N4 HDMI FULL NDI® Codec

Descriptions
NDI® (Network Device Interface) is an IP-based video transmission technology developed by
NewTek (Vizrt). N4 HD FULL NDI® encoder/decoder,end-to-end latency is ultra-low (less than100ms), support for HDMI video and NDI® bi-directional conversion. One unit, dual use.
It is a compact and small unit, either to a pocket or mounted on the camera equipped with standard 1/4″ screw. N4 not only converts HDMI video to NDI ® (Encoding) but also converts NDI to HDMI (Decoding). It featured with big size Tally light, powered via PoE, DC or D-Tap (camera). What’s more, it has a 3.5 mm audio headset interface, and support audio intercom (customization).
Application
- IP-based post production
- Video output to screen
- Low latency transmission
- Video conferences
Advantages
NDI encoding + decoding, one unit, dual use
- Plug-and-play operation, HDMI to NDI®, or NDI® to the screen;
● Equipped with HDMI input and output interfaces, which can be looped out on the monitor during streaming, or output HDMI signal during decoding;
● Preset 10 outputs, including 9 decoding addresses and 1 blank preset box (customizable background color), and USB extended keyboard for switching.
High quality and low latency transmission
- Encoding and decoding both support 1080p60 (HD) resolution, backward compatible with SD/HD/VESA resolution and other special resolutions;
- Ultra-low latency, end-to-end latency is less than 100ms;
- FULL NDI high-quality encoding ensures excellent image quality, and lossless audio encoding ensures high-fidelity sound quality;
- Accurate clock and intelligent algorithm ensured video frame, image and audio synchronization.
More advanced functions at your palm
- Built-in large-size Tally light to indicate PGM (program output) or PVW (pre-monitor output) status;
- Support for PoE (Power over Ethernet) and 5-18V DC input powered by USB, mobile power or camera battery;
- Equipped with 3.5mm headset interface, support voice intercom (customization).
- PTZ control with protocols of Visca/Visca over IP/Pelco (special PTZ control protocols can be customized);
●Integrated with IMS software to realize functions such as remote management and control, NDI stream management and distribution, centralized call management, and large-scale program production management; - SDK/API provided for secondary development.
