Three in one image data control

50KM無線傳輸 (supporting longer distances)

4K high-definition image with low latency

H265/H264視頻壓縮

Rich interfaces

自適應重傳

frequency hopping

圖像, 數據, and control in one: one-way image transmission channel; Bidirectional data transmission channel; Unidirectional remote control channel

50KM ultra long distance (for further distance requirements, please refer to the high-power 2W module) 無線傳輸: the ultimate connection efficiency brings ultra long distance transmission, with ground to air measurements reaching 20km over the line of sight interconnection; End-to-end devices are not constrained by wire control, maintaining high degrees of freedom and mobility in space and distance

4K低延遲嘅高清圖像: Ultra high bandwidth and stream support can easily handle 4K resolution video data streams. The 200ms screen to screen low latency and delay jitter sensitivity control is good, meeting the real-time requirements of video data end-to-end

H265/H264視頻壓縮 – 自動安全與電子認證加密

HDMI+Ethernet port HDML; HDMI + AV-HDMI; SDI + AV-HDMI

The implementation of an adaptive retransmission mechanism at the bottom layer not only greatly outperforms the retransmission mechanism at the application layer in terms of efficiency and latency, but also greatly improves the performance and user experience of the link in interference environments.
