WyreStorm NHD-100-TX NetworkHD™ 100 Series AV over IP H.264 Encoder


The NHD-100-TX is the source device encoder for the NetworkHD 100 Series, an ultra low bandwidth H.264 AV over IP solution for distribution of point-to-point, one-to-many and many-to-many AV distribution over a managed network. With its standards-based approach to video encoding, simple system configuration and robust feature set, it provides the best value in networked video distribution.

The NHD-100-TX H.264 encoder is intended for use with an NHD-100-RX H.264 decoder (sold separately) to provide a complete end-to-end video distribution system. It is also compatible with the NHD-000-CTL system controller, NHD-220-RX multiview decoder.




Powered by H.264 encoding for a high quality, low bandwidth AVoIP solution, the cross-compatible NetworkHD 100 and 200 Series modular system architecture removes the limitations of traditional fixed platform matrix systems, whilst offering significant cost savings for large scale deployments.


Dynamic video processing seamlessly converts and matches source video content from each decoder to connected displays, removing video resolution and timing incompatibilities that might otherwise exist for reliable and easily manageable multi-display systems.


In addition to HDMI streaming over an IP Network, the 100 Series sends RS-232 control signals to a source or display and CEC control commands to a display device for single control signal deployment without the need for additional equipment.


WyreStorm’s QuickSync technology offers virtually instantaneous, seamless source switching free of glitches or tears between video streams for an enhanced user experience worthy of any professional video distribution installation.
