The network must support multiple video, audio, and data streams in a reliable, synchronized manner without disruption. When delay, packet loss, and jitter reach thresholds where the video is impacted visually, the usefulness of that video drops to zero. It is important to understand the complexities of video in IP data networks to mitigate these factors. Networks that are designed to move NDI video streams should be thought of as being primarily utilized for video. IP networks are, by their very nature, “best effort delivery” systems and were originally developed for the transport of data. By contrast to video, data services can function happily with packet retransmissions, lost packets, and even packets arriving out of order. Video streams, while still composed of data, are much more rigid in their requirements. With the use of modern networking equipment and proper configuration, video can move across networks whilst still obtaining low latency, frame accuracy, and high-quality requirements necessary for live video production. --- # Agent Instructions This documentation is published with GitBook.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://docs.ndi.video/all/getting-started/white-paper/getting-video-across-the-network.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
