ST11HPT is a miniature long range HD video data transmitter system for UAV FPV. It develops CABAC (H.264+H.265) coding&decoding technology to achieve Utra-high resolution(1080P), long distance (air to ground up to 8-12 km). The system supports two-way(data&image) communication, adjustable video resolution, bit rate output with the TPlayer software. It can realize the soft decoding with low delay. Meanwhile this SUNTOR series products have small size, light-weight, high stability and high sensitivity. It can transmit good quality and stable full-hd digital video signal under the condition of high speed moving transmission in line of sight environment.
