BC8110 HD H.264 or AVS Airborne Encoder

The Telairity BC8110 is a high definition (HD) video encoder designed expressly for Helicopters and other aerial vehicles used in Electronic News Gathering (ENG). It uniquely combines leading-edge compression technology (either H.264/AVC or AVS) with outstanding encode latencies as low as 150ms, achieving more than twice the compression efficiency of the older MPEG-2 standard in true real time. It combines all the features of its companion BH8110 for ground ENG vehicles in a half-rack package specially designed to fit in helicopters and fixed-wing aerial ENG vehicles. The entire unit is ruggedized and runs on 28V DC current.
