Broadcast Without Boundaries: VidiU

The Teradek VidiU is the latest consumer HDMI H.264 encoder that streams 1080p video at up to 5Mbps over dual band 802.11 a/b/g/n MIMO WiFi, Ethernet, or a 3G/4G USB cellular modem. VidiU is certified by Ustream and the new Livestream platforms, but also includes a generic RTMP interface that enables streaming to any other platform on the Web. Despite the device's compact, light weight chassis, VidiU packs a number of great features including an intuitive OLED display, built-in Li-Ion battery, mic/line input, and iOS monitoring & control via the free VidiU application.

Cut the Cable: Cube

Cube utilizes high profile H.264 compression and support resolutions up to 1080p at 5mbps over dual band 802.11 a/b/g/n MIMO WiFi or 10mbps over Ethernet. Each encoder has an intuitive OLED display for rapid configuration, and a rechargeable Li-Ion battery, which enables users to swap external power sources without powering the unit down. For the most challenging broadcast applications, Teradek also offers Bond and Link; two transmission systems with enhanced connectivity over bonded cellular, WiFi or hardwired networks.

Any Streaming Platform. Anytime. Anywhere.

Teradek Cube encoders offer everything needed to stream live high definition video directly to the Web. Both devices provide comprehensive protocol support for RTP, RTSP, RTMP, MPEG-TS, and HLS, which allows you to broadcast directly to your personal website, your Facebook page, or any content delivery network (CDN); e.g. Akamai,, or You can also choose from three capable streaming interfaces including dual band 802.11a/b/g/n MIMO WiFi, Ethernet, or a 3G/4G USB modem. This versatility ensures that you are never stuck without connectivity wherever you need to go live.

Webcast Enhancements

Cube includes additional features that enhance live webcast workflows. For example, users can monitor and control their live stream via an iPad, iPhone, or laptop at low latency simply by connecting their device directly to the encoder or to a shared access point. Additionally, the internal Li-Ion battery within Cube allows you to swap external power sources during long broadcasts without powering the unit down.

On-Board Proxies

Cube encoders also provide on-board proxy recording capabilities via an SD card slot on each unit. Each recorded file is saved as a .mov or .mp4 file.

Bond: Stream HD Video Over Multiple Cellular Networks

If you are in need of a fail-safe, broadcast quality Internet webcast, the Teradek Bond and Link gives Cube encoders maximum connection bandwidth and reliability. As a camera-top, micro cellular bonding solution, Bond gives you the option to stream from nearly anywhere over five 3G/4G modems from any cellular operator. Since Bond connects to the Cube encoder via USB, setup is extremely quick and you get to utilize all of the same great features Teradek encoders already offer, including monitoring and proxy recording.

Sputnik Server

To recombine the data packets from Bond’s modems into a cohesive video stream, your live broadcast must first be transmitted to a Sputnik server hosted on Amazon’s EC2 cloud or on your own Linux computer with a publicly addressable TCP port. Sputnik is Teradek’s free software application between Bond and your streaming destination, whether its a content delivery network or an IPTV decoder.


To monitor the status of your Bond broadcast, Teradek has introduced the Dashboard utility. Dashboard is a web application that allows you to monitor your modems’ status, bit rate, latency, and data usage in real time. 

Link: Bonded Cellular Hotspot

The Teradek Link offers web casters a whole new workflow for streaming live HD video to the Web without worrying about cellular dead zones. As a bonded V-mount cellular hotspot, Link can easily be placed in locations with optimal signal reception so camera crews can roam freely at up to 300 feet away for long periods of time. This freedom is achieved by connecting one or more Teradek encoders to Link’s a/b/g/n WiFi network. After receiving audio and video from the encoder via WiFi, Link intelligently broadcasts the feed over up to 6 aggregated 3G/4G cellular connections to a Sputnik server in the cloud or at your station. From Sputnik, your video feed is then sent to its destination.

802.11 a/b/g/n WiFi Over Cellular

Link, just like Bond, is capable of using all of the award-winning features of the Cube encoders while streaming, such as monitoring on iOS devices, on-board proxy recording, and seamless external battery swapping. Additionally, Link provides dual Ethernet jacks for hardline reliability and supports connections from any 802.11 enabled device, which means you can check your email or upload files over Link’s Internet connection while streaming your video content.
