The Teradek Bond HDMI Live Event Bundle is an ingenious little HD video transmission system that employs up to five USB cellular modems (not included) to send high-quality H.264 files over the Internet – from anywhere with cellular coverage and to a Web-based streaming service. The key to the system is the Bond device's ability to split an encoded H.264 stream into pieces, and the system's Adaptive Internet Streaming technology, which adjusts bit rates and buffering on the fly based on changing network conditions.
The Bond HDMI Live Event Bundle starts with the Cube 250 encoder, which has an HDMI input that accepts a compatible signal from your camcorder's output. (Or from your DSLR, as long as it puts out a clean HDMI signal. Most DSLR cameras do not.) The encoder sends the encoded H.264 video to the Bond device via USB. Bond works its magic in conjunction with the 3G/4G USB cellular modems that you've attached to the device like antennae. Even with all those elements combined, this is remains a low-power, lightweight system – Bond and the Cube 250 together weigh only 13 oz.
For live-event producers and freelance camera operators, this setup means that even with mediocre network coverage, delivery of a high-definition video stream is ensured. How do these cellular streams get recombined into a usable video signal? Teradek supplies Sputnik software, which can exist either on a Linux server or in a cloud computing environment, such as Amazon EC2 or Rackspace. Sputnik puts out an MPEG-TS stream that's compatible with most H.264 IP decoders, including Teradek's Cube decoders (sold separately).
Alternatively, Sputnik can be set to send the recombined stream directly to Livestream or another web video streaming service, which presents a supremely simple way to live-stream a newsworthy event.
Note! MPEG-TS license required in order to use the generated MPEG-TS stream.
