allows you to stream live HD video directly from any camera supporting  HDMI out. Powered by 3 AA batteries, the unit can be mounted to the camera and will stream video via Wi-Fi or a 3G or 4G USB modem.  Supporting 1080i, 720p and 480i resolutions, the Broadcaster encodes the signal in real-time using H.264 and AAC audio.  The stream can be controlled via the built-in LCD panel, through the Livestream Web based platform, or via iPhone app.
