The PD3-4K Air AV over IP transceiver is a digitized distributed image processing and control system based on network and nodes. In the system, the encoding nodes collect multiple AV signal sources distributed across multiple locations and transcode them into IP streams, while the decoding nodes receive and display signals on screens, enabling seamless AV sharing over the network.
Supporting H.264/H.265 encoding, the PD3-4K Air delivers visually lossless 4K@60Hz 4:4:4 video with ultra-low latency and efficient bandwidth usage over standard 1G networks. The PD3-4K-DNT Air further supports Dante audio for professional synchronized audio transmission. Breaking the limitations of the traditional centralized deployment, the PD3-4K Air supports flexible distributed deployment across floors, zones, and networks.
With an ultra-compact design, the PD3-4K Air integrates 5K output, long-distance AV transmission, signal switching, screen management, and intelligent central control, making it well-suited for fixed indoor installations such as meeting rooms, hotels and modern educational facilities—where simplicity, reliability, and visual excellence matter most.
