ITU-R BS.2125-1 PDF

This Recommendation describes a format of metadata based on the Audio Definition Model (ADM) specified in Recommendation ITU-R BS.2076, segmented into a time-series of frames. The XML format is used for the serial presentation of the ADM as is the case with the original ADM. The serial presentation of the ADM is designed for use in linear workflows such as live or real-time production for broadcasting and streaming applications. This Recommendation does not cover the transport method or bit-packing of the metadata, or the format of the audio samples to which the metadata relates.
