Near real-time

The term near real-time pertains to the delay introduced, by automated data processing or network transmission, between the occurrence of an event and the availability of the processed data, e.g., for display or feedback and control purposes. For example, a near-real-time display depicts an event or situation as it existed at the current time less the processing time.

The distinction between near real-time and real-time varies and the delay is dependent on the type and speed of the processor] and [[transmission.
