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.

-
PTZ Camera Control
Control multiple PTZ cameras—pan, tilt, or zoom, activate tally lights, set or apply presets, or use stored macros for video switching coordinated by bus buttons. Connect to up to 16 cameras.
-
Support to Build SDI/NDI Mixed System
Easily add devices or computer content compatible with NDI output (such as videos, videoconferencing streams, presentations, or computer graphics) to SDI systems. Reliable baseband switchers can also be added to your NDI system. 
-
SDI/IP Conversion and Routing
Add PTZ camera output, computer content, or other sources to SDI equipment, and freely convert between SDI and MoIP while routing video/audio from a single switcher to multiple devices. SDI/IP sources and output can be arranged side by side with the built-in multi-viewer for monitoring over MoIP.
-
2-way Transfer of Many Signals Using only LAN Cables
Two-way transfer with multiple video, audio, control, or tally systems using only one LAN cable. 
-
Excels in Many Applications
Beneficial for broadcasting, live production, corporate events, or other applications, regardless of the market.
Examples of Application
Mixed SDI/NDI Production
Video feeds with both on-site and remote performers can be sent to the switcher along with computer content. In addition to the PGM bus, provides an ample selection of Aux buses (12) that can be used to send any video back to remote talent.
SDI/IP Simulcasts
Simultaneously with SDI playout, connect to streaming sites via a MoIP stream, enabling mixed or coordinated broadcasts of both sources.
