HVS-NIF for NDI Connectivity 

HVS-NIF interface cards provide NDI High Bandwidth connectivity for high-quality, low-latency video transmission and NDI HX for low bit rate transmission. The cards make it easy to build a mixed baseband/IP system you can use to exchange video and audio over a network with other NDI equipment. This is extremely effective for live video production -whether you are shooting remotely or enjoying easy streaming from computers connected via NDI.
