ISO/IEC 23001-10:2015 defines a storage format for timed metadata metrics. The timed metadata metrics can be associated with other tracks in the ISO Base Media File Format. Typical timed metadata, quality and power consumption information and their metrics, are defined in the specification for carriage in files based on the ISO Base Media File Format (ISO/IEC 1449612 and ISO/IEC 1544412). The timed metadata can be used for multiple purposes including supporting dynamic adaptive streaming.
