With the development and application of video ultra-high-definition technology, the traditional universal SDI technology architecture is difficult to adapt. The variety of IP technology compatibility and flexible data exchange provides an effective solution for the entire media. With the IP architecture, software will be the future of ultra HD development. Implementing IP infrastructure and integrating IP and SDI technology architecture will be imperative.
 
The full range of products from Kiloview promotes IP streaming in existing SDI signal devices. Converting SDI to IP or from SDI to IP provides a transition between SDI and IP transport: aggregates one or more elementary streams into 10 GbE, 25 GbE or higher bandwidth segments and provides signals Buffering ensures proper time alignment while also providing a clean transition between IP streams. They can also contain codecs for bandwidth savings. Provides a way to integrate IP into SDI or SDI integration into IP.
 
To achieve high-definition digital TV IP, the available bandwidth of the network must far exceed the bit rate of the transmitted video and audio. Otherwise, if the delay or packet loss will seriously affect the user's viewing experience. With a total of 50p HD video data volume of about 1.5Gbps, 10Gigabit Ethernet can transmit up to 6 channels at the same time, so to achieve uncompressed IP video data routing and exchange, you must use 10 Gigabit Ethernet.
 
Therefore, the IP network architecture is relatively simple, the network configuration is flexible, the wiring is difficult, and easy to maintain; the IP link can simultaneously support multiple SD-SDI, HD-SDI or 3G-SDI signal mixing. The equipment based on SDI has low versatility and high price, while IP-based equipment has strong versatility, high degree of localization, and relatively low construction cost of IP system.
 
Kiloview N1/N2 NDI video encoders enable smooth and efficient video transmission in IP space, compatible with all NDI-enabled systems and devices, largely replacing industry-specific connections and transmissions (such as HDMI, SDI, etc.); The video signal is transmitted by NDI code, which can realize ultra-low delay (end-to-end delay of about 150 milliseconds for network cable connection), accurate frame video, mutual identification and communication of multiple data streams, and imported chip and H.264 video coding. Technology, combined with video dynamic noise reduction, image enhancement and other technical processing, can achieve low bit rate encoding and ensure high quality image quality.
