The Teradek Vidiu is a compact video encoder and streamer.
VidiU streams over dual band MIMO WiFi, Ethernet, or via a single 3G/4G USB modem. For events that require you to be completely wireless, VidiU’s rechargeable Li-Ion battery lets you roam cable-free for up to 60 minutes.
It accepts HDMI video input and streams at resolutions up to 1080p. VidiU encodes video in real-time using H.264 compression and AAC audio at up to 5Mbps. Embedded HD audio, headphone output, and a mic/line input are supported.
