NetworkHD™ 400 Series 4K AV over IP JPEG-2000 Decoder


WyreStorm brings stunning 4K HDR video, 4K/2K auto-scaling, multi-channel audio and audio matrixing to IP with the NetworkHD 400 Series' NHD-400-RX AVoIP decoder. Used in conjunction with an NHD-400-TX encoder, the NHD-400-RX seamlessly handles mixed resolution sources, content and display devices for matrix and video wall functionality up to 16x16 with image rotation and bezel compensation.

Featuring incredibly low latency, the 400 Series is the ideal AV over IP solution for systems where high quality and low latency are key requirements, making it perfect for both residential and commercial applications.
