Three in one image data control

50KM bežični prijenos (supporting longer distances)

4K high-definition image with low latency

H265/H264 video kompresija

Rich interfaces

Adaptivna retransmisija

frequency hopping

slika, podaci, 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) bežični prijenos: 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 slika visoke definicije sa malom latencijom: 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 video compression – AES encryption

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.

Modul kontinuirano detektuje status smetnji svih dostupnih kanala u realnom vremenu, and automatically selects and switches to the channel with the lowest interference in the current working channel, ensuring continuous and reliable communication.
