When a service or device sees a query for any These multicast queries are sent to a multicast address and thus, no single device is

Subnet, which then use the information in that message to update their own caches. This multicast is seen by all NDI receiving machines on the The target machine then multicasts a message that This service sends an IP multicast message To create the zeroconfiguration environment for discovery. Some cases where it is important to know how this works to properly configure networksĪs default, NDI utilizes mDNS (multicast Domain Name System) 1 While this is a typical function on almost all networks, there are When you start an application that sends NDI, the devices that can receive NDI becomeĪware instantaneously. NDI resolves host names to IP addresses over the LAN and does so automatically. Support video and are able to discover receiving applications that are looking for video. Sending and receiving video streams across an IP network requires applications that
Infrastructure or costly new high-speed network infrastructures. Pipeline without negating existing investments in SDI and HDMI cameras and Makes it possible to transition facilities to an incredibly versatile IP video production NDI’s superb performance over standard GigE networks Protocol also includes tools that implement video access rights, grouping, bi-directional Its encoding algorithm is resolution and frame-rate independent supportingĤK resolutions and beyond along with 16 channels and more of floating-point audio. NDI operates bi-directionally over a LAN with many video streams on a sharedĬonnection. NDI can benefit any network-connected videoĭevice, including video mixers, graphics systems, capture cards, and many other NDI allows multiple video systems to identify and communicate with one another over IPĪnd to encode, transmit, and receive many streams of high-quality, low latency, frameaccurate video and audio in real time. Protocol (IP), and that this vision will largely supplant current industry-specificĬonnection formats like HDMI, SDI, etc., in the production pipeline. The video industry is one in which video is transferred easily and efficiently via Internet Products to share video across a local area network (LAN). NDI is a royalty-free protocol developed by NewTek to enable video-compatible
