Three in one image data control
50KM wireless transmission (supporting longer distances)
4K high-definition image with low latency
H265/H264 video compression
Rich interfaces
Adaptive retransmission
frequency hopping
영상, 데이터, 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) 무선 전송: 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 high-definition images with low latency: 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 암호화
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.
The module continuously detects the interference status of all available channels in real-time, and automatically selects and switches to the channel with the lowest interference in the current working channel, ensuring continuous and reliable communication.
