AI Technical Summary
Technical Problem
Existing methods for measuring latency in video stream distribution chains modify the video stream, degrading it and limiting measurement capabilities, particularly in production environments, and are limited to decoded streams, reducing the number of measurement points.
Method used
A method and equipment for processing video streams that insert signaling message traceability data into the stream, allowing latency measurement without degrading the stream, enabling measurements at multiple points in the distribution chain, including compressed streams.
Benefits of technology
Enables accurate and flexible latency measurement across various points in the distribution chain without modifying the video stream, supporting automated and unbiased latency determination.

Abstract
A method for processing a multimedia stream comprising a sequence of images is proposed, which includes, in a multimedia stream management unit: generating traceability metadata for an image in the image sequence; inserting the image traceability metadata into a supplementary data stream obtained by the multimedia stream management unit; and multiplexing the multimedia stream and the supplementary data stream.
