The NHD-140-TX is a 4 input to 4 network stream device encoder compatible with the NetworkHD™ 100 and 200 Series, an ultra low bandwidth H.264 AV over IP solution for distribution of point-to-point, one-to-many and many-to-many over a managed network. With its standards-based approach to video encoding, fast and simple system configuration and robust feature set, it provides the best value in networked video distribution. The NHD-140-TX H.264 encoder is intended for use with 100 or 200 Series H.264 decoders (sold seperately) to provide a complete end-to-end video distribution system. When used in conjunction with the NHD-000-CTL system controller complete control integration is simple. Key Features Ultra low network bandwidth compact encoder for up to 4 simultaneous HDMI inputs 4 streams over 1 Ethernet connection reduces network switch requirements Hugely scalable I/O, utilizing multicast technology to allow for very large commercial AV deployments Supports all SD and HD video formats - including interlaced content Configurable encode bandwidth and audio delay Seamlessly integrates with NetworkHD™ 100 and 200 Series decoders NetworkHD Touch™ control app for live video previews with drag and drop source selection Utilizes bandwidth-efficient H.264 encoding for visually lossless HD video distribution Features 4x HDMI inputs to 1 output via Ethernet port Plug and Play setup with quick networking configuration and auto discovery of components Live video unicast preview streams for use with NetworkHD Touch or a custom control UI Standards-based H.264/MPEG-4 AVC video compression Batch firmware update and batch settings functions offers a massive reduction on installation times
