System and method for preserving metadata timing in a video processing node

Abstract

A system and method preserve the temporal accuracy of metadata in a flow comprising multimedia frames by applying an original flow containing original metadata to a processing environment comprising one or more components that implement a multimedia workflow to produce a processed flow. The system and method retain the original metadata before applying the original Flow to the processing environment, without altering the original Flow. The system and method generate original correlation data comprising original timing information and frame-specific fingerprints associated with the original Flow. The system and method also generate processed correlation data comprising processed timing information and frame-specific fingerprints associated with the processed Flow before determining a latency based on the original correlation data and the processed correlation data. The system and method reinsert the original flow metadata into the processed Flow based on the determined Latency.
