TechCrunch TV has revealed how it managed to provide more than 20 hours of live CES video coverage, using backpack systems instead of a satellite truck with or special expensive (and fixed-location) video fiber circuit.

“We used a LiveU mobile package provided by our live streaming partner, Ustream. The livepack fits in a custom designed backpack. It takes a firewire input containing video and audio from a camera. We used our Panasonic HVX200a camera and some wireless microphones and a camera LED light. The livepack has 6 data modems and attempts to connect to 3 different mobile phone networks (ATT, Verizon, and Sprint). The signal is put back together by LiveU and then sent to Ustream for live streaming distribution.”
